Semi Hermetic Recip Compressure
Based on one technical concept, our semi-hermetic reciprocating compressors cover the entire spectrum of applications of conventional, chlorine-free HFC as well as natural refrigerants. They distinguish themselves by a robust valve plate design, a high quality and wear resistant drive gear, are easy-to-service and offer good speed control at minimum energy requirements as well as extremely smooth running. In addition, they incorporate an efficient, suction gas cooled integrated motor. The OCTAGON series of compressors additionally excels by extremely compact dimensions and even further increased smooth running. As of type 4J-13.2 our proven internal oil return system is used.
The semi-hermetic reciprocating compressor models Varicool, Booster and CIC are available for the low temperature range with refrigerant R22. The nominal motor power lies between 0.37 kW and 74 kW.
We have developed these extremely economical reciprocating compressors which compress the refrigerant in two stages, specifically for the extreme low temperature range. By subcooling the liquid the cooling capacity can be increased considerably – at the same time providing significantly increased efficiency of the system.
