With the use of carbon dioxide as a natural refrigerant becoming increasingly popular, BITZER now offers an enhanced range of CO₂ Octagon® compressors for air-conditioning, medium and low temperature refrigeration applications.  

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. With these features, they are ideally suited for operation with frequency inverters and for parallel switching. BITZER’s sophisticated oil management is also particularly beneficial for CO₂ applications, the optimised centrifugal lubrication system reduces the oil carry over to a minimum even with high fluctuations in pressure and speed regulated operation.
