Cooling tower engineering
Fans, motors & gearboxes
Mechanical replacement, overhaul and alignment for cooling tower drive systems.
Treat the drive as one connected system.
The fan, motor, gearbox, couplings and driveshaft operate together. Replacing one item requires attention to the connected equipment, mounting points and alignment as well as the component itself.
ENG-TECH provides overhaul or replacement options for cooling tower mechanical equipment, including laser shaft alignment. Existing equipment details help establish suitable replacements and the extent of associated work.

Options & scope
Selected for your installation.
Fans & motors
Fan blades and hubs, plus replacement motors including single-speed, two-speed and variable-speed options where appropriate.
Gearboxes & driveshafts
Replacement or overhaul, couplings and flexible elements. Carbon-fibre driveshaft options can be considered for suitable applications.
Supports & alignment
Mechanical support steelwork, mounting arrangements and laser shaft alignment within the agreed installation scope.
Start with the nameplates and interfaces.
Speed, power, rotation, shaft dimensions, coupling details and mounting arrangements help identify the equipment. A photograph of the complete assembly is useful alongside nameplate images. Alignment and vibration-related observations can inform the assessment, but suitability needs confirmation against the tower and operating duty.

Planning your project
Questions worth asking.
A clearer brief helps us identify a practical next step.
Can the existing gearbox be overhauled?
Overhaul and replacement are both options. The condition and identification of the gearbox need assessment before the route is agreed.
Does replacement work include alignment?
Laser shaft alignment is part of the available service range. It should be included explicitly in the agreed work scope.
