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.
The EC motor is an Energy Solutions® option on new Bohn Medium Prole
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
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 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.

Liquid line solenoid wire harness is factory-installed for
quick installation
•
•
•
•
•
•
•
Drain Pan
Front hinged drain pan for easy access
Large diameter drain fitting (3/4" ID)
•
•
Motors
Motors plug into wiring harness for easier servicing
Single phase EC motors available factory-installed or as
a drop-in replacement through InterLink™ Commercial
Refrigeration Parts in 115 and 208-230 voltages

•
•
Coil
Patented Thermo-Flex™ coil design allows the coil to
“flex” during periods of defrost resulting in expansion of
the coil surface. By eliminating the possibility of wear at
critical stress areas, the integrity and longevity of the unit
are dramatically increased (Patent Number 5,584,340)
Coil heater slots have been enlarged for easier
installation and replacement
Electric defrost models have fixed defrost termination /
fan delay and heater limit thermostats
Reliable nickel steel alloy defrost heater elements
Heaters are coil face mounted for easy access

* Standard molded fan guards allow for extended air throw; optional wire guards promote air diusion
†Air throw data based on 12-ft. high ceilings with no obstructions where velocity drops to 50 FPM
‡For EC motors, use 60 Hz capacity and airow values (Units with EC motors operating at 50 Hz will
not see a reduction in performance due to the electronic control of the motor)
