ECM 51 Frame Commercial
Refrigeration Motors
EM&S manufactures an
ECM unit bearing construction
motor that can serve as a drop-in
replacement for the obsolete GE
55/44 frame ECM 1650 or 1850
rpm motor. This motor is available
in a 9 watt and a 16 watt version.
This promises substantial energy
savings and potentially fast pay-
back on the cost of conversion.
Features:
• Ultra high efficiency
• Improved reliability
• Enhanced airflow performance
• Energy savings of 66 percent
over a wide speed range
• Low operating temperature
• Lyall plug or EMF plug
• Accessories included with
each motor; (1) speed nut,
(1) resilient fan silencer,
(3) 8-36 mounting screws,
(1) rainshield
• Replaces GE ECM 55/44
frame motors
Specifications:
• Totally enclosed air over
• Unit bearing
• 1/4” - 20 Threaded shaft
• 60/50 Hertz
Evaporator/Condenser
The Unitronix Double Duty is an
electronically commutated motor
that brings outstanding energy
savings to the refrigeration
market in the form of a direct
drop-in replacement for
practically all unit bearing
motors. No additional labor or
sheet metal work is required to
replace an existing shaded pole
unit bearing motor with a
Unitronix Double Duty.
Heat in a refrigerated space has
always been a necessary evil in
the food marketing industry.
Lights, motors and defrost
heating elements are the culprits.
But, heat shortens food storage
life and adds to the load placed
on the refrigeration system. The
new Unitronix Double Duty
dramatically reduces (by as
much as 75%) the waste heat
generated by refrigerated case
evaporator motors.
Features:
• Special wide temperature range
lubrication system
• High capacity oil reservoir spiral
grooved shaft for efficient
distribution of oil to the
bearing surface
• Mounting hardware included
• Water shield included
• Tapped & Drilled Mounting Holes:
Universal Evaporator Mount
- Standard 3-Hole
- Custom 4-Hole Hussmann Style
Universal Condenser Mount
- Double Boss
Specifications:
• 1550 RPM standard
• Cast iron
• Unit bearing
• EMF P-2-1A lyall power plug
• 15” Leads
• UL file no. E128044
