Air-cooling unit
Compressor-condenser units (CCUs)
A compressor-condenser unit is an outdoor unit that compresses refrigerant, releases heat into the atmosphere, and supplies cold liquid refrigerant to the evaporator in an air handling unit. This allows the ventilation system to cool large volumes of supply air and maintain a comfortable indoor temperature.
What is a compressor-condenser unit?
A compressor-condenser unit is an outdoor unit responsible for producing cooling in ventilation and air conditioning systems. Put simply, it is the “engine” of a refrigerant-based cooling system. The CCU compresses the refrigerant, releases its heat into the atmosphere, and sends the cold liquid refrigerant on to the refrigerant evaporator installed in the air handling unit. This is how the air supplied to the room is cooled.
Design and operating principle
How a compressor-condenser unit is built
The main components of a CCU are the compressor, condenser, fans, relays and controls, along with a protective enclosure. The compressor compresses gaseous refrigerant, significantly raising its temperature. The hot refrigerant flows into the condenser, while the fans draw outdoor air through it. Heat is released into the atmosphere, the refrigerant cools and becomes a liquid, then flows to the indoor unit. The cycle then repeats.
Where CCUs are used
Compressor-condenser units are widely used in central ventilation and air conditioning systems where large volumes of supply air need to be cooled.
- 01Supply and exhaust air handling unitsThe CCU works with a refrigerant cooler in a supply ventilation system.
- 02Office buildingsCentral air conditioning systems for offices and business centers.
- 03Shopping centers and hypermarketsCooling supply air in high-traffic spaces.
- 04Industrial premisesMaintaining temperature conditions in workshops and production facilities.
- 05Data centers and server roomsRemoving heat and cooling air in spaces with high heat loads.
- 06Restaurants, hotels and public buildingsA comfortable indoor climate in areas with large numbers of visitors.

How a CCU works
A compressor-condenser unit operates on a closed refrigeration cycle that continuously cools the supply air.
- 01Compression
The compressor compresses gaseous refrigerant, increasing its pressure and temperature.
- 02Heat rejection
Hot refrigerant flows through the condenser, where fans draw outdoor air through it and carry away the heat.
- 03Condensation
The refrigerant cools, becomes a liquid and flows to the evaporator.
- 04Supply air cooling
The evaporator in the air handling unit draws heat from the refrigerant and cools the supplied air.
- 05Cycle repeats
The refrigerant returns to the compressor and the cycle starts again.

Buy a compressor-condenser unit in Almaty, Astana and other cities in Kazakhstan
An outdoor compressor-condenser unit can be used as part of an air handling unit, a central or ducted air conditioner, or an industrial air conditioning system. Klimatrade specialists select compressor-condenser units to match project requirements, including the required cooling capacity, evaporator type, temperature range, pipe run length, installation conditions and control requirements. We can recommend a CCU for an air handling unit, a CCU for ventilation, a CCU for a central air conditioner or a CCU for a ducted air conditioner. If you need a compressor-condenser unit for air cooling, submit a request—we will calculate the required CCU capacity, recommend the optimal configuration and prepare a commercial proposal. Depending on the application, you can choose a standard compressor-condenser unit or one with an inverter compressor for more precise capacity control. A custom calculation is required to buy a compressor-condenser unit or find out the price of a CCU. The cost depends on the capacity, compressor type, refrigerant, controls, operating mode and operating conditions. We supply compressor-condenser units for commercial and industrial facilities. Compressor-condenser units are available in Kazakhstan, including in Almaty and Astana. Submit a request—Klimatrade specialists will help you select a CCU for industrial air conditioning systems and prepare a solution for your facility.
Frequently asked questions about compressor-condenser units
What is a compressor-condenser unit (CCU)?
It is an outdoor unit that produces cooling for the refrigerant evaporator in a supply ventilation system. It compresses the refrigerant, releases heat into the atmosphere and supplies cooled refrigerant to the indoor circuit.
Where are CCUs used in ventilation systems?
They are used in supply and exhaust air handling units with refrigerant cooling, as well as in central air conditioning systems in office, retail, industrial and public buildings.
How do you select a CCU for ventilation?
Selection takes into account airflow rate, the required cooling temperature, refrigerant cooler capacity, the local climate and air handling unit specifications.
How are CCUs maintained?
Maintenance includes regular condenser cleaning, refrigerant level checks, and diagnostics of the compressor, fans and controls.
Do CCUs have automatic controls?
Yes. Modern CCUs are equipped with controls that coordinate operation with the ventilation unit and maintain the set parameters.
