NEWIN NWF Series Mixed Flow Closed Type Cooling Tower
NWF The NWF series closed cooling tower from Newin (Guangdong) Machinery Co., Ltd. ingeniously incorporates advanced composite flow cooling technology. Its design assures stable performance while promoting energy efficiency and environmental sustainability. Once the spray water efficiently cools the heat exchange coil, it seamlessly flows into the cold water basin through a sophisticated PVC heat exchange layer. This intelligent process not only significantly reduces the internal temperature of the tower but also expertly minimizes the noise generally caused by water directly falling into the bottom basin.
Product Description
High-Efficiency Mixed Flow Closed Circuit System
Operation
Experience the pinnacle of cooling technology with our Advanced Closed Type Cooling Tower. The fluid medium that requires cooling is channeled through an ingeniously designed serpentine coil heat exchanger. A perpetual external spray system envelops the coil, optimizing the cooling process. This allows the cooled medium to seamlessly exchange heat with the spray water through an efficient partition wall heat exchanger, crafting a closed loop that ensures outstanding cooling performance. Crisp, low-temperature dry air enters the tower laterally, harmoniously intersecting with the vertical spray water flow, creating a composite heat transfer system energized by powerful fans. Once the air and spray water have fully exchanged their thermal energy, heated, saturated air exits the tower, while the spray water undergoes a secondary heat transfer in a sophisticated PVC heat exchange layer, before cascading into a water collection basin. This intelligent design significantly elevates cooling efficiency by effectively removing excess heat.
Advantage
> The Mixed flow close-loop circulation system ensures the purity of the media, drastically reduces maintenance costs, and smartly conserves valuable water resources, all while delivering unparalleled efficient cooling.
> The synergy of a stainless steel coil heat exchanger with a PVC heat exchange layer is not just efficient, but also elegantly designed. This pioneering innovation maximizes the heat transfer surface area, significantly boosts heat exchange efficiency, and contributes to a quieter operation.
> The innovative single-side air intake design minimizes noise emissions at the rear of the tower, making it perfectly suited for deployment in noise-sensitive settings.
> The product boasts a compact structure and space-saving design,enabling the seamless integration of multiple cooling towers, enhancing system versatility.
Features
COOLING TOWER PARTS
1. Axial Flow Fan
The aluminum alloy axial flow fan is designed to operate with exceptional low noise, delivering outstanding stability and efficiency. With a motor protected by a high-grade IP55 and insulated to grade F standards, it ensures unparalleled safety and reliability in all operations.
2. External Spray System
The sophisticated external spray system effectively cools by dispersing water onto the heat exchange coil, continuously maintaining a wet surface for optimized cooling performance.
3. Stainless Steel Heat Exchange Coil
Our stainless steel coils are engineered to provide top-tier heat exchange efficiency. They boast enhanced corrosion resistance, are lightweight, and significantly extend the lifespan of the equipment. Their eco-friendly construction allows for complete recyclability, contributing to sustainable practices.
4. MAH PVC Fill Film (PVC heat exchange layer)
The PVC filler heat exchange layer is meticulously crafted with an integrated design, combining a filler, air inlet grille, and drift eliminator. This ensures a steady air intake, drastically reducing water drift loss and maximizing heat transfer efficiency. Its unique surface texture offers a substantial heat exchange surface area, elevating overall performance. For projects with specific needs, the filler can be upgraded to withstand higher temperatures.
5. MBD PVC Drift Eliminator
Specifically engineered for closed cooling towers, our exclusive drift eliminator excels at removing airborne water droplets with minimal wind resistance and an impressive 99.99% capture efficiency, consistently ensuring superior heat transfer performance.
6. Air Inlet Louver
The air inlet louver is designed to ensure uniform distribution of cool, dry air flow through the coil and PVC heat exchange layer, effectively reducing sun exposure and inhibiting microbial growth.
7. Heavy-duty Construction
Constructed with premium Z700 galvanized steel frame and casing,this structure offers excellent corrosion resistance. For the harshest environments, opt for SUS314/316 or NWN-Armour anti-corrosion coated steel to ensure exceptional durability and protection.
8. Access Door
Provides convenient entry to the inner maintenance platform through the access door.
The inspection platform integrated within the cooling tower facilitates seamless inspections and maintenance, enhancing operational convenience and efficiency.
