NWF Mixed Flow Closed Type Cooling Tower
The NWF series closed cooling tower employs efficient composite flow cooling technology, stable operation, energy saving and environmental friendly. Once the spray water has cooled the heat exchange coil, it is channeled into the cold water basin through the PVC heat exchange layer, effectively reducing the temperature within the tower and minimizing noise caused by straight falling spray water into the bottom basin.
High-Efficiency Mixed Flow Closed Circuit System
Operation
The fluid medium requiring cooling flows through the efficient serpentine coil heat exchanger. A continuous external spray system moistens the coil surface to facilitate cooling, allowing the cooled medium to exchange heat with the spray water through a partition wall heat exchanger, creating a closed loop for effective cooling. Low-temperature dry air enters the tower laterally and intersects vertically with the direction of the spray water flow, forming a composite heat transfer powered by fans. Once the air and spray water have fully exchanged heat, high-temperature saturated air is discharged outside of the tower while the spray water undergoes secondary heat transfer through a PVC heat exchange layer before falling into a water collection basin, effectively removing more heat for superior cooling efficiency.
Advantage
> The Mixed flow close-loop circulation system guarantees the purity of the media, diminishes expenses for maintenance, and conserves precious water resources while the efficient cooling.
> The combination of a stainless steel coil heat exchanger and PVC heat exchange layer is not only efficient, but also elegant. This innovative design maximizes the heat transfer area, enhances heat exchange efficiency, and even contributes to noise reduction.
> The single-side air intake design reduces noise emissions at the rear of the tower, making it ideal for use in noise-sensitive environments.
> The product has a compact structure and space-saving design, allowing for the combination of multiple cooling towers.
Main Parts
▷ The high-quality Z700 galvanized steel frame and shell, offering corrosion resistance. For particularly harsh environments, the optional SUS314/316 or NWN-Armour anti-corrosion coated steel provides exceptional protection.
▷ The aluminum alloy axial flow fan operates with low noise, stability, and efficiency. The motor is equipped with a protection grade of IP55 and an insulation grade of F, ensuring heightened safety and reliability.
▷ Stainless steel coils exhibit superior heat exchange efficiency, enhanced corrosion resistance, light weight, prolonged equipment lifespan, and are environmentally sustainable due to their recyclability.
▷ The PVC filler heat exchange layer utilizes an integrated design of filler, air inlet grille, and drift eliminator to guarantee consistent air intake, significantly minimize water drift loss, and ensure optimal heat transfer performance. Furthermore, the unique surface texture provides ample heat exchange surface area, thereby enhancing overall efficiency. The filler could be upgraded to high-temperature materials to align with the specific working conditions of the project.
▷ The exclusive drift eliminator designed for closed cooling towers is adept at efficiently extracting airborne water droplets, boasting minimal wind resistance and an impressive capture rate of 99.99%, thus guaranteeing optimal heat transfer performance.
▷
The presence of an inspection platform within the cooling tower enhances the convenience of conducting inspections and maintenance.
