Motor and drive cooling tower package for the Food and Beverage Industry

Simplicity. Reliability. Energy savings.
Everything counts.

What’s at stake when your cooling towers break down, or need maintenance? For food and beverage facilities, its more than the comfort of employees and equipment, the loss of production or the wait for and cost of replacement parts. It could mean the loss of raw ingredients used in food production. ABB’s direct drive motor cooling tower solution removes the cost, maintenance and worry associated with traditional gearbox or belted solutions. The fan couples directly to the motor and is controlled by an AC drive to provide optimal speed and cooling tower performance that runs quieter with reduced energy consumption.

The direct drive motor results in 20% or more energy efficient operation, depending on operation.

The direct drive motor is controlled by an AC drive that allows soft starts, resulting in a reduction in system stress and energy savings.

Direct drive cooling tower motor and drive benefits

Less parts, less maintenance, reduced risks

  • Eliminate the need for gearbox, gearbox cooling system, driveshaft, couplings and bearings. This reduces maintenance and offers improved reliability.
  • Reduce maintenance up to 90% . The direct drive motor could result in up to 90% or more less maintenance, depending on retrofit
  • Lower vibration and system noise. The direct drive motor results in 5 dB(A) or more noise reduction in operation, depending on retrofit
  • Save energy and eliminate startup current peaks and stresses from across-the-line startup
  • Increase safety due to removal of rotating equipment

Direct drive cooling tower RPM AC permanent magnet motor

  • Designed for outdoor duty to handle the extremes of 100% humidity
  • Prevents water ingress along the shaft
  • Motors are available with either foot or flange mount designs
  • High performance paint system and synthetic grease
  • Bearing lifetime exceeding L-10 100,000 hours for increased reliability
  • For new or retrofit industrial cooling systems up to 650 rpm / 11,000 Nm

Motor features

  • Vibration pad standard for FL58XX frame motors and optional on smaller motors 
  • Thermostats are standard on all motors. Their connection is required to validate the motor's warranty. 
  • Winding stator RTDs are standard on FL58XX frame motors and optional for smaller motors
  • Water ingress along the shaft is prevented with the slinger over Inpro seal for FL44XX and FL58XX and with V-ring slinger on smaller motors
  • Multiple bolt circles on the N-end shield for easy replacement installations

ACS880 industrial drive

  • Easy to configure, simple parameter setup
  • Trickle current function keeps the motor warm and dry, preventing condensation
  • Prevents fan from windmilling when not running
  • Sensorless permanent magnet motor control built-in - no encoders or resolvers needed
  • Built-in deicing function keeps fan blades ready for operation
  • The drive adjusts the motor speed to match the process demand, saving energy and lowering wear and tear versus direct-on-line operation
  • Cooling tower control program is available for industrial ACS880-01 single drives and ACS880-04 drive modules
