Why Commercial Chillers Matter for Kenyan Business
Walk into any successful supermarket, restaurant, hotel, brewery, dairy plant or hospital in Kenya. Behind the scenes, you will almost certainly find a commercial chiller quietly doing its job. Furthermore, every fresh meat counter, every cold drinks display, every air-conditioned shopping mall, and every batch of properly fermented beer depends on chiller technology. As a result, commercial chillers are the silent workhorses of Kenya’s modern economy.
However, “commercial chiller” can mean very different things. For instance, it can mean a walk-in chiller room for storing fresh produce. Likewise, it can mean a process water chiller for a brewery or dairy. Moreover, it can mean a large chilled-water air conditioning system serving a 20-floor building. Additionally, it can mean a glycol chiller serving a row of beverage taps in a hotel bar. Therefore, choosing the right chiller for your application is one of the most consequential decisions a Kenyan business can make.
At Spinel Dynamics Group, we have spent over a decade designing, supplying, installing and maintaining commercial chillers in Kenya. Specifically, we have built walk-in chillers for hotels in Diani, glycol chillers for craft breweries in Karen, process chillers for dairy plants in Limuru, and large chilled water plants for commercial towers in Westlands. Therefore, this complete guide brings together everything you need to know before buying, installing or upgrading a commercial chiller in Kenya.
What Is a Commercial Chiller?
A commercial chiller is a refrigeration system. Specifically, it cools either air, water, glycol, or product directly. Moreover, it serves a business, industrial or institutional application — rather than a domestic one. As a category, commercial chillers cover a wide range of equipment. Importantly, this includes walk-in chiller rooms, water chillers, glycol chillers, process chillers and chilled water air conditioning plants.
Generally, the common thread is the temperature range. For most commercial chillers, this sits between 0°C and +12°C. Notably, this is above freezing, which distinguishes chillers from freezers. By contrast, freezers operate at -18°C and below. Furthermore, chillers handle larger capacities than domestic refrigeration. Additionally, they run 24/7 in demanding commercial environments.
Commercial Chillers vs Freezers vs Air Conditioners
These terms get used loosely in the Kenyan market. Therefore, here is how we distinguish them at Spinel Dynamics Group.
Commercial chillers operate above 0°C — typically 0°C to +12°C. Moreover, they handle food, drinks, pharmaceuticals, process fluids or air. Generally, they suit applications where products must stay cold but not frozen.
Freezers and blast freezers operate below 0°C — typically -18°C to -45°C. As a result, they suit frozen storage and rapid freezing applications.
Air conditioners cool air specifically for human comfort. Typically, they target 22–25°C indoor temperature. By contrast, commercial chillers usually cool air to colder setpoints, or cool liquids and products directly.
Where chiller and air conditioner overlap (specifically in large chilled-water HVAC systems), the equipment is sometimes called a “comfort chiller” or “HVAC chiller”. Our team helps clients distinguish requirements clearly from the start.
Types of Commercial Chillers Available in Kenya
Different applications need different chiller types. Therefore, choosing the right type is the foundation of every successful chiller project. Below are the main categories we supply.
1. Walk-In Chiller Rooms (0°C to +8°C)
Walk-in chiller rooms are the most common commercial chillers in Kenya. Essentially, they are insulated rooms built from prefabricated polyurethane (PU) panels. Furthermore, they are fitted with a refrigeration unit and digital temperature controllers. As a result, they store fresh meat, dairy, fruits, vegetables, beverages, flowers and pharmaceuticals.
Typically, walk-in chiller temperatures sit between 0°C and 8°C. Specifically, fresh meat chillers run at 0–4°C. Likewise, dairy chillers run at 2–4°C. Additionally, beverage chillers run at 4–8°C. Moreover, flower cold rooms run at 1–4°C with high humidity.
Sizes range widely. For instance, a small butchery may need only 8–10 m³. By contrast, a hotel may need 40–60 m³. Furthermore, a supermarket distribution centre may need 200+ m³. Either way, we design and build walk-in chillers across Kenya — from neighbourhood butcheries to major export packhouses.
2. Air Conditioning Water Chillers (HVAC Chillers)
Air conditioning water chillers serve very large buildings. Specifically, they produce chilled water at 6–8°C. Then this water is pumped through insulated pipes to Air Handling Units (AHUs) and Fan Coil Units (FCUs) throughout the building. As a result, the building gets centralised, efficient air conditioning.
