COOLING TOWER PARTS
1. Axial Flow Fan
Crafted specifically for cooling towers, our aluminum alloy axial flow fan features a forward-type blade structure for minimal wind resistance and maximum air volume. Enjoy low noise and exceptional performance with our high-efficiency design. The streamline high-strength fan stack ensures uniform airflow at the fan inlet and outlet, dramatically reducing energy consumption. The fan motor boasts a protection class of IP55 and an insulation class of F. Available options include two-speed, VFD, or anti-explosion motors.
2. EVD PVC Drift Eliminator
Achieve exceptional heat transfer with our highly efficient drift eliminator that captures 99.99% of airborne water droplets with minimal wind resistance.
3. Uniform Water Distribution
Our innovative Three-Splashed-Nozzles ensure uniform water distribution at low pressure, thanks to their large caliber and unique three-splashed design. This prevents blockages, enhances spray coverage, and guarantees continuous, effective cooling tower performance.
4. Stainless Steel Heat Exchange Coil
Utilizing high-grade stainless steel serpentine bending tubes, our heat exchange coil offers remarkable thermal performance and effective cooling through full contact with spray water. It is corrosion-resistant, lightweight, and recyclable.
5. EVL Inlet Grille
Featuring a special 3D stereo 45-degree ventilation channel, this component significantly enhances rigidity and wind load resistance for improved product stability.
Our design reduces noise levels and inhibits algae growth, ensuring a cleaner, quieter operation.
Engineered to be anti-corrosion, anti-ultraviolet, and maintenance-free for long-lasting performance.
6. Heavy-duty Construction
Built with Z700 galvanized steel, our frame and shell offer robust corrosion resistance. For extreme conditions, opt for SUS314/316 or NWN-Armour anti-corrosion coated steel for unmatched protection.
Options
