WEG’S Cooling Tower - NEMA Premium Efficiency motors meet or exceed all NEMA Premium and CEE requirements for energy efficiency. Cooling Tower – High Efficiency motors also meet or exceed CEE. These TEFC motors are built according to NEMA specifications and designed for operation in 100% humidity and the most corrosive environments. The entire line is certified Inverter Rated for use with a VFD. They are designed to operate in either horizontal or shaft up position. As with any other WEG motor, Cooling Tower motors are tested in accordance with IEEE 112, Method B, and their efficiency values are certified by UL Labs (CSA C390). Cooling Tower motors will meet will meet Design B torques, maintaining exceedingly high breakdown and locked rotor torque while providing the highest rated efficiency levels.
