Browse Refrigeration Compressors
Refrigeration compressors are used in a wide range of cooling systems, from commercial freezers and refrigeration equipment to industrial cooling applications.
At Diamond Compressors, we supply new refrigeration compressors for a variety of system requirements. Our range includes models suitable for low, medium, and high evaporating temperatures, depending on the compressor model and refrigerant used.
Available options include reciprocating, scroll, screw, and rotary designs. Scroll and screw compressors can also offer quieter operation, making them a suitable choice for applications where noise levels need to be kept low.
Our compressors are available throughout the UK and worldwide. UK customers can also benefit from our lift & shift service, helping with the safe handling and movement of equipment.
Whether you are replacing an existing compressor or specifying a new refrigeration system, browse our range below or contact our team for help choosing a suitable model.
About Refrigeration Compressors
A refrigeration compressor is an important part of a cooling system. It draws low-pressure refrigerant vapour from the evaporator, compresses it, and sends it to the condenser at a higher pressure.
This helps the refrigerant release the heat it has absorbed from the cooled space. The refrigerant then moves through the rest of the system before returning to the compressor, allowing the cooling cycle to repeat.
Refrigeration compressors are available in several designs. Each type works differently and is suited to different applications, cooling capacities, and system requirements.
- Reciprocating compressors: Use pistons that move back and forth inside cylinders to compress refrigerant. They are available in a range of sizes and are used in commercial and industrial refrigeration systems. Commercial reciprocating compressors are commonly used where reliable cooling performance is required.
- Screw compressors: Use two rotating screws to continuously compress refrigerant. They are commonly used in larger refrigeration and cooling systems that require continuous operation.
- Scroll compressors: Use two spiral-shaped scrolls to compress refrigerant. They are compact and efficient and can offer quieter operation and a lower noise level.
- Rotary compressors: Use rotating components to compress refrigerant. Rotary compressors are commonly used in smaller refrigeration and air conditioning systems. Rotary vane compressors are one example of this type of compression design.
- Centrifugal compressors: Use high-speed rotating components to increase refrigerant pressure. They are generally used in larger systems where high cooling capacity is required.
Refrigeration compressors can also be supplied in different configurations, including hermetic, semi-hermetic, and open designs.
The right compressor will depend on the requirements of your system, including the required cooling capacity, refrigerant type, evaporating temperature, condensing temperature, power consumption, and available space.
