HIMMEL® Cooling tower gear units and HIMMEL® Cooling tower gear motors

HIMMEL®Cooling tower gear motors can be supplied as an integrated unit or with an attached IEC standard motor.

The gear motors you need are also available as ATEX variants upon request. Gears and motor are built into a single sturdy and well-designed unit. The gear housings are sturdy, vibration-damping and designed for continuous operation. Oil loss and ingress of dust is prevented by radial sealing rings with a dust gutter. All gear wheels are helically geared, polished and surface hardened. This guarantees smooth operation.

HIMMEL®Cooling tower gear motors are used to drive large fans for cooling industry water or for use in air conditioning systems.

HIMMEL®Cooling tower gear motors are helical gear motors with reinforced axial and radial bearings. They are fitted with a roof over the fan cover as standard and therefore protected from rain and other weather.
