Cooling tower fan motor specification.
The tefc totally enclosed fan cooled motor is protected from water and debris reducing maintenance requirements.
Cooling tower duty motor overview cooling tower duty.
Cooling tower duty motors in marley products are built according to nema standards and designed to withstand exposure to hot moist cooling tower conditions.
Additionally to support long service life the motor s interior is fan cooled and coated with epoxy for maximum protection from heat moisture and corrosion.
These motors are designed to operate in 100 humidity.
These motors are perfect for operating inside the harsh cooling tower environment in direct contact with saturated moist air.
Typical installation of bac impervix fan motor inside cooling tower.
These motors can be operated shaft up down or horizontal.
The motor speed is typically 1 800 rpm s.
Cooling tower motors power the fans in cooling towers.
Fan speeds are much slower and are determined by the diameter of the blades to keep the blade tip subsonic typically around 90 to 230 rpm s.
Bac sets the standard with the latest generation impervix cooling tower fan motors.
They feature anti corrosion coating along with v ring and umbrella seals on both end shields to help to keep water out and protect the motor bearings from moisture.
The mechanical components of a cooling tower fan are made up of motor gearbox drive shaft disc couplings and fan impeller.
