NEWIN NWF Series Mixed Flow Closed Type Cooling Tower: A Revolution in Cooling Efficiency
NWF The NWF series closed cooling tower is an epitome of engineering excellence, incorporating state-of-the-art composite flow cooling technology. This tower offers unparalleled stability in operation, significantly reduces energy consumption, and is designed with a keen eye on eco-friendliness. After the spray water flawlessly cools the heat exchange coil, it seamlessly transitions into the cold water basin via the advanced PVC heat exchange layer. This sophisticated process not only ensures a substantial temperature drop within the tower but also elegantly minimizes noise by averting the impact of water directly falling into the bottom basin.
Product Description
Discover the cutting-edge High-Efficiency Mixed Flow Closed Circuit System
Operation
Within the Advanced Closed Circuit Cooling Tower, the fluid medium destined for cooling is expertly guided through our innovative serpentine coil heat exchanger. This masterfully designed system employs a continuous external spray mechanism to moisten the coil's surface, thereby optimizing the cooling process. Through a sophisticated partition wall heat exchanger, the cooled medium engages in a seamless heat exchange with the spray water, establishing a closed-loop system that ensures unparalleled cooling efficiency. Fresh, low-temperature dry air enters the tower laterally and dynamically interacts vertically with the spray water flow direction, enabling a superior composite heat transfer driven by high-performance fans. Once the air and spray water have completed their heat exchange, high-temperature saturated air is efficiently expelled outside the tower. Meanwhile, the spray water undergoes a crucial secondary heat transfer via a PVC heat exchange layer before descending into a water collection basin, effectively extracting more heat and delivering exceptional cooling performance.
Advantage
> The sophisticated Mixed Flow Close-Loop Circulation System ensures the purity of the media, significantly reducing maintenance costs and conserving invaluable water resources while simultaneously achieving highly efficient cooling.
> The harmonious combination of a robust stainless steel coil heat exchanger and an advanced PVC heat exchange layer delivers not only remarkable efficiency but also a sleek aesthetic. This pioneering design maximizes the heat transfer area, elevates heat exchange effectiveness, and even plays a role in diminishing noise pollution.
> The innovative single-side air intake design remarkably curbs noise emissions at the rear of the tower, making it the ideal choice for deployment in noise-sensitive environments.
> The product boasts a streamlined structure and space-efficient design, facilitating the 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.
