We have made a commitment to customer needs, innovation and environmental stewardship and have dedicated
ourselves to delivering energy-ecient choices. PSC and EC motors will reduce costs, improve the bottom line and
enhance equipment performance and service life.

Choose the most energy-ecient motor available for evaporators.
The EC motor is an Energy Solutions® option on new Bohn Center Mount
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 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 system.
EC motors by InterLink are up to 75% ecient - 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 eciency, 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.
