SEMI-HERMETIC
Universal and environmentally friendly: ECOLINE reciprocating compressors offer high cooling capacity with minimal energy requirements and are optimised for HFC, HFO and low-GWP refrigerants. The optional VARISTEP mechanical capacity control offers high part-load efficiency in medium and low temperature application.

SEMI-HERMETIC FREQUENCY-CONTROLLED
VARIPACK frequency inverters are specially developed for operation with BITZER compressors. Energy can be saved by flexibly adapting a system’s cooling demand and optimally coordinating compressor and frequency inverter. The frequency inverter speaks the language of cooling.


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.
