What are condensing units?
Condensing units are temperature control machines that regulates heat by compressing a refrigerant gas, pumping it through an expansion of condenser coils. The air around these coils cool, dehumidify or reheat a space.
A standard condensing unit has three main pieces:
- The condenser.
- The compressor coil.
- A fan
The compressor pumps the refrigerant gas through the system. The compressor coils provide sufficient surface area for the hot refrigerant to pass through. The fan blows the heat from the coils. The refrigerant then condenses and flows back to the building cooling the inside air.

These some of the major players in the condensing unit market. These companies have adopted product launches, investments, acquisitions, agreements, contracts, partnerships, and expansions as growth strategies to enhance their position in the condensing unit market.
Types of Condensing Units
1. Air-cooled condensers
Air-cooled condensers are used to cool the heat of the refrigerant and condense it from a gaseous state to a liquid refrigerant. Typically, this type of condenser uses fin coils, which are usually made of copper tubes and fins, increasing the surface area and allowing heat to be removed from the refrigerant in the condenser.
2. Water-cooled condensers
Water cooled condensers use water as the medium to cool the refrigerant from the gaseous state and condense it into a liquid refrigerant, making the water warmer.
3. Evaporative condenser
Evaporative condensers use both water and air to transfer the heat from the gaseous refrigerant into the condensate. The principle of the evaporative condenser is to combine a water-cooled condenser and a cooling tower into one.
Applications.
There are different models of condensing units specified for the level of evaporation temperatures (high, medium, or low). The application
can be small or large scale with the most common application being
- Hospitals.
- Hotels and restaurants.
- Cold rooms.
- Banks.
- Manufacturing plants
Where to install condensing units.
The condensing unit is located outside the space needing air conditioning. The building external ventilation helps in cooling down the refrigerant gas passing through the compressor and the compressor coil.
Before and when installing condensing units, the engineers at The Cold Room Kenya will visit ensure that the following precautions are in order to:
- The installation location must be well in terms o ventilation. This allows fresh air to flow to the condenser. In an enclosed area, the condensing unit must receive fresh air through the condenser inlet and have an unimpeded hot air outlet.
- Places with strong air currents, direct sunlight, rain, and dust are avoided since they can influence the functionality of the condensing unit.
- The condensing unit and the evaporator are not far away to ensure that no pressure is lost in the tubing thus avoiding accumulation and retention of oil that could damage the compressor.
Conclusion
The condensing units at The Cold Room Kenya are high cooling performance and efficiency, fast and simple selection and installation, therefore, reducing maintenance time, versatile application of temperature application, and they meet all regional and national regulations on energy.
Our units are built for energy efficiency, durability, and optimal performance, ensuring reliable temperature control in commercial and industrial environments in Kenya and East Africa.
The Cold Room Kenya can design and manufacture to customer requirements such as Space constraint provisions for on-site installation and maintenance: we can design the products into smaller sizes. Performance and capacity terms: We use calculation programs to obtain accurate data sheets. Design speed terms: an engineer is available for immediate consultation to produce a design
In terms of use and maintenance: if The Cold Room Kenya designs a 4-circuit heat exchanger, the cover switches to 2 circuits per side for easy on-site maintenance and piping. From the above information we are therefore confident in our service and production. All-round customer satisfaction
