Introducing the exceptional NEWIN NWF Series Mixed Flow Closed Type Cooling Tower, where innovation meets efficiency to deliver superior cooling performance.
NWF The NWF series closed cooling tower stands out by utilizing advanced composite flow cooling technology. This ensures not only stable operation but also significant energy savings while being environmentally friendly. As the spray water cools the heat exchange coil, it seamlessly transitions into the cold water basin through a sophisticated PVC heat exchange layer. This mechanism not only enhances cooling efficiency but also significantly reduces noise, often associated with direct water splashes at the base. Experience quieter and more efficient cooling, designed for superior performance and environmental consciousness.
Product Description
High-Efficiency Mixed Flow Closed Circuit System
Operation
Experience unparalleled cooling performance with our Wet Coil Closed Type Cooling Tower. The precision-engineered serpentine coil heat exchanger ensures your fluid medium is meticulously cooled. Our continuous external spray system envelopes the coil, optimizing heat transfer processes. This creates a seamless closed-loop mechanism, where low-temperature dry air enters laterally, ingeniously intersecting with the vertical spray water flow. As fans drive this complex composite heat transfer, high-temperature saturated air is efficiently expelled, while the spray water, through an innovative PVC heat exchange layer, undergoes a secondary heat transfer, cascading into the water collection basin. This cycle not only boosts cooling performance but also ensures superior energy efficiency for all your cooling needs.
Advantage
> The Mixed flow close-loop circulation system ensures pristine media purity, significantly reducing maintenance costs and conserving valuable water resources, all while providing excellent cooling. Our system is engineered for superior cooling performance.
> Combining the robustness of a stainless steel coil heat exchanger with the efficiency of a PVC heat exchange layer results in a powerful yet elegant assembly. This innovative approach not only maximizes the heat transfer area but also amplifies efficiency and minimizes noise output.
> The unique single-side air intake design significantly minimizes noise emissions at the rear of the tower, making it perfectly suited for noise-sensitive locales, where peace and quiet are paramount.
> The product boasts a compact structure and a space-efficient design, facilitating the seamless integration of multiple cooling towers, optimizing space without sacrificing performance.
Features
COOLING TOWER PARTS
1. Axial Flow Fan
Crafted from aluminum alloy, the axial flow fan operates with a symphony of low noise, superior stability, and unmatched efficiency. The motor, fortified with an IP55 protection grade and an F insulation grade, assures an elevated standard of safety and unwavering reliability.
2. External Spray System
A meticulously designed spray system that blankets the heat exchange coil in a continuous cascade of cool water, ensuring the outer surface remains optimally wet for superior cooling performance.
3. Stainless Steel Heat Exchange Coil
Our stainless steel coils are the epitome of advanced design, offering extraordinary heat exchange efficiency and unparalleled corrosion resistance. Lightweight yet robust, these coils extend equipment lifespan and are ecologically friendly due to their recyclable nature.
4. MAH PVC Fill Film (PVC heat exchange layer)
The innovative PVC filler heat exchange layer features a comprehensive design integrating filler, air inlet grille, and drift eliminator to ensure uniform air intake, drastically reduce water drift losses, and maximize heat transfer efficiency. The unique texture maximizes the heat exchange surface area, boosting overall performance. Adaptable to high-temperature materials for specialized project needs.
5. MBD PVC Drift Eliminator
Specially crafted for closed cooling towers, this drift eliminator excels in efficiently capturing airborne water droplets, presenting minimal wind resistance, and achieving a remarkable capture rate of 99.99%, thereby ensuring peak heat transfer efficiency.
6. Air Inlet Louver
Designed to ensure that cool, dry air is consistently drawn in and flows seamlessly through the coil and PVC heat exchange layer, this system limits sun exposure and curtails microbial growth, optimizing performance.
7. Heavy-duty construction
Built with a Z700 galvanized steel frame and shell of exceptional strength,it offers unparalleled corrosion resistance. For extreme environments, choose the optional SUS314/316 or NWN-Armour anti-corrosion coated steel for extraordinary protection.
8. Access Door
Provides entry to the tower's inner maintenance platform via the access door.
The strategic inclusion of an inspection platform inside the cooling tower significantly enhances the ease and convenience of performing routine inspections and maintenance tasks.
