Low Profile Unit Coolers - Commercial Refrigeration …

1 Low Profile unit CoolersTechnical GuideModels LCA | LCE | LCHLK-LOPTB | AUGUST 2018 Replaces LK-LOPTB | APRIL 20182 Choose the most energy-efficient motor available for evaporators. The EC motor is an energy sufficient option on Larkin Low 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 are a drop-in replacement for existing shaded pole and 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 motors by InterLink are up to 75% energy efficient - that s a 51-59% increase over shaded pole motors and 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 of ContentsNomenclature.