Generally, HVAC chillers suit projects too large for VRF systems. For example, this includes shopping malls, hospitals, airports, large hotels, factories, high-rise office towers and university campuses. Notably, capacities range from 50 tons (small applications) up to thousands of tons (major commercial buildings).
We design and install HVAC chiller plants for institutional and commercial projects across Kenya. Specifically, we work with Carrier, Trane, York, Daikin Applied, Climaveneta and Mitsubishi chiller technology.
3. Air-Cooled vs Water-Cooled Chillers
HVAC and process chillers come in two main configurations.
Air-cooled chillers reject heat directly to outside air via condenser fans. Notably, they are most common in Kenya. Generally, they suit projects up to about 500 tons. Moreover, they are simpler to install and maintain because no cooling tower is needed. However, they take up more outdoor space and are less efficient than water-cooled equivalents in hot weather.
Water-cooled chillers reject heat to water circulated through a separate cooling tower. As a result, they are more compact and significantly more efficient — particularly in hot, humid coastal environments. However, they require additional equipment (cooling towers, condenser water pumps, water treatment) plus regular cooling tower maintenance. Generally, they suit projects above 200 tons where efficiency justifies the complexity.
For each project, our engineers compare both options. Then we recommend the right choice based on cooling load, climate, water availability, space, and total cost of ownership.
4. Process Water Chillers
Process chillers cool water (not air) for specific industrial processes. For instance, applications include cooling plastic injection moulding machines, hydraulic systems, laser cutters, CNC machines, ultrasonic cleaning baths, dental equipment, MRI scanners, X-ray machines, induction heating systems, and laboratory equipment.
Typically, process chiller temperatures sit between 4°C and 20°C, depending on application. Moreover, capacities range from 1 kW (small lab chillers) up to 1,000+ kW (large industrial processes). Importantly, process chillers often need precise temperature control — sometimes within ±0.5°C.
Notable brands we install include S&A, MTA, Daeil, Trane, Carrier, Tongfei, and several other established process chiller manufacturers.
5. Glycol Chillers
Glycol chillers cool a propylene glycol/water mixture instead of pure water. Specifically, propylene glycol prevents freezing at temperatures below 0°C. As a result, glycol chillers can operate at -10°C or below without ice formation. Moreover, they reach the very low temperatures needed for some demanding applications.
Common applications include the following. Firstly, beer line cooling and bar dispense systems — keeping beer at the perfect serving temperature from cellar to tap. Secondly, craft breweries — controlling fermentation temperature and conditioning beer. Thirdly, dairy processing — chilling milk rapidly after pasteurisation. Fourthly, ice rinks — cooling the ice surface. Finally, food processing — chilling sauces, dough and other products.
We supply glycol chillers from brands including MTA, S&A, Tongfei, and specialist brewery chiller manufacturers. Notably, capacities range from 2 kW (small bar dispense) up to 200+ kW (medium-scale brewery and dairy).
6. Beverage and Beer Chillers
Beer dispense chillers are smaller glycol chillers. Specifically, they sit in hotel bar cellars, restaurant back rooms, or commercial brewery taprooms. Then they cool a glycol loop that runs to multiple beer taps. As a result, beer pours at consistent serving temperature regardless of distance from the keg.
In addition, beverage chillers may include the following equipment. First, cold rooms for storing kegs at the correct serving temperature. Second, draught beer dispense systems with integrated cooling. Third, post-mix carbonator chillers for soft drink dispense.
Typically, we install beer and beverage chillers for hotels, restaurants, sports bars, breweries and event venues across Kenya.
7. Display Chillers and Commercial Refrigeration
Display chillers are customer-facing refrigerated cabinets. Specifically, they display food and beverages attractively. Common types include the following. First, multi-deck open display chillers for supermarkets. Second, glass-door upright chillers for retail and back-of-house. Third, serve-over counters for butcheries and delis. Fourth, patisserie display chillers for cakes and pastries. Fifth, beverage display coolers for soft drinks and bottled drinks.
For full detail on display chillers, see our dedicated guide on display counters and production chillers.
8. Pharmaceutical Chillers
Pharmaceutical chillers maintain a tightly controlled 2°C to 8°C temperature range. Notably, this is the standard storage range for most vaccines, biologics, insulin, blood products, reagents and temperature-sensitive medicines.
