Electronically commutated (EC) fans provide a lower power, energy-efficient solution for many power-hungry AC applications. EC fans provide cooling solutions for a wide variety of refrigeration appliances, ventilation in range hoods and cooktops, and hot air flow for clothes dryers and dishwashers. Given the ever-increasing importance of energy conservation in today’s world, using advanced EC fans offers a significant improvement in power savings. In addition to cost savings from reduced power usage, EC fans provide reliable performance in rugged environments to extend operating life and lower maintenance cost. This durable performance is particularly important for applications involving explosive atmospheres or flammable gases. Implementing an IP68-ATEX EC fan into a design eliminates the possibility of an explosion or fire.
Powered by brushless DC motors, EC fans are up to 50% more efficient than AC motors due to their inherent design that uses permanent magnets to generate a secondary magnetic field rather than copper windings. This increased efficiency means that less energy is lost as heat while more energy is turned into power. EC fans incorporate electronics for voltage transformation that convert the incoming AC power to DC voltage needed by the motor. These electronics, which provide accurate and efficient EC motor control, also allow variable control of the EC fan speed, thereby improving its performance.
