Is it a good idea to operate an electric motor in the hot, moist airstream of a cooling tower?
A. In this case, yes. The motor is TEAO (Totally Enclosed, Air Over) essentially sealed with a 40°C temperature rise design and a sealed Class “H” insulation. Additionally, when the motor is turned “OFF”, a DC trickle current is applied to keep the interior warm and condensation burned off, a feature that eliminates the need for internal space heaters. The motor casing also has generous cooling fins to dissipate heat. Inpro shaft seal with backup slinger helps protect from environment ingress. 100% grease fill eliminates voids and minimizes condensation damage as well as provides a grease dam assisting in sealing the system.
