PACKAGED REFRIGERATION SYSTEMS

Introducing the most-energy ecient motor available for packaged refrigeration systems. Choosing energy-
ecient motors for your packaged systems can provide signicant 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 eciency and equipment reliability. EC
motors by InterLink™ are up to 75% ecient – 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 signicantly lower your energy costs. PSC motors average 30-35%
higher eciency than shaded pole motors and oer dual energy savings by reducing motor watts and heat gain
into the refrigerated space.
Savings are calculated using a cost of $.09/kWh
