Fibreglass Coatings

• Stop water and chemical leaks.
• Reduce bacteria growth.
• Extend the service life of your cooling towers for many years.
• RepelCoat is designed to withstand the harsh conditions of a cooling tower.
• Harsh – Chemical attack – High or low pH – Vibration – Excessive Joint Flexing
• Commercial Buildings – Industrial – Cold Storage – Food and Beverage
• Structural repairs and reinforcement

These systems are used for coating the interior of mild steel, stainless steel, and fiberglass cooling towers. Structural steel supports. Steel ductwork and fan discharges. The amazing thing about this system is the two-hour curing time between coats which is a great time saver for our clients. Submerged applications

RepelCoat RCR-200 for fiberglass is a two-stage coating system that is applied on top of the initial preparation process to the failing fiberglass and leaking seams / joints. The preparation involves grinding the fiberglass surface back to roughen the surface, repairing holes and cracks, and removing failed sealant on the surface.

• The first coat locks onto the roughened fiberglass surface. It is a flexible surface that moves with the cooling tower vibration and people walking on the surface.
• The second coat is our chemical resistant coating that can withstand all the terrible conditions that a cooling tower can attack.
• This is a bonded system that is flexible and extremely tough. If a tradesperson cuts it with a grinder or drills it, the damage is localized. This stops the RepelCoat system lifting off the fiberglass surface. The coating is easily repaired by a touch up coat to the affected area.

The cooling tower experts at FlowMatrix have 30 years of fiberglass cooling tower repair and coating experience.

FlowMatrix started repairing round fiberglass cooling towers in the 1990’s when they were the trend setting design to replace the old timber and steel cooling towers of the time. We carried out repairs of cracked fiberglass basins, water leaks from the casing or pipes, failed motors, and replaced sprinkler heads.

The 2000’s saw the modular square or rectangular fiberglass units introduced to comply with Australian Standards AS / NZS 3666 Part 1. Aquacool and Hydrothermal were the pace setter of that time so we started to repair these modular fiberglass cooling towers. New towers such as BAC Ultralight MSS, Evapco, Temcel TES TED, Superchill SC EWK, Sulzer, Shinwa, Marley, and Tower Thermal were introduced throughout in the 2010’s.

Some of these older fiberglass FRP cooling towers are now outdated or components are obsolete, so they need to be repaired, rebuilt, or replaced. FlowMatrix modernized old cooling towers by installing new Brentwood modular block fill pack, modern modular drift eliminators and FlowMatrix air intake splash louvers in stainless steel frames. We also have our trademarked coating system RepelCoat to coat fiberglass casing and panels to restore the surfaces, and to stop water leaks.

Please do not be fooled by anyone that advises you that a tube of sealant will fix your leaking cooling tower, as you will be disappointed when it leaks again within a few months or weeks. There is excessive vibration within a fiberglass cooling tower that is caused by the rotating fan and the pump that pushes water into and out of the cooling tower. The extreme vibration opens the seams by loosening the bolts and weakening the sealant. The water treatment chemicals break down the sealant overtime which causes the seams and joints to leak water and chemicals onto the ground and into the waterways. Units like BAC RCT and PCT units have hollow legs that leak and need to be repaired. In 2019 FlowMatrix developed the RepelCoat TM cooling tower coating system, and it works to stop cooling tower water and chemical leaks. Do it once and get it right.

A water leak may also not be a water leak from a basin or the casing. It may be a failed drift eliminator, a missing or damaged air seal, a faulty ball float valve, an overflow issue, faulty structural supports that are causing the fiberglass to crack and leak. Having FlowMatrix inspect our fiberglass cooling tower issues could provide you with multiple solutions at the one time.

RepelCoat is a registered trademark of FlowMatrix in Australia. Formed in 2018 RepelCoat coating products are designed to provide specialized coating systems for cooling tower installations, cooling tower repairs, water leak sealing, pipework, steel supports, plant room floors, roof surfaces under cooling towers, pipework penetrations through floors and roofs, Cool store panel sealing and grouting systems for concrete plinths, or hollow core filling.

The challenge with cooling tower related coating requirements is that the product selected must be able to withstand, chemical attack, high or low pH levels, corrosion, erosion from fast moving water and grit, vibration, excessive movement, foot traffic, and a variation of materials such as steel / copper / fiberglass / plastic.
