Mechanical Drive Repairs & Replacement

FlowMatrix expertly performs mechanical drive repairs and replacements for cooling towers.

Their skilled technicians can efficiently diagnose issues, then safely remove and install new or refurbished components like fans, motors, shafts, and bearings.

No fan drive, no cooling.
That’s the reality.

A non-operational fan drive on your cooling tower means minimal to zero cooling capacity.

This isn’t just an inconvenience; it’s a critical failure with serious implications across various sectors:

  • Industrial Sites: Expect significant production loss due to the absence of essential cooling water for process lines.
  • Commercial Buildings: The entire air-conditioning system will shut down, leading to considerable discomfort and disruption for occupants.
  • Data Centres: Rooms will rapidly overheat, directly causing computer failures and potential data loss as air-conditioning becomes unavailable.
  • Healthcare Facilities: Critical areas like operating theatres will lose essential air-conditioning, posing severe risks.

Ensuring your fan drive is in optimal condition is paramount to avoiding costly downtime and maintaining continuous, efficient operations.

Repair and replacement

FlowMatrix service technicians are highly experienced to repair and replace cooling tower fan and motor drives that have failed or that are in a poor state. Our technicians are heights and confined spaced trained, skilled to setup lifting and rigging gear to safely remove old fans, motors, shafts, bearings, pulleys, belts, and install new.

Cooling tower fans are generally barrel / drum (centrifugal fans) or impellor type fans (axial fans). We have years of experience to select the correct fan drive replacement for your cooling tower by working out the design air flow, the static pressure drop, and the correct speed. The fans are factory built, pitched, and balanced so that can be sent to site and installed.

Larger fans can be CKD and sent to site for site assembly by our trained installers.

The shafts, bearing, pulleys, and belts are also selected to be suitable with cooling tower conditions.

Cooling tower motors must be modified and built for cooling tower conditions.

Motors are subjected to high water loading, high or low pH, and chemical attack.

The motors we supply are selected and modified with the correct sealing system installed and correct drainage holes drilled.

FlowMatrix unsure that the cooling tower motor we supply is correct, including the mounting, shaft suitability for the fan / impellor, and suitable for the motor mount.

Inspection and Maintenance

  • Cooling tower fan drive motors and fans are not parts that you can just buy off the shelf. Parts can take anywhere from 1 to 12 weeks to get in
  • Can you have your cooling tower offline for up to 12 weeks?
  • Older cooling towers could have obsolete parts that are not available from the original manufacturer as they have shut down or taken over.
  • Old low speed motors are expensive and difficult to obtain.
  • Prevention is always better than cure, and FlowMatrix’s engineering performance service is the protection you need to keep your cooling towers operating at their peak efficiency
  • FlowMatrix offer a full service, supply, installation, and maintenance

Cooling towers can make an ideal breeding ground for Legionella bacteria to grow. It is imperative that towers are regularly inspected to ensure all components are operating as designed.
