Introducing the NEWIN NWF Series Mixed Flow Closed Type Cooling Tower that sets a new standard in cooling solutions.
NWF The NWF series closed cooling tower utilizes a cutting-edge composite flow cooling technology that ensures stable operation while being energy-efficient and environmentally harmonious. As the spray water cools the heat exchange coil, it gracefully cascades into the cold water basin via the advanced PVC heat exchange layer. This innovative design not only effectively lowers the temperature within the tower but also significantly diminishes noise levels by preventing the direct splash of water into the bottom basin, ensuring a quieter and more serene operation.
Product Description
High-Efficiency Mixed Flow Closed Circuit System
Operation
The fluid medium requiring cooling flows seamlessly through the remarkably efficient serpentine coil heat exchanger. Our continuous external spray system drenches the coil surface, ensuring optimal cooling conditions. This ingenious process allows the cooled medium to transfer heat with the spray water via a partition wall heat exchanger, creating a flawlessly closed loop for unmatched cooling. Crisp, low-temperature dry air enters the tower laterally and intersects vertically with the spray water flow, orchestrating a composite heat transfer driven by powerful fans. Once the air and spray water consummate their heat exchange, high-temperature saturated air is expelled from the tower, while the spray water experiences a secondary heat transfer through a sophisticated PVC heat exchange layer before gently descending into a water collection basin, ensuring exceptional heat removal and superior cooling efficiency.
Advantage
> The Mixed flow close-loop circulation system ensures the purity of the media, significantly reduces maintenance costs, and prudently conserves valuable water resources , all while delivering unparalleled cooling efficiency.
> The harmonious blend of a stainless steel coil heat exchanger and an advanced PVC heat exchange layer is not only highly efficient but also exudes elegance. This cutting-edge design maximizes the heat transfer area, boosting heat exchange efficiency, and even aids in noise reduction.
> The ingenious single-side air intake design minimizes noise emissions at the rear of the tower, rendering it perfect for deployment in noise-sensitive environments.
> The product boasts a compact structure and space-efficient design, enabling the seamless integration of multiple cooling towers.
Features
COOLING TOWER PARTS
1. Axial Flow Fan
Crafted from high-grade aluminum alloy, our axial flow fan operates with impeccable low noise levels, stability, and efficiency. Built to last, the motor boasts a robust IP55 protection grade and F-grade insulation, ensuring maximum safety and unwavering reliability.
2. External Spray System
Ingeniously spray cool water onto the heat exchange coil, continuously wetting its surface to maintain optimal cooling efficiency.
3. Stainless Steel Heat Exchange Coil
Our stainless steel heat exchange coils are engineered for outstanding heat transfer efficiency. They offer remarkable corrosion resistance, a lightweight design that extends the equipment's lifespan, and an eco-friendly advantage due to their recyclability.
4. MAH PVC Fill Film (PVC heat exchange layer)
The advanced PVC filler heat exchange layer features an all-in-one design, integrating filler, air inlet grille, and drift eliminator. This design assures consistent air intake and drastically reduces water drift loss, achieving top-notch heat transfer performance. The innovative surface texture amplifies the heat exchange area, enhancing overall system efficiency. For projects with specific needs, the filler can be upgraded to high-temperature materials.
5. MBD PVC Drift Eliminator
Our exclusive drift eliminator, crafted for closed cooling towers, excels in efficiently collecting airborne water droplets. It offers minimal wind resistance and an exceptional capture rate of 99.99%, ensuring optimal heat transfer efficiency.
6. Air Inlet Louver
Designed to ensure even suction of cool, dry air, which is seamlessly passed through the coil and PVC heat exchange layer. This process limits sun exposure and curbs microbial growth, safeguarding the system's integrity.
7. Heavy-duty construction
Built with superior Z700 galvanized steel for the frame and shell,providing exceptional corrosion resistance. For extreme environments, opt for SUS314/316 or NWN-Armour anti-corrosion coated steel, offering unparalleled protection.
8. Access Door
Conveniently enter the tower's inner maintenance platform through the access door.
The presence of an inspection platform inside the cooling tower enhances ease of conducting thorough inspections and maintenance, ensuring the system's smooth operation and longevity.
