Product Description

Presenting the illustrious NEWIN NWF Series Mixed Flow Closed Type Cooling Tower, a marvel in cooling technology.

NWF This series of closed cooling towers employs cutting-edge composite flow cooling technology, ensuring stable operation, environmental benefits, and significant energy savings. After the spray water cools the heat exchange coil, it gracefully transitions into the cold water basin via the PVC heat exchange layer. This process expertly reduces the internal temperature while minimizing any noise from water impact, delivering a serene operation.

High-Efficiency Mixed Flow Closed Circuit System

Operation
Our cooling system channels the fluid medium through an efficient serpentine coil heat exchanger. An uninterrupted external spray system aids in moistening the coil surface, thereby enhancing the cooling process. This allows the cooled medium to seamlessly exchange heat with the spray water via a partition wall heat exchanger, creating a flawless closed loop. Cool air enters the tower laterally, engaging vertically with the spray water to form an impressive composite heat transfer mechanism driven by fans. Once complete, high-temperature saturated air exits the tower, while the spray water undergoes a second heat transfer through the PVC layer, ultimately collecting in the basin for exemplary cooling performance.

Advantage
> Unmatched The sophisticated mixed flow close-loop circulation system ensures media purity, significantly reduces maintenance costs, and conserves vital water resources all while delivering efficient cooling.
> The synergy of a robust stainless steel coil heat exchanger with a PVC heat exchange layer is both efficient and aesthetically pleasing. This groundbreaking design maximizes the heat transfer area, boosts heat exchange efficiency, and contributes to noise reduction.
> The pioneering single-side air intake design significantly cuts noise emissions at the rear of the tower, rendering it perfect for installations in environments sensitive to noise, ensuring tranquility.
> This exceptional product boasts a compact structure and space-conserving design, easily facilitating the integration of multiple cooling tower units into your system.

Features

COOLING TOWER PARTS

1. Axial Flow Fan
Our premium aluminum alloy axial flow fan is crafted to deliver unparalleled low noise, unwavering stability, and top-tier efficiency. Equipped with a robust motor, boasting a protection grade of IP55 and an insulation grade of F, it promises supreme safety and reliability.

2. External Spray System
This innovative system ensures continuous cooling by spraying water onto the heat exchange coil, consistently wetting its surface to maximize the cooling effect.

3. Stainless Steel Heat Exchange Coil
Our stainless steel coils are the epitome of excellence, offering superior heat exchange efficiency and exceptional corrosion resistance. They are lightweight, ensure a prolonged equipment lifespan, and are environmentally friendly due to their recyclability.

4. MAH PVC Fill Film (PVC heat exchange layer)
The MAH PVC fill film is a marvel of engineering, integrating filler, air inlet grille, and drift eliminator, ensuring consistent air intake, drastically reducing water drift loss, and optimizing heat transfer. Its unique texture maximizes the heat exchange surface, enhancing efficiency. Optionally, it can be upgraded to high-temperature materials to meet specific project needs.

5. MBD PVC Drift Eliminator
Our state-of-the-art drift eliminator, specifically designed for closed cooling towers, excels in removing airborne water droplets with minimal wind resistance and a remarkable capture rate of 99.99%, ensuring superior heat transfer performance.

6. Air Inlet Louver
Ingeniously designed to ensure cool, dry air is uniformly drawn in, guiding it through the coil and PVC heat exchange layer while effectively minimizing sun exposure and microbial growth.

7. Heavy-duty construction
Built with high-quality Z700 galvanized steel for the frame and shell,it offers excellent corrosion resistance. For especially challenging environments, optional SUS314/316 or NWN-Armour anti-corrosion coated steel provides unmatched protection.

8. Access Door
Facilitates entry into the tower's inner maintenance platform, ensuring convenient access for inspections and repairs. The presence of an inspection platform inside the cooling tower significantly enhances ease and efficiency when conducting inspections and maintenance.
