Variable Frequency Inverter Motor VFD Drives for Fans and Pumps

A cooling tower extracts heat from process cooling water. Common applications for cooling towers provide cooled water for air conditioning, manufacturing, and electric power generation.
A variable frequency drive can correctly identify the cooling tower fan rotation, slow the motor speed to zero (when opposite rotation is detected), and accelerate the fan in the correct direction. The VFD drive eliminates brakes, anti-ratcheting devices, and time delays. Running the fan slower, which raises tower and water temperatures, can prevent icing in cold weather. A VFD can reverse a cooling tower fan and keep the heat in the tower, if necessary. In warm weather, fans can be run faster, providing additional cooling capacity.

Application Challenges

  • Energy savings
  • Reduce maintenance requirements (personnel and equipment replacement costs)
  • Precisely control process water temperature stabilization

Features of P5 series cooling tower fan application



Dual digital tube

Double lines of LED display, monitoring 2 kinds of information meantime, like frequency, current, voltage, speed and PID data.

Smart restart

Instant power off continue running and speed tracking

S curve acceleration/deceleration mode

S curve acceleration/deceleration can reduce impact to the machine at start/stop time, and suitable for the start/stop process for loads of handling and transmission categories.

A variable-frequency drive (VFD) is a system for controlling the rotational speed of an alternating current (AC) electric motor by controlling the frequency of the electrical power supplied to the motor. A variable frequency drive is a specific type of adjustable-speed drive. Variable-frequency drives are also known as adjustable-frequency drives (AFD), variable-speed drives (VSD), AC drives, microdrives or inverter drives. Since the voltage is varied along with frequency, these are sometimes also called VVVF (variable voltage variable frequency) drives.
