Mixed Flow Evaporative Fluid Coolers/Closed Cooling Tower
NWF Our NWF series closed cooling tower stands at the forefront of innovation with its cutting-edge composite flow cooling technology. It promises stable operation while championing energy efficiency and environmental sustainability. As the spray water cools the heat exchange coil, it then seamlessly flows into the cold water basin via the PVC heat exchange layer. This design not only effectively lowers the temperature within the tower but also ingeniously minimizes noise by preventing direct splashes into the basin.
High-Efficiency Mixed Flow Closed Circuit System
Operation
Experience exceptional cooling like never before with our advanced system. The fluid medium, requiring cooling, effortlessly traverses the highly efficient serpentine coil heat exchanger. It's complemented by a sophisticated external spray system that keeps the coil surface optimally moist for superior cooling. The cooled medium exchanges heat with spray water through a partition wall heat exchanger, forming a perfectly closed loop for unparalleled cooling. Low-temperature dry air enters from the sides, intermingling with the spray water's vertical flow to create a composite heat transfer driven by robust fans. As the air and spray water engage in thorough heat exchange, high-temperature saturated air is expelled, while the spray water undergoes a second round of heat transfer via a PVC layer before settling in a water collection basin. This process guarantees exceptional cooling efficiency and heat removal.
Advantage
> The innovative mixed flow close-loop circulation system ensures absolute purity of the media, significantly slashes maintenance costs, and meticulously conserves valuable water resources while delivering top-tier cooling performance.
> Our state-of-the-art combination of a stainless steel coil heat exchanger and PVC heat exchange layer presents a harmonious blend of efficiency and aesthetic appeal. This trailblazing design not only amplifies the heat transfer area but also heightens heat exchange efficiency, all while playing a crucial role in noise reduction.
> Featuring a pioneering single-side air intake design, the system remarkably reduces noise emissions at the rear, making it perfect for deployment in environments where noise sensitivity is a priority.
> The product features a compact, space-optimized structure, facilitating the seamless integration of multiple cooling towers in a confined space.
Features
COOLING TOWER PARTS
1. Axial Flow Fan
Our precision-engineered aluminum alloy axial flow fan ensures a harmonious blend of low noise, unwavering stability, and exceptional efficiency. Equipped with a motor graded at IP55 for protection and F for insulation, it promises a robust, secure, and reliable performance.
2. Advanced External Spray System
This sophisticated system sprays a fine mist of cooling water onto the heat exchange coil, maintaining a perpetually wet surface for unparalleled cooling efficiency.
3. Premium Stainless Steel Heat Exchange Coil
Designed for excellence, our stainless steel coils feature outstanding heat exchange efficiency and superior corrosion resistance. Their lightweight yet durable construction offers an extended lifespan, while their recyclable nature promotes sustainability and environmental friendliness.
4. Innovative MAH PVC Fill Film (Advanced PVC Heat Exchange Layer)
Boasting an innovative integrated design, our PVC filler heat exchange layer combines filler, air inlet grille, and drift eliminator for consistent air intake and minimized water drift loss. Optimal heat transfer performance is ensured by the ample heat exchange surface area, enhanced by its unique surface texture. For specific project needs, we offer upgrades to high-temperature materials.
5. Exclusive MBD PVC Drift Eliminator
Our specially designed drift eliminator for closed cooling towers masterfully extracts airborne water droplets with minimal wind resistance, achieving an extraordinary 99.99% capture rate to ensure superior heat transfer performance.
6. Precision Air Inlet Louver
Designed to facilitate the even intake of cool, dry air, our louver ensures optimal passage through the coil and PVC heat exchange layer while reducing sun exposure and inhibiting microbial growth.
7. Durable Heavy-Duty Construction
Crafted from high-quality Z700 galvanized steel, our frame and shell deliver robust corrosion resistance. For the most demanding environments, choose the optional SUS314/316 or NWN-Armour anti-corrosion coated steel for unparalleled protection.8. Convenient Access Door
