Refrigeration compressor specialist, Bitzer, showcased an extensive range of products at the AHR Expo trade fair in Chicago including its Advanced Header Technology.
The technology means it is now possible to operate different scroll compressors in parallel – without using any active oil management.
This enables Bitzer to offer up to 20 different combinations, with different performance, using Orbit scroll compressors.
For example, users can combine Orbit 6 and 8 compressors in a single system. Also on show was Bitzer's semi-hermetic CO2 reciprocating compressor from the Octagon series for sub-critical and trans-critical cycle applications.
The delivery volumes of the sub-critical cycle Octagon series is between 1.33 m3/h and 46.9 m3/h, and for the trans-critical cycle series, it is between 3.3 m3/h and 37.9 m3/h.
Bitzer has more than 15 years of experience in the manufacture of CO2 compressors.
