Controls

Protection

Liebert iCOM Controls enhance unit protection with automated routines such as fast restart and freeze protection.

Faster Restart

Recovery times from loss of power or transfer to generator power are reduced. Faster restart decreases temperature rise during these events.

Refrigerant Protection

High Pressure Trip

Shutdown

Shutdown

Freeze Cut Out

Self-healing routines prevent DX refrigerant freeze. As refrigerant pressure approaches thresholds, the controls lower fan speed and compressor capacity so cooling is not disabled due to a low-pressure cut out. At the other end of the spectrum, the controls adjust the compressor down and raise fan speed so cooling is not disabled due to a high pressure condition.
