Product Description

Introducing the NEWIN NWF Series: A Revolution in Mixed Flow Closed Type Cooling Towers

NWF The NWF series closed cooling tower by Newin (Guangdong) Machinery Co., Ltd. pioneers in employing cutting-edge composite flow cooling technology. This innovative design ensures stable operation while emphasizing energy efficiency and environmental sustainability. As the spray water adeptly cools the heat exchange coil, it seamlessly channels into the cold water basin via the PVC heat exchange layer. This strategic process significantly reduces temperature within the tower and minimizes the noise typically generated by spray water directly impacting the bottom basin. Experience a harmonious blend of performance and tranquility.

Product Description

 

High-Efficiency Mixed Flow Closed Circuit System

Operation
Witness a groundbreaking process where the fluid medium seeking cooling journeys through our highly efficient serpentine coil heat exchanger. Our system employs an uninterrupted external spray mechanism that diligently moistens the coil surface, enhancing the cooling process. This enables the cooled medium to seamlessly exchange heat with the spray water through a sophisticated partition wall heat exchanger, crafting a closed loop for optimal cooling. Ingeniously designed, low-temperature dry air enters the tower laterally, engaging in a vertical intersection with the spray water flow. This results in a composite heat transfer system, invigorated by powerful fans. Post heat exchange, high-temperature saturated air exits the tower, whilst the spray water undergoes an additional heat transfer phase via a PVC heat exchange layer, cascading into a water collection basin, thereby excelling in heat removal and ensuring unparalleled cooling efficiency.

Advantage
> The Mixed flow close-loop circulation system ensures the integrity of the media, significantly reduces maintenance costs, and astutely conserves essential water resources, while maintaining exceptional cooling performance.
> The combination of a stainless steel coil heat exchanger and PVC heat exchange layer is a triumph of efficiency and design. This innovative configuration not only maximizes the heat transfer area but also advances heat exchange efficiency, and notably contributes to noise reduction.
> The single-side air intake design reduces noise emissions at the rear of the tower, making it perfectly suited for environments where noise levels are a critical concern.
> The product boasts a compact structure with an intelligently space-saving design, permitting seamless integration of multiple cooling towers to meet diverse industrial needs.

Features

COOLING TOWER PARTS

1. Axial Flow Fan
Crafted with precision, the aluminum alloy axial flow fan emerges as a beacon of efficiency, seamlessly blending low noise, unwavering stability, and outstanding performance. Enhanced with a motor protection grade of IP55 and an insulation grade of F, this fan stands as a paragon of safety, promising both reliability and longevity.

2. External Spray System
Ingeniously engineered to spray cool water across the heat exchange coil, this system ensures an ever-moist surface, driving optimum cooling and performance.

3. Stainless Steel Heat Exchange Coil
Embodying excellence, the stainless steel coils deliver remarkable heat exchange efficiency while offering superior corrosion resistance. Lightweight and durable, they promise an extended equipment lifespan and are an environmentally sound choice due to their recyclability.

4. MAH PVC Fill Film (PVC heat exchange layer)
Innovatively designed, the PVC filler heat exchange layer incorporates an all-in-one design of filler, air inlet grille, and drift eliminator, ensuring consistent air intake and dramatically reducing water drift loss. This guarantees exceptional heat transfer. Its unique surface texture amplifies the heat exchange surface area, enhancing efficiency. For projects requiring specific conditions, the filler can be upgraded to high-temperature materials.

5. MBD PVC Drift Eliminator
Tailored specifically for closed cooling towers, this unique drift eliminator excels in capturing airborne water droplets with an unparalleled capture rate of 99.99%, while maintaining minimal wind resistance, ensuring superior heat transfer performance.

6. Air Inlet Louver
Designed to draw in cool, dry air smoothly, the air inlet louver ensures even distribution through the coil and the PVC heat exchange layer, curtailing both sun exposure and microbial growth effectively.

7. Heavy-duty construction
Engineered with a robust Z700 galvanized steel frame and shell,this construction offers exceptional corrosion resistance. For the most challenging environments, the option of SUS314/316 or NWN-Armour anti-corrosion coated steel provides unrivaled protection.

8. Access Door
Facilitating easy entry to the tower's inner maintenance platform, the inspection platform within the cooling tower is thoughtfully designed to enhance the ease and efficiency of conducting routine inspections and maintenance.
