Product Description

Introducing the remarkable NEWIN NWF Series Mixed Flow Closed Type Cooling Tower, a pinnacle of industrial cooling design.

NWF This series of closed cooling towers integrates cutting-edge composite flow cooling technology to ensure stable operation while promoting energy efficiency and environmental sustainability. After the spray water cools the heat exchange coil, it flows into the cold water basin via a PVC heat exchange layer, which significantly lowers the tower's internal temperature and minimizes noise typically generated by water falling directly into the basin.

Unparalleled High-Efficiency Mixed Flow Closed Circuit System

Seamless Operation
The fluid medium that requires cooling traverses a highly efficient serpentine coil heat exchanger. A perpetual external spray system keeps the coil surface wet, facilitating uninterrupted cooling. This allows the cooled medium to transfer heat with the spray water through a partition wall heat exchanger, establishing a closed loop for optimal cooling. Fresh, low-temperature dry air enters the tower laterally and crosses vertically with the spray water's flow, creating a composite heat transfer driven by powerful fans. Post heat exchange, the high-temperature saturated air exits the tower as the spray water undergoes a secondary heat transfer within a PVC heat exchange layer before settling into a water collection basin, effectively enhancing cooling efficiency to new heights.

Distinctive Advantages
> The Innovative Mixed Flow Closed-Loop Circulation System ensures the purity of the media, substantially reduces maintenance costs, and conserves valuable water resources, while ensuring exceptional cooling performance.
> The sophisticated combination of a stainless steel coil heat exchanger and a PVC heat exchange layer not only offers exceptional efficiency but also exudes elegance. This forward-thinking design maximizes heat transfer areas, boosts heat exchange efficiency, and even helps to reduce noise pollution.
> The ingenious single-side air intake design effectively reduces noise emissions at the rear of the tower, rendering it perfectly suited for noise-sensitive environments.
> The product boasts a compact and space-efficient design,enabling seamless integration of multiple cooling towers.

Features

COOLING TOWER PARTS

1. Axial Flow Fan
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.

2. External Spray System
Spray cool water into heat exchange coil,continuously wets the surface of the coil for cooling.

3. Stainless Steel Heat Exchange Coil
Stainless steel coils exhibit superior heat exchange efficiency, enhanced corrosion resistance, light weight, prolonged equipment lifespan, and are environmentally sustainable due to their recyclability.

4. MAH PVC Fill Film ( PVC heat exchange layer)
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.

5. MBD PVC Drift Eliminator
The exclusive drift eliminatordesigned 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.

6. Air Inlet Louver
Ensure cool dry air evenly sucked in and passed through the coil and the PVC heat exchange layer, Limiting sun exposure and microbial growth.

7. Heavy-duty construction
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.

8. Access Door
Into the tower inner maintenance platform through the access door. The presence of an inspection platform within the cooling tower enhances the convenience of conducting inspections and maintenance.
