Description
The compact screw compressors of the CSH2T95 version are designed for high-temperature heat pumps using R1233zd(E) and R245fa refrigerants. These models enable fluid outlet temperatures of up to 120 °C and are developed for process heating systems such as pressurised water heating or low-pressure steam generation. The CSH2T series differs by adapting all essential components to the elevated temperature level. The compressors are only available in combination with VARIPACK frequency converters for speed control. An advanced compressor protection device (SE-i1) monitors and records operating parameters such as pressures and temperatures in real time.
CSH2T95 compressors are only available to OEM system manufacturers with experience in building high-temperature heat pumps.