Importantly, pharmaceutical chillers must meet WHO and GDP (Good Distribution Practice) compliance. Specifically, this includes continuous temperature monitoring, alarm systems, backup refrigeration, validated mapping studies, and detailed documentation.
We build pharmaceutical chillers in three main configurations. Firstly, walk-in pharma cold rooms for distributors and large hospitals. Secondly, upright pharma fridges for clinics and pharmacies. Finally, portable cold chain units for vaccine transport and remote outreach.
9. Process Refrigeration for Specific Industries
Many Kenyan industries need application-specific chillers. For example, this includes the following:
- Dairy — milk bulk tanks and plate coolers for farm-level milk chilling
- Floriculture — pre-cooling tunnels and flower cold rooms for the cut flower export industry
- Fish processing — slurry ice systems and rapid chillers for fish handling
- Bakeries — water chillers for dough mixing in hot climates
- Wineries — must chillers and fermentation chillers
- Confectionery — chocolate enrobing tunnels and tempering chillers
For each application, we work with specialist process refrigeration manufacturers to deliver fit-for-purpose systems.
10. Mobile and Portable Chillers
Sometimes, fixed chiller installation is impractical. Therefore, we supply and rent portable chiller units for events, temporary cooling needs, emergency backup, and short-term contracts. Generally, capacities range from 5 kW (small spot cooling) up to 200 kW (industrial events).
How Commercial Chillers Work: Inside the Technology
All commercial chillers use the same fundamental refrigeration cycle. However, the implementation varies significantly. Therefore, understanding the basics helps you make better buying decisions.
The Basic Refrigeration Cycle
The cycle has four main stages. Firstly, a compressor pressurises refrigerant gas, raising its temperature. Secondly, the hot gas flows through a condenser where outside air or water carries the heat away. As a result, the refrigerant condenses to a liquid. Thirdly, the liquid passes through an expansion valve, dropping in pressure and becoming very cold. Finally, the cold refrigerant flows through an evaporator where it absorbs heat from the water, air or product being cooled. Then the cycle repeats.
For commercial chillers specifically, the evaporator usually cools water or glycol (rather than air directly). Then this chilled water is pumped to where cooling is needed.
Chiller Components
Every commercial chiller has the following major components.
Compressor — the heart of the chiller. Common types include scroll, screw, reciprocating, and centrifugal. Each type suits different capacity ranges and applications. For example, scroll compressors suit small to medium chillers (up to 100 tons). By contrast, screw compressors suit medium to large chillers (100–500 tons). Furthermore, centrifugal compressors suit very large chillers (500+ tons).
Condenser — air-cooled or water-cooled, as discussed above.
Evaporator — typically a shell-and-tube heat exchanger. Specifically, refrigerant flows through one side, water or glycol through the other.
Expansion device — usually a thermostatic expansion valve (TXV) or electronic expansion valve (EXV).
Controls — modern chillers use sophisticated digital controllers. Specifically, these manage compressor staging, temperature setpoints, alarms, and energy efficiency.
Pumps — chilled water pumps circulate the cooled fluid to the application. Additionally, water-cooled chillers need condenser water pumps for the cooling tower loop.
Cooling tower (water-cooled only) — rejects heat from the condenser water to outside air via evaporation.

Sizing a Commercial Chiller Correctly
Correct sizing is where most failed commercial chiller installations actually fail. Sadly, this happens long before the equipment ever has a chance to break.
Walk-In Chiller Sizing
For walk-in chillers, sizing follows several steps. First, calculate the required internal volume based on stock storage needs plus growth. Second, calculate the heat load — including conduction through walls/ceiling/floor, product cooling load (when fresh stock is added), air infiltration through the door, lights and fans, people working inside, and respiration heat from any fresh produce. Third, select refrigeration capacity to handle the total heat load on the hottest day of the year. Fourth, add a safety margin (typically 15–20%) for peak conditions and future growth.
HVAC Chiller Sizing
For HVAC chillers serving air conditioning systems, sizing requires a full building cooling load analysis. Specifically, this includes the following inputs. Firstly, building envelope (walls, glazing, roof, orientation). Secondly, internal heat gains (people, lights, equipment, computers). Thirdly, fresh air ventilation requirements. Fourthly, climate data for the specific Kenyan location. Finally, operating schedule and diversity factors.
