Bitzer Reciprocating Compressors
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 with innovative motor technology
The ECOLINE+ series is a further-developed version of the proven reciprocating compressors. By using the refrigerant CO2, innovative line-start permanent-magnet motors and optional intelligent electronics, the series achieves the highest energy efficiency values possible.
Semi-hermetic 2-stage
The 2-stage reciprocating compressors are designed for an extensive application range and boast an optimised drive gear and efficient motor. The highly reliable semi-hermetic series is designed to be robust and suitable for a variety of refrigerants.
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.
Semi-hermetic with liquid receiver
Compact unit comprising efficient ECOLINE compressor and liquid receiver. The components are well coordinated and universal. These units can be used with low-GWP refrigerants, thus making them future-proof.

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.
