NEWIN NWF Series Mixed Flow Closed Type Cooling Tower
NWF The NWF series closed cooling tower showcases cutting-edge composite flow cooling technology designed for unparalleled performance. It ensures remarkably stable operation, significantly saves energy, and maintains an environmentally friendly profile. Once the spray water successfully cools the innovative heat exchange coil, it elegantly flows into the cold water basin via the advanced PVC heat exchange layer. This process masterfully reduces the tower's internal temperature while ingeniously minimizing noise levels, often caused by the direct waterfall motion of spray water into the lower basin. Experience the future of cooling excellence with this sophisticated engineering marvel.
Product Description
High-Efficiency Mixed Flow Closed Circuit System
Operation
Experience unparalleled cooling efficiency with our Advanced Closed Type Cooling Tower. The cooling process begins as the fluid medium seamlessly flows through our state-of-the-art serpentine coil heat exchanger. A continuous external spray system envelops the coil, optimizing cooling by facilitating an impressive heat exchange process within the closed loop design. As low-temperature dry air enters laterally, it harmoniously intersects with the vertical flow of spray water, creating a powerful composite heat transfer driven by robust fans. After an exhaustive heat exchange, high-temperature saturated air is expelled, while the spray water undergoes a secondary phase through a premium PVC heat exchange layer, culminating in a water collection basin. This method not only enhances cooling but ensures consistent superior efficiency.
Advantage
> The Innovative mixed flow closed-loop circulation system ensures the purity of the medium, reducing maintenance costs significantly while conserving vital water resources through its efficient cooling operation.
> Our combination of a durable stainless steel coil heat exchanger with a high-performance PVC heat exchange layer not only stands out in efficiency but also exemplifies elegance. This forward-thinking design maximizes the heat transfer area, significantly boosts heat exchange efficiency, and effectively reduces operational noise.
> The innovative single-side air intake design minimizes noise emissions, making it perfectly suited for environments where noise reduction is essential.
> Enjoy the benefits of a compact structure and space-optimized design, which effortlessly allows for the integration of multiple cooling towers, amplifying your cooling capacity with unmatched ease.
Features
COOLING TOWER PARTS
1. Axial Flow Fan
Our aluminum alloy axial flow fan is engineered to deliver a harmonious blend of low noise and steadfast performance. With an IP55 protection grade and F-grade insulation, this motor stands as a beacon of safety and reliability, ensuring efficient and stable operation.
2. External Spray System
This system elegantly cascades cool water over the heat exchange coil, consistently wetting its surface to maximize cooling efficiency.
3. Stainless Steel Heat Exchange Coil
Crafted from stainless steel, these coils are a marvel of modern engineering. They offer unparalleled heat exchange efficiency, outstanding resistance to corrosion, and a lightweight design. Their durability ensures a prolonged equipment lifespan, and their recyclability underscores a commitment to environmental sustainability.
4. MAH PVC Fill Film (PVC heat exchange layer)
Introducing a revolutionary PVC filler heat exchange layer that integrates seamlessly with air inlet grilles and drift eliminators. This design guarantees a steady stream of air intake, dramatically reduces water drift loss, and optimizes heat transfer efficiency. The innovative surface texture amplifies the heat exchange area, further enhancing overall system efficiency. For projects requiring elevated performance, the filler can be upgraded to endure higher temperatures.
5. MBD PVC Drift Eliminator
Our exclusive drift eliminator for closed cooling towers excels in capturing airborne water droplets with utmost precision. Featuring minimal wind resistance and a capture rate of 99.99%, it ensures superior heat transfer performance, safeguarding efficiency at every turn.
6. Air Inlet Louver
Strategically designed to facilitate the uniform intake of cool, dry air, this louver optimizes air passage through the coil and PVC heat exchange layer. It effectively limits sun exposure and curtails microbial growth, ensuring longevity and performance.
7. Heavy-duty construction
Constructed with robust Z700 galvanized steel, the frame and shell are engineered for superior corrosion resistance. For environments with extreme conditions, the optional SUS314/316 or NWN-Armour anti-corrosion coatings offer unparalleled protection.offering corrosion resistance. For particularly harsh environments, the optional SUS314/316 or NWN-Armour anti-corrosion coated steel provides exceptional protection.
8. Access Door
Enter the inner maintenance platform of the tower through the access door, designed for user-friendly entry.
The presence of an inspection platform inside the cooling tower greatly simplifies the process of carrying out inspections and maintenance, enhancing accessibility and convenience.
