The ECMTEK controller works in conjunction with 2 speed EC (electronically commutated) motors to maximize their efficiency and nearly double the energy savings provided by EC motors alone.

The EC Advanced Motor Controller functions by sensing the operational status of the cooling system, and controls the speed of the EC evaporator fans. When the thermostat is satisfied and the compressor cycles off, the ECMTEK controller will sense the compressor off cycle and will switch the motors to the slower speed.

It is a fact that all of the electrical power which is used by the fan motors ends up as heat inside the refrigerated space.

By operating the fans at a low speed when no cooling is called for, and at high speed only when the system is actively cooling the refrigerator, much less heat is introduced into the refrigerator.

Although this results in an additional savings in evaporator fan motor energy consumption, the reduction in fan motor heat generated causes a significant reduction in refrigeration operation, saving enough energy at the compressor to almost double the savings provided by the EC motors alone.

  • Technical Memo

    The ARC – Advanced Refrigeration Controller provides an advanced method for controlling and monitoring your coolers and freezers and allows you to maximize the amount of energy you save. These reductions in energy are made possible by the latest control algorithms available in modern refrigeration.

    Simply stated, the ARC is the best and most effective way to manage your refrigeration and its energy.


    ECMTEK replaces existing inefficient shaded pole and PCM motors with a more efficient option that delivers significant energy savings.
