Mixed Flow Evaporative Fluid Coolers/Closed Cooling Tower
NWF The NWF series closed cooling tower harnesses cutting-edge composite flow cooling technology, ensuring stable operation while being energy-efficient and eco-friendly. After the spray water cools the heat exchange coil, it seamlessly flows into the cold water basin via the PVC heat exchange layer. This process not only effectively reduces the tower's internal temperature but also significantly minimizes noise from water falling directly into the bottom basin.
High-Efficiency Mixed Flow Closed Circuit System
Operation
The fluid medium requiring cooling travels through our advanced serpentine coil heat exchanger. A continuously operating external spray system moistens the coil surface, enhancing cooling effectiveness. This setup allows the cooled medium to exchange heat with the spray water via a partition wall heat exchanger, creating a sealed loop for unparalleled cooling efficiency. Fresh, cool dry air enters the tower from the side and interacts optimally with the downward flow of spray water. This composite heat transfer is fan-driven, ensuring maximum efficiency. As the air and spray water exchange heat, hot, moisture-laden air exits the tower, while the spray water undergoes another heat exchange via a PVC layer, falling into a water collection basin, which efficiently dissipates heat for unmatched cooling performance.
Advantage
> The Mixed flow close-loop circulation system ensures the medium remains pure, slashing maintenance costs and conserving invaluable water resources all while delivering superior cooling.
> The innovative blend of a stainless steel coil heat exchanger and a PVC heat exchange layer is incredibly efficient and aesthetically pleasing. This avant-garde design maximizes heat transfer areas, boosts heat exchange efficiency, and aids in noise reduction.
> The streamlined single-side air intake design significantly reduces noise output at the tower's rear, making it perfect for noise-sensitive applications.
> The product boasts a sleek, compact structure and space-efficient design, enabling the integration of multiple cooling towers seamlessly.
Features
COOLING TOWER COMPONENTS
1. Axial Flow Fan
Our cutting-edge aluminum alloy axial flow fan operates with remarkable low noise, delivering unparalleled stability and efficiency. Engineered with a motor boasting a protection grade of IP55 and an insulation grade of F, it ensures extraordinary safety and unwavering reliability.
2. External Spray System
Ingeniously sprays cool water directly onto the heat exchange coil, continuously moisturizing its surface to achieve optimum cooling performance.
3. Stainless Steel Heat Exchange Coil
Crafted from premium stainless steel, these coils provide exceptional heat exchange efficiency and robust corrosion resistance. Their lightweight design prolongs equipment lifespan, while their recyclable nature makes them an eco-friendly choice.
4. MAH PVC Fill Film (PVC heat exchange layer)
Our state-of-the-art PVC filler heat exchange layer features an innovative design that integrates filler, air inlet grille, and drift eliminator. This ensures consistent air intake, drastically reducing water drift loss, and delivering unmatched heat transfer performance. The unique surface texture offers a substantial heat exchange surface area, enhancing overall efficiency. Additionally, the filler can be upgraded to high-temperature materials to meet specific project requirements.
5. MBD PVC Drift Eliminator
Custom-tailored for closed cooling towers, this unique drift eliminator expertly extracts airborne water droplets with minimal wind resistance. With an impressive capture rate of 99.99%, it ensures optimal heat transfer performance.
6. Air Inlet Louver
Designed to meticulously ensure the even suction of cool dry air, channeling it through the coil and PVC heat exchange layer while reducing sun exposure and inhibiting microbial growth.
7. Heavy-duty Construction
The robust Z700 galvanized steel frame and outer shell,deliver superior corrosion resistance. For environments facing extreme conditions, optional SUS314/316 or NWN-Armour anti-corrosion coated steel offers unparalleled protection.
8. Access Door
Facilitates entry to the cooling tower's inner maintenance platform through the access door.
Incorporating an inspection platform within the cooling tower significantly enhances the ease of performing inspections and maintenance tasks.
