Product description

The Nidec 3685368 (US Motors S59-628 / EC5407E) is a genuine OEM RESCUE ECM walk-in evaporator motor engineered to drive evaporator fan blades in walk-in coolers and freezers. This dual-voltage 115-230V motor operates without any connection change required, adjusting output between 1/25 HP and 1/15 HP with a corresponding RPM range of 1550-1625. The electronically commutated motor (ECM) design delivers up to 70% efficiency, significantly reducing energy consumption compared to older shaded-pole and PSC motors. Rated IP67, this motor is dust-tight with all-angle moisture protection and can withstand the demanding low-temperature, high-humidity environment inside a walk-in refrigeration unit, with an operating range of -40 degrees C to 55 degrees C. The stainless steel shaft and robust ball bearing system provide long service life, while the low-profile body style and standard 10-32 thread 3-stud mounting pattern (120 degrees apart) allow for a direct fit into existing evaporator fan housings.

Product highlights