Typically, the result is expressed in tons of refrigeration (TR) or kilowatts (kW). For example, 1 TR = 3.5 kW = 12,000 BTU/hr. Generally, a typical Nairobi office building needs roughly 1 TR per 25–35 m² of conditioned area. However, this varies significantly based on glazing, orientation and internal loads.
Process Chiller Sizing
For process chillers, sizing depends on the specific application. Specifically, you need to know the heat load to be removed, the process supply temperature, the temperature rise allowed, and the cooling fluid flow rate. Generally, the equipment manufacturer can specify the required chiller capacity. Therefore, we work closely with both clients and equipment suppliers to size process chillers correctly.
Glycol Chiller Sizing
For glycol chillers, sizing requires several inputs. Firstly, the application temperature (e.g., -5°C for beer lines, -10°C for ice rinks). Secondly, the heat load at that temperature. Thirdly, the glycol concentration needed (typically 30–40% propylene glycol). Finally, the system pressure drops and pump head requirements. Importantly, glycol concentration affects both freeze protection AND heat transfer efficiency. As a result, getting this balance right matters.

Industries Using Commercial Chillers in Kenya
Commercial chillers serve almost every sector of Kenya’s modern economy. Below are the main industries where we deliver chiller projects.
Hospitality and Food Service
Hotels, restaurants, cafés and catering operations all depend on commercial chillers. Specifically, walk-in chillers store fresh meat, dairy, fruits, vegetables and beverages. Additionally, larger hotels use chilled water HVAC for guest comfort. Furthermore, hotel bars use glycol chillers for beer dispense systems.
Retail and Supermarkets
Supermarkets and large retail operations use multiple chiller types. For instance, walk-in chillers store bulk fresh stock. Additionally, multi-deck display chillers present products to customers. Moreover, large supermarket chains use centralised pack refrigeration with remote chillers. Generally, we serve Naivas, Carrefour, Quickmart, Chandarana and many independent operators.
Healthcare and Pharmaceuticals
Hospitals, clinics, pharma distributors and laboratories need precise temperature control. Specifically, pharmaceutical chillers store vaccines, biologics, blood and reagents. Additionally, hospital HVAC chillers serve patient wards, theatres and laboratories. Moreover, mortuaries use chillers for body storage. Importantly, all these applications need backup power and continuous monitoring.
Floriculture and Horticulture
Kenya’s cut flower export industry — the second-largest in the world — depends entirely on cold chain. Specifically, flower cold rooms cool roses, carnations, lilies and other flowers to 1–4°C within hours of harvest. Additionally, pre-cooling tunnels rapidly cool flowers before bulk storage. Moreover, vegetable exporters use chillers for produce destined for European supermarkets. Our team has built chillers for major flower farms in Naivasha, Limuru, Thika, Nakuru and Mt Kenya region.
Dairy and Agro-Processing
Dairy processors use chillers extensively. Specifically, applications include rapid milk chilling after pasteurisation (plate coolers), bulk milk storage chillers, yoghurt fermentation chillers, and finished product cold storage. Additionally, we serve fruit juice producers, food processors, and beverage bottlers across Kenya.
Fish and Seafood
Fish processors at the coast and at Lake Victoria use chillers for handling fresh fish, slurry ice production, and chilled stock storage before processing. Furthermore, exporters use specialised chiller installations for export-grade processing.
Brewing and Beverage Production
Craft breweries are growing fast in Kenya. Specifically, they need glycol chillers for fermentation control, conditioning, and dispense. Additionally, traditional brewers and beverage producers use process chillers for bottling lines, carbonation, and beverage cooling.
Commercial Real Estate and Office Buildings
Multi-floor office buildings in Westlands, Upper Hill, Kilimani and other Nairobi business districts use chilled water HVAC systems for centralised air conditioning. Similarly, retail malls, mixed-use developments and hotel towers rely on chilled water plants.
Manufacturing and Industry
Manufacturing operations use process chillers for many applications. For example, plastic injection moulding, hydraulic systems, laser cutters, induction heaters, and CNC machines all need precise temperature control. Therefore, we serve manufacturers across the industrial belt — Mombasa Road, Athi River, Thika, and other industrial zones.
Education and Institutions
Universities, colleges, schools and government institutions use chillers for HVAC, laboratory equipment, kitchen storage, and various specialised applications.
