Two-speed operation is designed to match varying load profiles, delivering energy savings in cooling applications while maintaining performance at both high and low speeds. The 1760 r/min and 875 r/min outputs translate to a 20 HP / 5 HP capability, allowing precise control of condenser loads and chilled water circuits. Enclosed in a TEFC housing, the motor offers reliable operation in environments with dust and moisture exposure common to cooling towers and HVAC installations, reducing maintenance intervals. The 256T frame with a foot-mounted configuration provides compatibility with standard mechanical interfaces and supports straightforward retrofits into existing pump-and-manifold assemblies. Rated at 460 V, 60 Hz, the motor meets common North American plant electrical infrastructure, helping minimize panel upgrades and wiring complexity. UL/CSA certification and CSA|UR listing reinforce compliance with safety and installation codes, while the NEMA design B profile ensures predictable torque characteristics for fan-driven cooling systems. With a 40 °C ambient rating and F insulation, the unit is built for steady performance in modestly hot environments, offering dependable service life and predictable maintenance planning. Immediate stock across multiple warehouses, a 0 day lead time, and a 1 piece minimum order enable rapid procurement for project timelines and urgent repairs, reducing downtime and supporting lean maintenance strategies.
