    The CRII System

    Capacity control is often required to match the output of a refrigeration, air-conditioning or heat pump system to the actual requirement. It prevents high switching frequency of the compressor and, thus, ensures more efficient operation of the system.

    The CRII system is designed for the special requirements of intelligent system controls.

    This enables higher cycling frequency of capacity control.

    As a standard feature BITZER utilises a proprietary controller to operate and control the functionality of the BITZER CRII capacity control system.

    The controller will start/stop, load/unload the compressor based upon the suction pressure set point.

    The capacity steps can be activated /deactivated rapidly (5 s).
