ECOLINE TANDEM

Etalase : BITZER RECIPROCATING COMPRESSORS SEMI HERMETIC

Tandem compressors are the simplest way of connecting two compressors in parallel. Turning on and shutting off one compressor allows for a particularly effective graduation of output. The 4- and 6-cylinder models can also be equipped with capacity control systems (cylinder cutoff), allowing them to run with up to four or six levels of output. Particularly for applications with high load fluctuations, this allows for cost-effective and energy-efficient operation under full- and part-load with all conventional refrigerants.


Technical Features

New valve plate design

  • New geometric concept for pressure valves – for low rear expansion.
  • High cooling capacity with minimal energy requirements.
  • The ECOLINE cylinder head system: Flexible operation in tandem.

Motor

  • Efficient under full- and part-load thanks to its broadband characteristics.
  • The universal refrigeration compressor: Motor version 2 for medium and low temperature applications.
  • Motor versions 1 and 3 for special applications.

Capacity control

  • The CRII system – intermittent blocked suction For example, 4-cylinder compressor with CRII on both heads: Range of control from 100% to ~10%

Backward compatible

  • Outer contour as standard: Every ECOLINE is backward compatible.

Drive gear

  • New piston and connecting rod design
