New EC Motors for PRO3 Packaged Refrigeration Systems

Introducing the most-energy efficient motor available for packaged refrigeration systems. Choosing energy- efficient motors for your packaged systems can provide significant energy savings and lower operational costs. Additionally, because these motors can help reduce heat load (and system run-time), they can improve the reliability and longevity of refrigeration equipment.

Electronically Commutated (EC) motors even further improve energy efficiency and equipment reliability. EC motors by InterLink™ are up to 75% efficient – that’s a 51-59% increase over shaded pole motors and a 30-35% increase over PSC motors. As with PSC motors, you save money both directly from a decrease in motor watts and also from a reduction of heat gain into the refrigerated space.

Permanent Split Capacitor (PSC) motors can significantly lower your energy costs. PSC motors average 30-35% higher efficiency than shaded pole motors and offer dual energy savings by reducing motor watts and heat gain into the refrigerated space.
