MTE Corporation has released its Matrix Air EC motor filter which is designed to mitigate harmonics that are produced by electronically commutated motors (ECMs). 

This new solution is optimized for HVACR and data centre cooling applications and can also be used anywhere ECMs are installed such as conveyance systems, variable refrigeration flow equipment, and refrigerated displays.

ECMs combine the benefits of DC electric motors with integrated drives and are primarily used to control the speed of fans such as those found in data centre fan walls and air handling units.

However, because ECMs emulate variable frequency drives (VFDs), they produce damaging harmonics that degrade and "pollute" lineside power quality which causes nuisance tripping, equipment to overheat, and problems with electrical utilities.

MTE's Matrix Air resolves these harmonic issues to provide greater stability across fan speed ranges which allows ECMs to operate at full speed and higher efficiency.

MTE president, Ahsan Javed, said Matrix Air is producing ground-breaking results.

"EC motors are growing in adoption as applications demand higher efficiency and control. Our proprietary Matrix Air design is ideally suited to help these critical systems run cooler, smoother and without downtime,” he said.

“The benefits are tangible, with a large data centre customer now saving thousands on their electrical bills all while enhancing uptime and reliability."

“Matrix Air is based on MTE's patented Matrix AP Filter product line. As each application is unique in terms of fans, load, and other technical requirements, MTE designs a customized solution that meets all customer specifications.”

MTE's director of engineering, Todd Shudarek, said his staff take a hands on approach and work directly with customers and other engineers to gather the right information to design a solution that fits the application.

“We are currently working on multiple custom Matrix Air projects with customers,” he said.

“Matrix Air is 25 per cent smaller in size to competitive options. We developed Matrix Air to fit within already densely packed electronics cabinets. With limited space, it was imperative that we minimize the footprint.”
