Experience the pinnacle of cooling technology with our Mixed Flow Evaporative Fluid Coolers/Closed Cooling Tower.
NWF The NWF series closed cooling tower is at the forefront of modern cooling solutions, utilizing advanced composite flow cooling technology to deliver a remarkably stable operation. It is a shining example of energy efficiency and environmental consciousness. As the spray water cools the heat exchange coil, it seamlessly flows into the cold water basin through a sophisticated PVC heat exchange layer. This process not only optimally reduces the internal tower temperature but also significantly diminishes noise levels by preventing direct impact of the spray water on the basin base.
High-Efficiency Mixed Flow Closed Circuit System
Operation
Within this state-of-the-art system, the fluid medium in need of cooling meanders through the high-performance serpentine coil heat exchanger. An incessant external spray system ensures the coil surface remains moist, promoting efficient cooling. This design facilitates a closed-loop system where the medium exchanges heat with the spray water via a partition wall heat exchanger. Cool, dry air is drawn into the tower laterally, intersecting vertically with the spray water flow to create a robust composite heat transfer, powered by fans. The thorough exchange of heat between air and spray water results in the expulsion of high-temperature saturated air outside the tower, while the spray water undertakes another round of heat transfer through the PVC heat exchange layer, cascading into a water collection basin to further enhance cooling efficiency.
Advantage
> The Mixed flow close-loop circulation system ensures the integrity of the medium, slashes maintenance costs, and advocates for water conservation while delivering unparalleled cooling performance.
> The seamless integration of a stainless steel coil heat exchanger with a PVC heat exchange layer offers not just superior efficiency but also an exquisite design. This pioneering approach enhances the heat transfer surface, boosts heat exchange efficacy, and contributes to an overall reduction in noise levels.
> The innovative single-side air intake design effectively curtails noise emissions at the tower's rear, making it perfectly suited for deployment in environments where noise sensitivity is a concern.
> The product stands out with its ingenious compact structure and space-efficient design,allowing for seamless integration and combination of multiple cooling towers in a space-optimized manner.
Features
COOLING TOWER PARTS
1. Axial Flow Fan
The aluminum alloy axial flow fan is engineered to deliver exceptionally low noise levels while maintaining remarkable stability and efficiency. Featuring a motor with an IP55 protection grade and F-rated insulation, this design ensures outstanding safety and reliability.
2. External Spray System
The system ingeniously sprays cool water onto the heat exchange coil, ensuring its surface remains continuously wetted for optimal cooling performance.
3. Stainless Steel Heat Exchange Coil
Featuring stainless steel coils, this component offers outstanding heat exchange efficiency and superior resistance to corrosion. Its lightweight construction contributes to an extended equipment lifespan, while its recyclability underscores its environmentally sustainable nature.
4. MAH PVC Fill Film ( PVC heat exchange layer)
Designed with an integrated filler, air inlet grille, and drift eliminator, the PVC filler heat exchange layer ensures consistent air intake and minimizes water drift loss. This design significantly enhances heat transfer performance, while its unique surface texture increases heat exchange surface area for optimal efficiency. The filler can also be upgraded with high-temperature materials to meet specific project conditions.
5. MBD PVC Drift Eliminator
This exclusive drift eliminator, tailored for closed cooling towers, excels at effectively capturing airborne water droplets with a 99.99% capture rate. It achieves this with minimal wind resistance, ensuring superior heat transfer performance.
6. Air Inlet Louver
It facilitates the even sucking in of cool, dry air through the coil and PVC heat exchange layer while limiting sun exposure and microbial growth for enhanced efficiency.
7. Heavy-duty construction
Built with a high-quality Z700 galvanized steel frame and shell,it offers exceptional corrosion resistance. For challenging environments, choose the optional SUS314/316 or NWN-Armour anti-corrosion coated steel for unparalleled protection.
8. Access Door
The access door leads to the tower's inner maintenance platform,
which includes a practical inspection platform within the cooling tower, enhancing the ease of conducting inspections and maintenance with convenience.
