Introducing the NEWIN NWF Series Mixed Flow Closed Type Cooling Tower - your ultimate solution for unparalleled industrial cooling efficiency!
NWF The NWF series closed cooling tower stands out with its cutting-edge composite flow cooling technology, ensuring stable and smooth operation while prioritizing energy efficiency and environmental friendliness. After the spray water effectively cools the heat exchange coil, it is expertly directed into the cold water basin via the PVC heat exchange layer. This process not only significantly lowers the temperature inside the tower but also remarkably minimizes noise that would typically result from water directly falling into the bottom basin.
Product Description
High-Efficiency Mixed Flow Closed Circuit System
Operation
The fluid medium requiring cooling flows through the state-of-the-art serpentine coil heat exchanger. A continuous and robust external spray system ensures the coil surface is effectively moistened, optimizing cooling. This configuration allows the cooled medium to seamlessly exchange heat with the spray water via a partition wall heat exchanger, establishing an efficient closed loop for unparalleled cooling. Low-temperature dry air enters the tower laterally, creating a dynamic vertical intersection with the spray water flow. This results in a powerful composite heat transfer, expertly driven by fans. After a thorough heat exchange, the high-temperature saturated air is efficiently expelled outside the tower. Simultaneously, the spray water experiences a secondary heat transfer through an advanced PVC heat exchange layer before gracefully descending into a water collection basin, effectively dissipating additional heat for exceptional cooling efficiency.
Advantage
> The ingeniously designed Mixed flow close-loop circulation system ensures the media remains pristine, significantly reducing maintenance costs, all while conserving valuable water resources and delivering highly efficient cooling.
> The perfect synergy of a stainless steel coil heat exchanger and PVC heat exchange layer is a marvel of efficiency and sophistication. This groundbreaking design not only maximizes the heat transfer area but also boosts heat exchange efficiency while contributing to a reduction in operational noise.
> The innovative single-side air intake design effectively minimizes noise emissions at the rear of the tower, making it ideal for deployment in environments where noise levels are a critical concern.
> The product boasts a sleek, compact structure and a space-efficient design, allowing for seamless integration of multiple cooling towers.
Features
COOLING TOWER PARTS
1. Axial Flow Fan
The aluminum alloy axial flow fan is a masterpiece of engineering, operating with remarkable low noise, stability, and efficiency. It is powered by a motor with an impressive protection grade of IP55 and an insulation grade of F, ensuring unparalleled safety and reliability for your industrial cooling needs.
2. External Spray System
Spraying cool water into the heat exchange coil is a critical function of this system. It continuously wets the coil's surface, ensuring maximum cooling efficiency and performance.
3. Stainless Steel Heat Exchange Coil
Our stainless steel coils are the epitome of advanced heat exchange technology, delivering exceptional efficiency and enhanced corrosion resistance. Their lightweight design contributes to a prolonged lifespan, and they are environmentally sustainable thanks to their recyclability.
4. MAH PVC Fill Film (PVC heat exchange layer)
The PVC filler heat exchange layer boasts an innovative design that integrates the filler, air inlet grille, and drift eliminator. This ensures consistent air intake and dramatically minimizes water drift loss, optimizing heat transfer performance. The uniquely textured surface offers an expansive heat exchange area, enhancing overall efficiency. For projects with specific requirements, the filler can be upgraded to high-temperature materials.
5. MBD PVC Drift Eliminator
Our exclusive drift eliminator is specifically crafted for closed cooling towers, efficiently extracting airborne water droplets with minimal wind resistance. It boasts a remarkable capture rate of 99.99%, ensuring optimal heat transfer performance for your system.
6. Air Inlet Louver
The air inlet louver ensures that cool dry air is evenly drawn in and passes seamlessly through the coil and PVC heat exchange layer, effectively limiting sun exposure and inhibiting microbial growth, thus maintaining a pristine environment within the system.
7. Heavy-duty construction
Our system features a high-quality Z700 galvanized steel frame and shell,crafted to offer superior corrosion resistance. For environments that pose extreme challenges, the optional SUS314/316 or NWN-Armour anti-corrosion coated steel provides unrivaled protection and durability.
8. Access Door
The access door provides entry to the tower's inner maintenance platform,
where you will find a conveniently placed inspection platform, enhancing ease of conducting thorough inspections and maintenance, ensuring the tower's longevity and uninterrupted performance.
