NEWIN NWF Series Mixed Flow Closed Type Cooling Tower
NWF The NWF series closed cooling tower is a marvel of engineering, utilizing cutting-edge composite flow cooling technology. Experience stability, energy efficiency, and eco-friendliness like never before. As the spray water cools the heat exchange coil, it seamlessly transitions into the cold water basin via the PVC heat exchange layer. This innovative process not only drastically reduces the internal temperature of the tower but also significantly minimizes noise usually caused by the direct fall of spray water into the lower basin.
High-Efficiency Mixed Flow Closed Circuit System
Operation
Our advanced cooling system begins with the fluid medium circulating through the highly efficient serpentine coil heat exchanger. A continuous spray system delicately moistens the coil surface, setting the stage for optimal cooling. As the cooled medium exchanges heat with the spray water through a partition wall heat exchanger, a closed loop of supreme cooling efficiency is achieved. Fresh, low-temperature air enters from the side, intersecting vertically with the spray water flow, creating a dynamic composite heat transfer driven by powerful fans. After the air and spray water have fully exchanged heat, high-temperature saturated air exits the tower, while the spray water receives a further heat transfer via a PVC heat exchange layer before falling into the water collection basin. This double-layer process ensures unmatched cooling performance.
Advantage
> The Mixed flow close-loop circulation system ensures the medium remains pristine, reduces maintenance costs, and is a champion in water conservation. It excels in efficient cooling.
> The combination of a stainless steel coil heat exchanger and PVC heat exchange layer is a testament to both efficiency and sophistication. This forward-thinking design maximizes the heat transfer area, pushes the boundaries of heat exchange efficiency, and contributes to noise mitigation.
> The single-side air intake design reduces noise emissions at the rear of the tower, making it perfect for installations in noise-sensitive settings.
> The product has a compact structure and space-saving design, which facilitates the integration of multiple cooling towers seamlessly.
Features
COOLING TOWER PARTS
1. Axial Flow Fan
Crafted from premium aluminum alloy, the axial flow fan in this cooling tower excels in delivering low-noise performance, steadfast stability, and superb efficiency. Its motor is fortified with a protection grade of IP55 and an insulation grade of F, epitomizing the pinnacle of safety and reliability.
2. External Spray System
Ingeniously designed to spray cool water over the heat exchange coil, it perpetually wets the coil's surface, effectively harnessing the power of evaporation for optimal cooling.
3. Stainless Steel Heat Exchange Coil
Our stainless steel coils are paragons of heat exchange excellence, offering superior efficiency, unmatched corrosion resistance, and a lightweight design. They promise an elongated lifespan for the equipment and champion environmental sustainability with their recyclability.
4. MAH PVC Fill Film (PVC heat exchange layer)
This distinguished PVC filler layer is a marvel of integration, combining a filler, air inlet grille, and drift eliminator. It ensures steady air intake, dramatically reduces water drift loss, and optimizes heat transfer performance. The intricately textured surface amplifies the heat exchange area, boosting efficiency. For projects with unique demands, the filler is upgradable to high-temperature materials, ensuring seamless adaptability to any condition.
5. MBD PVC Drift Eliminator
Our proprietary drift eliminator, engineered specifically for closed cooling towers, excels at removing airborne water droplets with unparalleled efficiency. It features minimal wind resistance while achieving an astounding capture rate of 99.99%, ensuring superior heat transfer performance.
6. Air Inlet Louver
Meticulously designed to ensure the even suction and passage of cool, dry air through the coil and PVC heat exchange layer, this louver minimizes sun exposure and microbial growth, enhancing the system's longevity and efficiency.
7. Heavy-duty construction
The structure is fortified with a high-quality Z700 galvanized steel frame and shell,boasting impressive corrosion resistance. For extreme conditions, optional upgrades to SUS314/316 or NWN-Armour anti-corrosion coated steel offer unparalleled protection, ensuring durability and peace of mind.
8. Access Door
Effortless access to the tower's inner maintenance platform is facilitated through the access door,
providing enhanced convenience for routine inspections and maintenance within the cooling tower, ensuring seamless operation.
