Frigitek Systems are available in single-phase and three-phase configurations, for both freezers and higher temperature systems. Installation can be done by any competent electrician. No modifications are made to the refrigerant system or the compressor system. Frigitek Controllers are not VFDs.
Single-Phase models cover 120 Volt, 208-240 Volt and 480 Volt power, at up to 25 Amp capacity.
Three-Phase models are available for voltages from 208 to 480 Volts. The modular design of the Three-Phase system allows one Controller to handle an unlimited number of evaporators. Individual evaporators must be less than 20 horsepower.
ECM models cover 120 Volt, and 208-240 Volt power. We now offer a line of ECM replacements for the older shaded-pole motors. These ECM systems include a special controller featuring the Frigitek two-speed concept.

Duty Cycle Analyzer (DCA)
The DCA is an electronic battery-operated datalogger. It may be used to determine the duty cycle of the compressor or of the evaporator sub-system in a refrigerator or freezer. This allows accurate analysis of the pre-Frigitek operation of the system, so that the Analysis Spreadsheet will be able to accurately predict the savings after the Frigitek is installed. It can be used with or without the Frigitek being in the system.
We do not offer the DCA for sale, but will occasionally lend one out, subject to availabilty.
Here is a description of the use of the DCA.
