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.
