Cooling Tower and Air Handler Shaft Repairs using PES Products

PES-Solutions Cooling Tower Epoxy Coating Services

PES is licensed by the state of Texas to do work with cooling towers. We offer services to assist in maintaining your cooling tower, and ultimately expanding the life of the tower. We offer products such as PES 501 and PES 505 to seal leaks. In addition, we can apply our Anti-slip coating PES-2500 to the interior of your cooling tower to reduce slipping risks.

Here is an example of a cooling tower epoxy coating service we recently did for a customer in which we completed another cell in their 4-cell concrete cooling tower. In addition to applying our epoxy coatings to repair cracks, corners and 90° transitions, our team also applied our Anti-Slip PES-2500 this year.

Shaft Repairs – Using the Former (split sleeve) Technique

Shaft is damaged, disassembly is difficult or impractical. Repair in place is attractive. Remove old bearing and other obstructions. Prep the shaft with grinders. Leave surface as rough as possible.

Machine a split sleeve (can be made from any rigid material). The I/D of the sleeve is to be the same as the O/D of the shaft. 1/8” weep holes are drilled in the sleeve every 3 – 4 inches. Release agent is applied to sleeve. PES 101 Power Metal is applied to both shaft and sleeve and sleeve is clamped in place.

Once the PES 101 Power Metal material has cured (2 to 4 hours), the sleeve is removed. Parting lines and nubs from the weep holes are cleaned up with emery cloth and the shaft is ready for reassembly.
