Introducing the NEWIN NWF Series Mixed Flow Closed Type Cooling Tower: A marvel of engineering excellence, designed to redefine industry standards.
NWF The NWF series closed cooling tower integrates cutting-edge composite flow cooling technology to deliver unmatched performance. Experience seamless and stable operation that prioritizes energy efficiency and environmental sustainability. As the spray water descends and cools the advanced heat exchange coil, it flows gracefully into the cold water basin through the sophisticated PVC heat exchange layer. This innovative process not only optimizes temperature reduction within the tower but also significantly curtails the noise typically associated with water cascading directly into the bottom basin. Elevate your cooling tower experience with a solution that embodies precision, quiet operation, and eco-conscious design.
Product Description
High-Efficiency Mixed Flow Closed Circuit System
Operation
Experience unparalleled cooling efficiency with our Industrial Closed Type Cooling Tower. The fluid medium, needing cooling, is seamlessly guided through our high-performance serpentine coil heat exchanger. An innovative continuous external spray system diligently moistens the coil surface, optimizing the cooling process. The cooled medium effortlessly exchanges heat with the spray water through a sophisticated partition wall heat exchanger, forming an ultra-efficient closed loop. With low-temperature dry air smoothly entering laterally and crossing the spray water flow vertically, a composite heat transfer occurs, driven by powerful fans. As the air and spray water complete their heat exchange, high-temperature saturated air is swiftly discharged beyond the tower, while the spray water undergoes a secondary heat transfer via a cutting-edge PVC heat exchange layer. This strategic process, culminating in a water collection basin, ensures superior heat removal and exceptional cooling efficiency.
Advantage
> The Mixed flow close-loop circulation system ensures impeccable purity of the media, significantly reduces maintenance costs, and prioritizes the conservation of invaluable water resources while delivering superior cooling performance.
> The harmonious blend of a stainless steel coil heat exchanger with a PVC heat exchange layer is both highly efficient and aesthetically pleasing. This groundbreaking design amplifies the heat transfer area, elevates heat exchange efficiency, and subtly minimizes noise.
> The innovative single-side air intake design effectively diminishes noise emissions at the tower's rear, rendering it perfectly suited for environments sensitive to noise.
> The product boasts a compact structure and space-saving design, facilitating the seamless integration of multiple cooling towers.
Features
COOLING TOWER PARTS
1. Axial Flow Fan
The aluminum alloy axial flow fan ensures superior performance with its low noise output, steady operation, and remarkable efficiency. With a motor protected by an IP55 grade and insulated to an F grade, it guarantees unmatched safety and reliability for prolonged use.
2. External Spray System
This innovative system sprays cooling water directly onto the heat exchange coil, ensuring a continuously wetted surface for optimized cooling efficiency.
3. Stainless Steel Heat Exchange Coil
Crafted from stainless steel, these coils deliver exceptional heat exchange efficiency, enhanced resistance to corrosion, and a lightweight design. They extend equipment lifespan and are environmentally friendly due to their full recyclability.
4. MAH PVC Fill Film (PVC heat exchange layer)
The PVC filler heat exchange layer is ingeniously designed with integrated features like the filler, air inlet grille, and drift eliminator to maintain uniform airflow and minimize water drift loss, thus ensuring superior heat transfer. Its textured surface maximizes heat exchange area and efficiency. For projects with high-temperature demands, the filler can be upgraded to accommodate specific conditions.
5. MBD PVC Drift Eliminator
Our premium drift eliminator, specifically engineered for closed cooling towers, excels in removing airborne water droplets with minimal wind resistance and an impressive capture rate of 99.99%, ensuring peak heat transfer performance.
6. Air Inlet Louver
This louver ensures even and efficient intake of cool, dry air through the coil and PVC heat exchange layer, while limiting exposure to sunlight and reducing microbial growth.
7. Heavy-duty construction
Constructed with a robust Z700 galvanized steel frame and shell,this structure offers superior corrosion resistance. For extreme environments, optional SUS314/316 or NWN-Armour anti-corrosion coated steel is available to provide unmatched protection.
8. Access Door
This access door provides entry to the inner maintenance platform of the tower.
The presence of an inspection platform within the cooling tower offers enhanced ease and convenience for inspections and maintenance activities.
