BITZER offers kits for tandem and trio units for parallel operations. They consist of two or three compressors connected in parallel and provide significant benefits over individual compressors with the same output. The compound compressor units are distinguished by innovative technical properties and excellent energy efficiency under the seasonal load conditions tolerated by air conditioning systems and heat pumps. The compressors were optimised in terms of low noise levels, highly smooth running and reliability.

  • Efficient capacity control with high ESEER and IPLV thanks to alternating operation between compressors.
  • Proven oil and gas equalisation.
  • Low vibration level thanks to direct installation on fixed rails (no spacer washers required).
  • BITZER Advanced Header Technology (BAHT) piping kit allows many combinations with common piping
  • The ORBIT with VSD capability provides smooth and efficient operation in a wide speed range.
  • The quick response of the ORBIT with VSD allows accurate temperature control.
