Semi-hermetic 2-stage

Semi-hermetic 2-stage reciprocating compressors, which compress the refrigerant in two stages, are optimized for the low-temperature refrigeration range. Liquid subcooling significantly increases the cooling capacity and efficiency of the entire system.

Semi-hermetic frequency-controlled

With the built-in preprogrammed frequency inverter of the VARISPEED series, the speed can be infinitely adjusted, which increases efficiency and lowers energy costs. The built-in suction gas cooling of the frequency inverter increases operating reliability and reduces maintenance to visual inspections only.

Open

Open-drive reciprocating compressors are available in two model series: for (H)CFC/HFC refrigerants and for ammonia. Due to the open-drive construction, standard motors can be attached to the compressor via coupling housing or belt drive. Reliability and easy maintenance have made them popular options for years.
