With the use of carbon dioxide as a natural refrigerant becoming increasingly popular, BITZER recently announced the launching of an enhanced range of CO2 OCTAGON compressors for air-conditioning, medium and low temperature refrigeration applications. According to the company’s press release, customers can now benefit both from a large, technologically sophisticated range of BITZER CO2 compressors and a guarantee of intensive and professional technical support.

BITZER’s proven OCTAGON compressors are optimised for use with CO2 and have short-stroke technology, a smooth-running drive gear and multi-valve technology, being suited for operation with frequency inverters and for parallel switching. In addition, the optimised centrifugal lubrication system reduces the oil carry over to a minimum even with high fluctuations in pressure and speed regulated operation.

For sub-critical CO2 applications, there are now 17 models of the OCTAGON CO2 series, with cooling capacity ranging from 4.4. to 80 kW in low-temperature operation at 50 hertz.