Data Centres and Critical IT
Server rooms and data centres need precise cooling 24/7. Specifically, we supply and install precision cooling chillers, CRAC (Computer Room Air Conditioning) units, and chilled water systems for critical IT infrastructure.
Refrigerant and Environmental Compliance
Kenya has ratified the Kigali Amendment to the Montreal Protocol. As a result, the country has committed to phase down high-GWP hydrofluorocarbon (HFC) refrigerants. Progressively, NEMA (the National Environment Management Authority) is enforcing this.
For commercial chillers, common refrigerants include the following.
R134a — still widely used in chillers; medium GWP; supply remains stable.
R410A — common in package HVAC and smaller chillers; being phased down.
R32 — lower-GWP alternative for smaller commercial chillers; increasingly common.
R1234ze and R513A — modern low-GWP HFO blends used in new HVAC chiller designs.
R744 (CO₂) — natural, very low GWP refrigerant; used in modern transcritical systems for some commercial chiller applications.
R290 (Propane) — natural, very low GWP; used in some smaller chiller applications with charge limit considerations.
R717 (Ammonia) — natural refrigerant common in large industrial chillers where safety distances allow.
For new commercial chiller projects, we recommend specifying future-proof, low-GWP refrigerants. Additionally, our refrigeration technicians are certified for proper refrigerant handling. Importantly, we never vent refrigerant to atmosphere. Furthermore, we help clients plan transitions away from older refrigerants like R22 and R404A.
The Installation Process: How We Deliver Your Project
Our commercial chiller installation process follows a proven four-step approach. Notably, it has been refined over a decade of Kenyan projects.
Step 1: Free Site Survey and Consultation
A qualified refrigeration engineer visits your site at no cost. Specifically, we measure available space, assess electrical capacity, evaluate the location for outdoor equipment, identify cooling water sources (for water-cooled chillers), check structural loads, and discuss your cooling requirements. Furthermore, we discuss your operating schedule, peak loads, and future expansion plans.
Step 2: Engineering Design and Quotation
Back at our office, we produce a complete engineering design package. Specifically, this includes load calculations, chiller selection with detailed specifications, schematic drawings, electrical load schedules, refrigerant choice, controls specification, and a transparent itemised quotation. Additionally, we propose options at different brand and efficiency tiers so you can make an informed choice.
Step 3: Manufacturing and Installation
Once approved, we order the chiller and ancillary equipment from our partner brands. On site, our installation team prepares the foundation or mounting platform, positions the chiller, runs chilled water piping with proper insulation, installs the cooling tower (water-cooled systems), completes electrical wiring with appropriate protection, installs controls and sensors, and connects to the building’s distribution system. For chilled water HVAC systems, we additionally install pumps, AHUs/FCUs, and ductwork where applicable.
Step 4: Commissioning, Testing and Handover
Before handover, we conduct comprehensive commissioning. First, we pressure-test refrigerant and water circuits. Then we flush the chilled water system to remove construction debris. Next, we charge the refrigerant to specification. Afterwards, we run the chiller through staged startup, verifying every safety device. Subsequently, we balance flows, verify temperature stability, test all alarms, and document baseline performance data. Finally, we train your operators on running, alarm response, basic troubleshooting and emergency procedures. As part of handover, you receive operation manuals, drawings, charge records, and our 24/7 emergency support contact.
Maintenance: Protecting Your Chiller Investment
A commercial chiller is a major capital investment. Specifically, prices range from KSh 450,000 for a small walk-in to KSh 200 million+ for a major chilled water plant. Therefore, proper maintenance is what separates 15+ years of reliable service from premature failure.
Daily Operator Tasks
Several checks should happen every day. First, check displayed temperature against setpoint. Next, note any alarms. Then listen for unusual compressor or fan noise. Furthermore, check chilled water flow indicators. Additionally, verify cooling tower water level (water-cooled systems). Finally, log running parameters.
Weekly Tasks
Each week, several inspections matter. Specifically, check refrigerant sight glass for bubbles or moisture. Additionally, inspect strainers and filters. Moreover, check water treatment chemical levels (water-cooled systems). Finally, log temperatures, pressures and alarm data.
Monthly Professional Service
Once a month, several tasks are essential. First, clean condenser coils on air-cooled chillers (the single most important maintenance task). Next, inspect cooling tower fill and basin (water-cooled). Then test high-temperature and safety alarms. Additionally, verify controller setpoints. Furthermore, inspect electrical connections. Finally, take water samples for testing (water-cooled systems).
