Refrigeration Solutions

BRAND NEW for 2019!


We have finalized, tested, and rolled out our newest feature of Control.

The Gellert Refrigeration Controller (GRC) makes controlling your Gellert refrigeration equipment a *breeze*…..    It is installed directly inside the door of your condensing unit – and carries the following AWESOME FEATURES:

  • Has the ability to rotate between multiple compressors, allowing you to sidestep the risk of any “one compressor” getting overworked.
  • While running multiple compressors, if a single compressor fails, the other will continue working so you don’t have a complete shut-down.
  • Condenser fans can be rotated, increasing the life span of all motors.
  • 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.
  • The Suction Pressure trend is continuously monitored to determine when to start a defrost, which 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.
  • There is monitoring of mechanical failures for: Compressor Overload, Condenser Overload, Oil Pressure, Low Suction Pressure, High Discharge, and Crankcase Heater.
  • Software Failures can be set to shut compressors off “prior to” mechanical failures, to allow time to examine the system remotely and clear the error.
