Part load efficiency

All of BITZER’s ACP packs can come equipped with a variable frequency drive. A VFD ensures system stability and a more efficient part load performance than other unloading methods. Years of experience has proven that compressors operate at part load (75% or below) for the vast majority of time. A VFD capitalizes on this to increase system efficiency. Furthermore, multiple compressors greatly increases part load efficiency by keeping running compressors closer to full load, where the efficiency is highest.

High efficiency motors

IEC premium efficiency motors
Inverter rated duty with 70Hz option
Standard: IP55
Option: Different voltages on request

Energy efficiency – no suction check valve

BITZER ACP packs utilize internal check valves on the compressors to prevent the rotors from spinning backwards when the compressor is off. This feature is complemented by an oil solenoid/stop valve to ensure that oil does not flow while the compressor is not running. These features eliminate the need for a suction check valve which would create unnecessary pressure drop and decrease or waste system efficiency.