Quarterly Professional Service
Every three months, we recommend a full professional service. Specifically, this covers complete electrical safety inspection, refrigerant pressure and superheat measurement, compressor performance check, fan motor inspection and lubrication, evaporator and condenser cleaning, water treatment service (water-cooled), pump inspection, and a detailed service report.
Annual Major Service
Once a year, we recommend a deep service. Specifically, this includes compressor oil sample analysis, refrigerant leak detection using electronic detector, full controller and alarm system test, pressure relief valve inspection, cooling tower full clean and disinfection (Legionella prevention), and detailed performance benchmark.
Emergency Response
When a commercial chiller fails, the consequences scale fast. For example, a hotel chiller failure on a hot afternoon affects every guest. Likewise, a process chiller failure can halt a production line at KSh 100,000+ per hour. Therefore, our 24/7 emergency line ensures rapid response across Nairobi and same-day response across major Kenyan towns.
Maintenance Contracts
For commercial clients, we offer monthly, quarterly and annual maintenance contracts. Specifically, these cover scheduled servicing, priority emergency response, discounted spare parts, free remote troubleshooting, and predictable annual cost. Notably, a chiller maintenance contract is the highest-ROI investment most operators can make. Indeed, a single avoided breakdown often pays for several years of contract fees. Currently, we deliver contract servicing across Nairobi, Mombasa, Kisumu, Nakuru, Eldoret, Naivasha, Thika, Kilifi, Malindi and Diani.
Common Commercial Chiller Problems and Solutions
After more than a decade working on chillers across Kenya, here are the problems we see most often. Additionally, here is how we resolve them.
Chiller Not Achieving Setpoint Temperature
Several causes are possible. Most commonly, refrigerant undercharge from a slow leak is the culprit. Next most common is a dirty condenser coil or cooling tower. Beyond that, fouled evaporator tubes can be at fault. Sometimes, compressor performance has degraded. Additionally, controller misconfiguration may be responsible. Furthermore, overloaded conditions (more cooling demand than the chiller can handle) can be the issue. Either way, diagnosis requires systematic measurement of pressures, temperatures and flow rates.
Compressor Short-Cycling
Several causes contribute to short-cycling. Specifically, these include refrigerant undercharge, faulty pressure switches, controller misconfiguration, undersized buffer tank (for HVAC chillers), or sudden load changes. Importantly, short-cycling drastically reduces compressor life. Therefore, it must be resolved urgently.
High Operating Pressures
Causes include dirty condenser coils, cooling tower fouling or low water flow, non-condensable gases in the refrigerant circuit, overcharged refrigerant, or excessive cooling load. Generally, all of these are diagnosed and resolved by systematic service.
Low Operating Pressures
Causes include refrigerant leakage and undercharge, blocked filters or driers, faulty expansion valve, low evaporator water flow, or excessive evaporator fouling. As a result, capacity drops dramatically. Therefore, prompt diagnosis and repair matters.
Water Leaks
Sources include cooling tower piping, chilled water piping, valve seals, pump seals, or condenser tube failures. Importantly, undetected water leaks can damage chiller foundations, electrical equipment and nearby property. Therefore, we install leak detection and prompt repair protocols.
Excessive Electricity Consumption
This is often the most expensive but least visible problem. Specifically, causes include dirty condenser surfaces, refrigerant undercharge, cooling tower fouling, compressor wear, controller misconfiguration, oversized chiller short-cycling, or pump issues. Generally, an energy audit identifies the issues and a proper service recovers 20–40% of lost efficiency. Importantly, the payback is often less than 12 months.
Cooling Tower Issues (Water-Cooled Chillers)
Common cooling tower problems include scaling and fouling, biological growth (including Legionella risk), drift and water loss, fan motor failure, and water treatment chemistry imbalances. As a result, regular cooling tower maintenance is critical for both efficiency and health safety.
Sudden Total Failure
Causes range from electrical issues (tripped breaker, blown contactor, failed motor) to mechanical failure (compressor seizure, pump failure) to controls failure. Either way, our emergency team gets you running again — often within hours.

Frequently Asked Questions (FAQ)
How much does a commercial chiller cost in Kenya?
