Counter Flow Evaporative Fluid Coolers/ Newin closed type cooling tower
NWN - A symbol of unmatched excellence in cooling solutions.
Discover the NWN series counter flow closed type cooling tower, engineered for superior performance with its closed-loop design. This tower supports an efficient dry operation mode when winter arrives, eliminating the need for spray water. It elegantly steps in to replace chillers during the cold months, drastically slashing energy consumption and operating costs.
The sophisticated mechanism involves circulating the fluid medium that demands cooling through a high-efficiency serpentine heat exchanger. Meanwhile, the innovative external spray system persistently wets the coil surface, optimizing the cooling process. As a result, the cooled medium seamlessly traverses through the partition heat exchanger, where it encounters the spray water for an effective heat exchange.
Features
- Pure coil cooling system adeptly handles high-temperature water, delivering exceptional heat exchange efficiency.
- Innovatively designed closed loop system with a hygienic medium, minimizes scaling issues, and champions both energy and water conservation.
- Ingeniously compact structure, economically optimized space usage, facilitating seamless shipping and hassle-free installation.
COOLING TOWER PARTS
1. Axial Flow Fan
Harnessing the power of a specially crafted aluminum alloy axial flow fan, featuring a forward-type blade structure that minimizes wind resistance, culminates in enhanced airflow, reduced noise, and remarkable efficiency. The high-strength fan stack's streamlined design ensures uniform airflow through the fan inlet and outlet, dramatically minimizing energy usage. Fan motor's protection class: IP55, Insulation class: F class. Options available: Two-speed, VFD, or anti-explosion motor for tailored applications.
2. EVD PVC Drift Eliminator
Expertly captures airborne water droplets with minimal wind resistance and an astounding 99.99% capture rate, guaranteeing superior heat transfer performance.
3. Uniform Water Distribution
Employing strategically placed Three-splashed-Nozzles for even water distribution under low pressure flow; designed with a large caliber and three splash types to prevent blockages, enhance spray coverage, and ensure continuous and effective cooling tower performance.
4. Stainless Steel Heat Exchange Coil
Engineered for excellence, the stainless steel serpentine bending tube and robust framework of the heat exchange coil deliver outstanding thermal performance and optimal contact with spray water, achieving efficient heat exchange and cooling. The stainless steel pipes resist corrosion, are lightweight, and fully recyclable.
5. EVL Inlet Grille
Featuring a distinctive 3D stereo 45-degree ventilation channel, which dramatically enhances product rigidity and wind load resistance.
Effectively reduces noise and inhibits algae growth.
Boasts anti-corrosion features, UV resistance, making it maintenance-free.
6. Heavy-duty Construction
Constructed with premium Z700 galvanized steel frame and shell, offering superior resistance to corrosion. For challenging environments, choose the optional SUS314/316 or NWN-Armour anti-corrosion coated steel for unmatched protection.
