Gellert Refrigeration Control

Eliminate Overuse & Compressor Failure

Alternate between multiple compressors, allowing you to sidestep the risk of any “one compressor” getting overworked.

Enjoy the comfort of redundancy. While running multiple compressors, if a single compressor fails, the other will continue working so you don’t have a complete shut-down.

Alternate Condenser fans  increasing the life span of all motors.

Control Functions for Energy Savings

Condenser fans can be controlled from a fixed discharge setting, or a floating pressure – based on outside temperature. Condenser fans can be driven off VFD or on a defined output.

Suction Pressure trend is continuously monitored to determine when to start a defrost. This decreases the total number of defrosts needed.  Monitored inputs, such as Suction Temperature or Pressure, Oil Pressure, LLS Temperature, etc. can be viewed in a table or graph.

Monitor mechanical failures for:

  • Compressor Overload
  • Condenser Overload
  • Oil Pressure
  • Low Suction Pressure
  • High Discharge
  • Crankcase Heater.
  • Just in time alerts and controls configurations that shut down compressors before mechanical failures
  • Remotely Monitor and Release the system after errors.