Commercial chiller prices vary widely. Generally, they range from around KSh 280,000 for a small beer dispense glycol chiller to KSh 200 million+ for a major chilled water HVAC plant. Typically, a small walk-in chiller (10 m³) costs KSh 450,000–800,000. Similarly, a medium walk-in chiller (25 m³) costs KSh 800,000–1.4 million. Meanwhile, a 100 TR air-cooled HVAC chiller costs KSh 8.5–16 million. Importantly, the right price depends entirely on application, capacity and brand.
What is the difference between a chiller and a freezer?
A chiller operates above 0°C — typically 0°C to +12°C. Specifically, it keeps products cold but not frozen. By contrast, a freezer operates below 0°C — typically -18°C to -45°C. As a result, it freezes products. Notably, most commercial operations need both: chillers for fresh products and freezers for frozen inventory.
What is the difference between an air-cooled and water-cooled chiller?
An air-cooled chiller rejects heat to outside air via condenser fans. As a result, it is simpler to install and maintain. Moreover, no cooling tower is needed. However, it takes more outdoor space and is less efficient in hot weather. By contrast, a water-cooled chiller rejects heat to water circulated through a separate cooling tower. Consequently, it is more compact and significantly more efficient. However, it requires additional equipment and regular maintenance. Generally, air-cooled suits projects up to 500 tons, while water-cooled becomes preferable above this.
How long does it take to install a commercial chiller?
Installation time varies by project size. Typically, a small walk-in chiller takes 1 to 2 weeks. Meanwhile, a medium walk-in chiller takes 2 to 4 weeks. Furthermore, a small HVAC chiller plant takes 4 to 8 weeks. By contrast, a major commercial HVAC chiller project with full building distribution can take 3 to 9 months depending on equipment lead times and building works.
Do you supply commercial chillers outside Nairobi?
Yes, we serve all of Kenya. Specifically, we design, supply, install and maintain commercial chillers across Mombasa, Kisumu, Nakuru, Eldoret, Naivasha, Kilifi, Malindi, Diani, Thika, Machakos, Athi River, Nyeri, Meru, Nanyuki, Kakamega, and Kisii. Additionally, we serve parts of the wider East African region including Uganda, Tanzania and Rwanda.
Can you repair commercial chillers installed by other contractors?
Yes, absolutely. Specifically, we service and repair commercial chillers regardless of original supplier. For example, this includes Carrier, Trane, York, Daikin Applied, Climaveneta, Mitsubishi, Bock, Bitzer or any other manufacturer. Additionally, we can retrofit, upgrade or expand existing installations as your business grows.
What refrigerants do you use in commercial chillers?
We design new commercial chillers with future-proof, low-GWP refrigerants where possible. Specifically, common choices include R134a, R32, R1234ze, R513A, R744 (CO₂), R290 (propane), and R717 (ammonia, for large industrial applications). Additionally, for existing systems we support R410A and R404A maintenance. Moreover, we help clients plan phased transitions away from older refrigerants.
Do you offer chiller maintenance contracts?
Yes, several options are available. Specifically, we offer monthly, quarterly and annual maintenance contracts. Each option covers scheduled servicing, priority emergency response, discounted spare parts, remote troubleshooting and predictable annual cost. Importantly, chiller maintenance contracts are typically one of the highest-ROI investments commercial operators can make.
What backup systems do you recommend for critical chillers?
For mission-critical applications, several backups are wise. Specifically, this applies to pharmaceutical chillers, data centre cooling, hospital HVAC, and large food storage. Generally, we recommend automatic generator transfer switching, redundant chillers (N+1 configuration so one chiller can fail without losing capacity), continuous remote temperature monitoring with SMS and email alerts, UPS protection for controls, and detailed emergency response procedures with stocked critical spares.
Can you design and build complete chilled water HVAC plants?
Yes, this is one of our specialist areas. Specifically, we design and install complete chilled water HVAC systems including chillers, cooling towers (water-cooled), pumps, primary and secondary loops, AHUs, FCUs, ductwork, controls, and Building Management System (BMS) integration. Additionally, we work alongside MEP consultants and main contractors on large commercial projects.
Do you supply spare parts for commercial chillers?
Yes, we maintain working stock of common spares. Specifically, this includes controllers, pressure switches, capacitors, contactors, sensors, expansion valves, sight glasses and drier cores. Additionally, we have direct supply relationships with major manufacturers for compressors and other major components.
Can I see references and past projects?
