Compressor control

When the existing control unit of a compressor fails, it can easily be replaced with ours. But even when a compressor is purchased brand new our unit offers a number of major advantages compared to the majority of standard controllers:


Automatic control

The unit can regulate based on the suction pressure or an external sensor on for example a liquid temperature. The compressor can start and stop fully automatated. It can also be switched on and off by connecting a external component via a digital input. The capacity is automatically regulated according to the load on the compressor. The motor flow, suction pressure and discharge pressure can be set as limitation.

Two or more control setpoints are available for flexiblility in the installation. Switching between these setpoints is possible via a digital input. To protect the motor, various timers are included in the control as for example a minimum off time of the motor.

Manual control

In manual operation, the compressors are started and stopped by operating the start and stop button on the screen. This also applies when adjusting the capacity.

Built-in security measures

A number of safety checks have been applied to protect the compressor against technical faults:

All of these safety checks operate in both automatic and manual modes and provide an immediate alarm upon detection of a potential problem.
Possibilities of a ‘variable volume ratio’ control and optional a frequency controller are also included in the control unit.
