Open

Open drive reciprocating compressors are available in two model series: for (H)CFC/HFC refrigerants and ammonia. Due to the open drive design, 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.

Open 2-stage

The open drive, 2-stage reciprocating compressors are optimised for the low temperature refrigeration range. With the optional liquid subcooler, they significantly increase the cooling capacity and efficiency of the entire system. Standard motors can be attached to the compressor via coupling housing or belt drive.
