EcoEX™ SureLine® FRP ODOUR CONTROL COVERS – ADVANCED CONTAINMENT. PROVEN PERFORMANCE. TRUSTED SOLUTION.
- VOC, Gas & Odour Containment: Effectively contain and control fugitive emissions and unpleasant odours, improving site safety and compliance.
- Durable & Load-Bearing: Engineered to withstand foot traffic and resist harsh chemical environments for superior longevity.
- Integrated Access & Safety Features: Optional access hatches and handrail systems can be seamlessly incorporated for easy inspection and maintenance access.
- Modular & Maintainable Design: Central panels can be removed without dismantling the entire cover system, reducing downtime and simplifying servicing.
- Lightweight & Corrosion Resistant: FRP offers a lightweight yet structurally strong alternative to steel or concrete, with superior corrosion resistance in aggressive environments.
EcoEX™ FRP BAFFLE WALLS – DURABLE, CORROSION-RESISTANT FLOW CONTROL SOLUTIONS
Baffle walls are strategically placed in tanks to direct water flow and minimise disturbance of sedimentation. By promoting even distribution, FRP baffle walls ensure optimal performance in clarifiers, aeration basins, and chlorine contact chambers. The non-corrosive nature of FRP means minimal maintenance and a longer service life compared to traditional materials like steel or concrete.
EcoEX™ baffle walls can also be customised to withstand sloshing loads in earthquake environments to minimise damage to existing concrete structures.
EcoEX™ FRP DUCTING – OPTIMAL VENTING FOR CORROSIVE GASES
FRP ducting is the ideal solution for venting corrosive gases in wastewater treatment plants. Highly resistant to chemicals like hydrogen sulphide and chlorine, FRP ducts offer long-lasting performance with minimal maintenance. Lightweight and easy to install, they reduce structural load and are perfect for both new builds and retrofits. Customisable in size and shape, FRP ducting ensures efficient air movement, odour control, and system safety. With superior corrosion resistance and durability, EcoEX™ FRP ducting is a smart, cost-effective choice for reliable air management in harsh wastewater environments.
EcoEX™ FRP STACKS – ENGINEERED FOR CORROSIVE ENVIRONMENTS AND LONG-TERM PERFORMANCE
Designed and engineered to withstand corrosive fumes, EcoEX™ FRP stacks offer unmatched durability in even the harshest air discharge environments. Unaffected by virtually all forms of bacteriological corrosion, these stacks are ideal for wastewater treatment plants, chemical processing facilities, and industrial exhaust systems.
