MAXIMIZING EFFICIENCY WITH SMART COOLING

ECMTEK technology, acquired shortly after the release of EnerG², includes EC (electrically commutated) variable speed motors and controllers. These advanced ECMTEK motors replace existing single-speed shaded pole and PSC (permanent split capacitor) motors. Since EC motors are brushless, they produce significantly less heat compared to shaded pole or PSC motors, enhancing their efficiency. The ECMTEK Controller modulates motor speed based on temperature, moisture, and humidity, ensuring optimal performance.

ECMTEK retrofits are ideal for evaporators in walk-in coolers/freezers, as well as larger cold storage and food production facilities. Each existing motor is replaced with an EC motor and a controller for each evaporator. The larger the motor being replaced, the higher the energy savings and the shorter the return on investment (ROI).

ECMTEK offers a dual solution by combining EC evaporator fan motors and controllers, enabling variable speed operation with reduced wattage consumption. Traditional fan motors convert all electrical energy into heat, which is counterproductive in refrigerated environments. ECMTEK addresses this by operating fans at lower speeds and significantly reducing heat output when cooling is not required, thereby substantially lowering overall energy consumption.

7 REASONS TO CHOOSE ECMTEK

1. High Efficiency

A big advantage of ECM motors is that they are significantly more efficient when compared to AC motors. ECM motors maintain a high level (65 to 90 percent depending on size) of efficiency at a variety of speeds. This is not true for AC motors operated on variable frequency drives. As a result, ECMs are cost and energy efficient and can reduce operating costs. In most cases they use from less than one third to one half of the electricity used by traditional induction motors used in HVAC applications.

2. Ease of Control

ECMs are DC motors that function using a built-in inverter and a magnet rotor (no external VFD). The motor’s operation is simply controlled by software allowing customers to optimize and integrate the motor, fan and controller with the application. Features like data communications, constant volume control and variable speed control are simple to integrate.

3. Low Operating Temperatures

ECM motors’ high efficiency also means that the motors run “cool”, and dramatically reduce the amount of waste heat produced.

4. Quiet Operation

ECM motors are also quieter than traditional inefficient motors.

5. Extended Life

Motor life of the ECM is extended due to its low operating temperature operation. ECMs are also relatively low-maintenance; the use of true ball bearings reduces the need for oiling, and varied start-up speeds reduce stress on mounting hardware. Less components, less trouble.

6. Wider Operating Range

ECM motors also have a wider operating range than traditional induction motors, which means that one ECM motor can replace a number of induction motor models. In this way, the number of models required by a typical customer is significantly decreased, which decreases and simplifies inventory.
