Bitzer to launch new hydrocarbon compressors

GERMANY: Bitzer is to expand its range of compressors with new models for use with hydrocarbon refrigerants.

New versions of its Orbit scroll compressor series, specially designed for R290 (propane), and a redesigned CSHP compact screw compressor for operation with propane R290 and R600a (isobutane) will be featured at this month’s Mostra Convegno Expocomfort show in Milan.

Whether for heat pumps, air conditioning or process and IT cooling, the new ORBIT PRO scroll compressors open a wide range of sustainable applications. BITZER is expanding its ORBIT scroll compressor series with a version specially designed for the future-proof refrigerant R290 (propane). 

With evaporation temperatures between -30°C and 30°C and condensing temperatures between 10°C and 80°C, the new Orbit Pro scroll compressors are suitable for air conditioning, process and IT cooling or reversible heat pumps.

The Orbit Pro series delivers a cooling capacity of between 16kW and 64kW and a heating capacity of between 21kW and 82 kW at standard reference conditions SST +5°C/SDT 50°C/50 Hz. Displacements are between 19.8m3/h and 77.2m3/h at 50Hz.

CSHP screw

The redesigned CSHP compact screw compressor series is said to  feature expanded application limits to meet all requirements of sustainable installations. 

Equipped with an integrated oil separator and built-in suction gas-cooled motor, they are suitable for compact comfort and process cooling as well as heat pump systems. Ex-works, the compressors will come with the SE-i1 protection device, offering comprehensive protection, and simplifying commissioning and servicing. 

For R290, CSHP compressors will be available with a displacement from 197m3/h to 910m3/h at 50Hz with options for mechanical capacity control and VSD operation. For R600a, displacements range from 197m3/h to 1,120m3/h at 50Hz. External frequency inverter operation is also possible.
