Heat Recovery Systems

Our heat recovery system exploits the otherwise wasted heat generated by a refrigeration unit’s compressor to heat water within the heat recovery vessel.

The water will typically reach 55ºC to 65ºC with the heat provided by the refrigerant gas and can be further boosted by the electric element inside the heat recovery device.

The hot water produced by the heat recovery unit can be used for cleaning milk vats and milking equipment or to supply pre-heated water to existing hot water services already cleaning this equipment

Operation Principle

The heat recovery tank is connected to the refrigeration system between the compressor and the condenser. The (hot) discharge refrigerant gas passes through the heat recovery tank jacket which heats the water inside the tank. The refrigerant gas coming out of the tank is cooler due to the heat exchanged with the water inside prior to entering the condenser. This has a positive effect on the condensers’ performance and on the efficiency of the whole refrigeration system.
