Description
These TEFC motors are built according to NEMA standard, and designed to operate with 100% of humidity in the most corrosive environments. All the line is certified for use with frequency inverter, and can operate in both the horizontal and vertical position. The Cooling Tower was tested according to the IEEE 112, method B, and it has efficiency values certified by UL (CSA C390). They ensure high efficiency levels with high torque, even at low speeds.
