Choose the most energy-ecient motor available for evaporators.
The EC motor is an Energy Solutions® option on new Bohn Low Prole
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.
