BITZER 2nd generation 2-stage R22

Bitzer Semi hermetic 2-stage S6H-20.2Y

Semi hermetic 2-stage R22 - S6H-20.2Y

BITZER is raising the bar in terms of technology and capacity for expanded low temperature applications with the 2nd generation of 2-stage compressors. This series is the result of extensive research on the basis of years of experience in the construction of highly efficient and solid reciprocating compressors. The gas flow control and working valves are specially adapted for low temperature applications.
