Our direct drive motor and variable speed drive packages for industrial cooling replace
the gearbox, driveshaft and induction motor typically used in cooling towers. This
combination provides high torque and low speed required for these applications without
additional drivetrain components. This results in less parts, less maintenance, lower
noise and reduced risks.
Direct drive motor and VSD packages can be used either
in wet or dry cooling towers, air cooled condensers (ACC) of air cooled heat exchangers
(ACHE). Whether you are from power generation, district energy, metals
or food and beverage industry, our direct drive motor and drive packages are the
perfect solution for your needs in industrial cooling.
Reduce maintenance and improve reliability. With this package, you can remove the gearbox, gearbox cooling system, driveshaft, couplings and bearings. This means no more gearbox maintenance, no gearbox oil leaks, no cooling water contamination and no long lead times for replacement parts.
Same technology can be also offered in conventional, yet power dense, foot mounted designs that replaces the belt and sheave applications
Lowers vibration and system noise
Saves energy and eliminates startup current peaks and stresses from across-the-line startup. The drive smoothly accelerates and decelerates the fan to the speed needed, rather than running directly on line.
Anti-windmilling technology controls fan blades when the system is not operating
Simplified fan drivetrain alignment, only need to align the fan to the motor shaft, supported by a global service network that ensures local support, no matter where the motor and drive are installed.

Designed for outdoor duty to handle the extremes of 100% humidity and chemical environments
Prevents water ingress along the shaft
Motors are available with either foot or flange mount designs
Shaft height, diameter and flange mounting dimensions can be directly interchangeable with some existing cooling tower gearbox designs
High performance paint system and synthetic grease
Long bearing lifetime exceeding L-10 100,000 hours
For new or retrofit industrial cooling systems up to 650 rpm / 11,000 Nm
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

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 single drives and drive modules
