Support Structures – Steel & Concrete

The entire lifespan of your cooling tower relies on the integrity of its support structures.

FlowMatrix specialises in high-performance coating systems designed to solve common issues affecting tower columns, beams, and basins. Our coatings eliminate corrosion, prevent leaks, and significantly extend the service life of your asset against harsh chemicals and constant vibration.

Steel and Concrete Coating Systems

Our coating systems provide a robust defence that achieves critical outcomes:

Extend Service Life: By protecting the underlying materials, we guarantee a significant extension of your cooling tower’s operational life for many years to come.
Eliminate Corrosion: We stop the destructive progression of rust and corrosion on steel, alloy, and concrete surfaces, maintaining the fundamental strength of the tower.
Prevent Leaks: Our coatings seal existing porosity and cracks, stopping water and hazardous chemical leaks to ensure environmental compliance and water conservation.

Built for the Harsh Environment

Our coating systems are engineered to withstand the worst conditions inside the tower, including:

Harsh Chemical Attack (including high or low pH levels)
Constant Vibration and Excessive Flexing

Stop Chemical Loss
Save Water
Clean Air
Save Energy

RepelCoat Coating System Range

RepelCoat offers a range of specialised solutions designed to meet these exact challenges:

RepelCoat Rapid RCR-200 / 300 / 400: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. These systems are also suited to submerged applications.
RepelCoat PUME-200:Membrane coating system for concrete, steel and cool store panels.
RepelCoat PV-300 / 400:These systems are used on pipework, vessels, tanks that are associated with non-submerged cooling towers or refrigeration systems.
RepelCoat Grout GSW-200:For sealing / repairing hollow cores in steel fibreglass or concrete.
RepelCoat MP-100:Submerged concrete resurfacing repair.

For the application of the RepelCoat systems our personnel are trained in using the correct PPE, ventilation procedures, the application of the products, and hazard control.

Key Outcomes & Benefits of RepelCoat Rapid RCR-200 / 300 / 400:

The RepelCoat Rapid RCR-200 / 300 / 400 series is essential for high-performance internal and external coating of cooling tower components. Suitable for mild steel, stainless steel, and fibreglass interiors, as well as structural supports and ductwork in submerged applications. The key benefit is the amazing two-hour curing time between coats, providing significant time savings and reducing critical maintenance downtime for our clients.

Rapid Repair and Application

Fast Curing: The “Rapid” feature allows for quicker turnaround times, minimising cooling tower downtime and returning essential equipment to service faster.
Versatile Substrates: Suitable for application on a variety of materials common in cooling systems, including steel and fibreglass.

Durability and Protection

Corrosion Elimination: Creates an impermeable barrier that stops steel corrosion and prevents its progression, significantly extending the life of metal components.
Chemical Resistance: Engineered to withstand the harsh chemical attack found in cooling towers, including exposure to high or low pH levels and constant chemical splash-out.
Physical Resilience: A tough coating that can endure the constant vibration, flexing, and movement inherent in an operating cooling tower.
Leak Prevention: Effectively stops water and chemical leaks by sealing damaged surfaces and existing porosity.

Lifecycle Extension

Repair and Extend: Used to repair heavily damaged fibreglass and other surfaces, allowing for the life expectancy of aging units and equipment to be significantly extended, making it far more cost-effective than full replacement.
