Dorin H Series H 4000 CS Semi-Hermetic Compressor

For low-temperature refrigeration systems and industrial cold storage applications, the Dorin H Series H 4000 CS Semi-Hermetic Compressor offers high cooling capacity with its 138.37 m³/h displacement and robust cast iron body. Thanks to its compatibility with R404A and R507 refrigerants, it provides stable performance at low evaporating temperatures down to -45 °C.

High Efficiency for Low-Temperature Applications

The H 4000 CS model is designed for demanding operating conditions such as freezer cold storage rooms, blast freezing units and industrial refrigeration facilities. Its semi-hermetic design offers ease of maintenance and service, while the finned cylinder body efficiently dissipates heat, ensuring long-lasting and quiet operation. The multi-head cylinder arrangement and strong connection flanges, also visible in the image, suit heavy-duty refrigeration systems.
