Larkin 25317501s Oem Ecm Refrigeration Unit Cooler Motor 1/4 Hp 208-230V 1175 Rpm Cw 1/2 Inch Shaft

Product Description

The Larkin 25317501s is an OEM electronically commutated motor (ECM) designed for use in Larkin refrigeration unit coolers. This motor delivers reliable, energy-efficient performance in commercial refrigeration applications where consistent airflow and temperature control are critical. HVAC and refrigeration technicians trust ECM technology for its superior efficiency compared to traditional PSC motors. The electronically commutated design allows the motor to adjust speed and power consumption based on load demand, reducing energy use and heat output inside the refrigerated space. This makes it a preferred choice for walk-in coolers, freezers, and other unit cooler assemblies found in food service, grocery, and cold storage facilities. The Larkin 25317501s runs at 1175 RPM with a clockwise rotation, making it a direct OEM replacement for compatible Larkin unit cooler systems. It operates on 208-230V power at 60Hz, which is the standard voltage range found in most commercial refrigeration installations across North America. The motor produces 1/4 horsepower and features a 1/2 inch shaft diameter for straightforward coupling to fan blades and impellers. Using an OEM replacement motor ensures proper fit, correct electrical characteristics, and the performance specifications the original equipment was designed around. Aftermarket substitutes can introduce mismatches in RPM, rotation direction, or shaft size that lead to premature failure or reduced system efficiency. Refrigeration technicians performing unit cooler motor replacements should verify rotation direction and shaft size before installation. This motor is also well-suited for preventive maintenance programs where aging PSC motors are being upgraded to ECM technology for energy savings.

• OEM ECM motor engineered specifically for Larkin refrigeration unit coolers
• Clockwise rotation at 1175 RPM with a 1/2 inch shaft diameter for direct replacement fit
• Operates on 208-230V at 60Hz — compatible with standard North American commercial power supplies
