The EC motor is an energy efficient option on Chandler Medium Profile evaporators. Available on all new equipment or as an easy-to-install, drop-in replacement aftermarket part from InterLink Commercial Refrigeration Parts. Because they re a drop-in replacement for existing PSC motors, installation is quick and easy. It s a high impact, quick payback solution for reducing costs and achieving green initiatives without replacing the entire system. EC motors by InterLink are up to 75% efficient - that s a 30-35% increase over permanent-split capacitor (PSC) motors. With all of this added efficiency, you can count on more energy savings and lower operational costs while taking a step in the right direction toward conserving our planet s resources.
