What is Frigitek?

Frigitek™ is a series of patented energy saving control devices designed for walk-in or industrial refrigerators and freezers. The purpose of a refrigeration compressor and related equipment is to get heat out of the space. The fan motors often generate more than 30% of the heat in refrigerated spaces. Frigitek reduces this heat load by 75-80% by lowering the voltage to the evaporator fan motors when the box is not being actively cooled.

The result is a substantial reduction in operation costs. These reductions are further increased with the advent of the Frigitek EC Motor controller for motors up to 480V and 3.0 HP. Over ten years of extensive laboratory and field testing, and most importantly, Incentive Approval by LADWP, SCE, Anaheim Public Utilities, PG&E all most all other power companies. Listen to what our many satisfied customers have to say about the effectiveness of the Frigitek system.

Almost from the beginning, as the single-phase Frigiteks were being promoted, there were requests for a three-phase version from potential users, refrigeration contractors and service companies. After more than two years of research and design, the Three-Phase Frigitek was completed in 2005.

Frigitek Controller Systems are not VFDs making them ideally suited to reduce energy consumption without the requirements for more robust motors and free of causing available in single-phase and three-phase configurations, for both freezers and higher temperature system. No modifications are made to the refrigerant system or the compressor system.

Frigitek Overview

Our energy efficiency approach consists of changing out conventional motors in evaporator fans used in refrigeration systems, and replacing them with brushless DC motors and Frigitek™ Controllers, resulting in dramatic efficiency improvements.

We apply a clear-cut engineering solutions since efficiencies are simply derived from the difference between the energy performance of conventional motors and controls, and that of efficient Frigitek™ controllers operating EC motors that use internal electronic circuitry to convert AC to DC, and control speed and rotation.

Frigitek™ ECM I and ECM III Motor Controllers: The addition of either of these controllers to an evaporator will increase energy savings by about 50% over what EC motors alone will provide. Frigitek™ motor controllers function by sensing the operational status of the cooling system, and controlling the speed of the evaporator fans. By operating the fans at a low speed when no cooling is called for, the fans circulate about 40% as much as normal but will use only 10% as much energy, without impacting cooling requirements.
