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

Choose the most energy-efficient motor available for evaporators.
The EC motor is an Energy Solutions® option on new Bohn Medium Profile
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% efficient - that’s 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.

Features & Benefits
Cabinet

Coil

•
•
•
•

Schrader valve provided for suction pressure measurement
External equalizer connection
Heavy-guage textured aluminum cabinet
All electrical components factory wired to terminal board
and identified, making it easy to field wire the unit
• Sweat connections to reduce potential for leaks
• Internal panels are isolated for quiet operation
• 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)

• 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

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
• Thermally protected, lifetime-lubricated single phase
PSC motors

Factory-installed liquid line
solenoid wiring harness for
faster installation

Innovative Thermo-Flex™ coil

Options
• Totally enclosed single phase PSC motors available as an option for 208-230 and 460 voltages
• Unit Configurations: mounted components, pre-assembled, pre-charged and Beacon II™
- Units available with mounted TXV and mounted TXV / solenoid valve
- Pre-assembled units come with mounted TXV, liquid line solenoid valve and room thermostat
- Pre-charged units come with mounted TXV, liquid line solenoid valve, room thermostat and quick connect fittings
(limited availability)
- Room thermostat option mounted on the back of unit
- Beacon II units come with electronic expansion valves, pressure transducer, temperature sensors and Beacon control board
• Most models available with glycol circuiting (see glycol product brochure)
• Units available with stainless steel housing and drain pan
• Units available with copper fins. Air defrost units also available with polyester coated fins or various coil coatings options
• Units available with insulated drain pan
• Ship-loose air sock collar available
• Wire fan guards for air diffusion
• Adjustable defrost termination / fan delay thermostat
Bohn offers a five-year limited guarantee against leaks at tube sheets and center supports for all medium profile unit coolers

Air Throw*†

Fan Data
Diameter

* Standard molded fan guards allow for extended air throw; optional wire guards promote air diffusion
†
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 airflow values (Units with EC motors operating at 50 Hz will
not see a reduction in performance due to the electronic control of the motor)
