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

Choose the most energy-ecient motor available for evaporators.

Nomenclature

The EC motor is an Energy Solutions® option on new Bohn Low Velocity
Center Mount evaporators. Available on all new equipment or as an easy­to-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% ecient - 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 eciency, 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.

Optional Liquid Line Bypass Kit For Hot Gas Defrost

The WKG may be eld piped for hot gas defrost using the optional bypass kit.

When compressor vapor, in reverse cycle defrosting, is directed back into the evaporator at the suction
connection, it condenses into liquid. The eld-installed liquid line bypass kit directs the condensed liquid
around the thermostatic expansion valve and back into the liquid line.

Bypass kits include bypass piping, check valve and instructions. Adjustable fan control is shipped loose
with hot gas units.
