Choose the most energy-efficient motor available for evaporators.
The EC motor is an energy sufficient option on 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 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 system.
EC 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 resources.
