Introducing the revolutionary NEWIN NWF Series Mixed Flow Closed Type Cooling Tower, a marvel of modern engineering designed to optimize thermal performance and efficiency.
NWF The NWF series closed cooling tower pioneers in utilizing an advanced composite flow cooling technology, ensuring stable operation and superior energy efficiency. Engineered for eco-friendliness, once the innovative spray water method has cooled the heat exchange coil, this water is directed into the cold water basin via the specially designed PVC heat exchange layer. This process significantly reduces internal tower temperatures while effectively minimizing noise, eliminating the disturbance caused by spray water directly falling into the bottom basin.
Product Description
High-Efficiency Mixed Flow Closed Circuit System
Operation
Experience unparalleled cooling precision with our advanced serpentine coil heat exchanger, designed to handle the fluid medium requiring cooling with unmatched efficiency. The continuous external spray system keeps the coil surface perfectly moistened, facilitating optimal cooling as the medium exchanges heat with the spray water through a state-of-the-art partition wall heat exchanger. This creates a seamless closed loop for superior cooling effectiveness. As low-temperature dry air enters the tower laterally, it merges in a vertical cross-flow with the direction of the spray water flow, forming a unique composite heat transfer mechanism augmented by powerful fans. The result? High-temperature saturated air is expelled from the tower, while the spray water, having undergone a secondary heat transfer via a specialized PVC heat exchange layer, cascades into a water collection basin, ensuring maximum heat removal for top-tier cooling efficiency.
Advantage
> The Mixed flow close-loop circulation system ensures the purity of the media, significantly cuts down on maintenance costs, and efficiently conserves valuable water resources while maintaining exceptional cooling performance.
> The seamless integration of a stainless steel coil heat exchanger with a PVC heat exchange layer is not just functional but also aesthetically pleasing. This groundbreaking design optimizes the heat transfer area, bolsters heat exchange efficiency, and even aids in noise reduction.
> The innovative single-side air intake design effectively minimizes noise emissions, thereby making it the perfect choice for noise-sensitive environments.
> The product boasts a compact structure and a space-saving design, enabling the seamless integration of multiple cooling towers.
Features
COOLING TOWER PARTS
1. Axial Flow Fan
Crafted with precision, the aluminum alloy axial flow fan stands out for its low operational noise, unparalleled stability, and commendable efficiency. It boasts a motor with a robust protection grade of IP55 and an insulation grade of F, ensuring the highest levels of safety and reliability.
2. External Spray System
This advanced spray system is designed to delicately sprinkle cool water over the heat exchange coil, perpetually wetting its surface to maximize cooling efficiency.
3. Stainless Steel Heat Exchange Coil
Our stainless steel coils are engineered to deliver exceptional heat exchange efficiency, offering remarkable corrosion resistance. They are lightweight, extend the equipment's lifespan, and are environmentally friendly due to their recyclable nature.
4. MAH PVC Fill Film (PVC heat exchange layer)
The innovative PVC filler heat exchange layer integrates a filler, air inlet grille, and drift eliminator, ensuring consistent air intake, substantially reducing water drift loss, and optimizing heat transfer performance. Its distinctive surface texture offers a generous heat exchange area, boosting overall efficiency. For specific project needs, this filler can be upgraded to withstand high temperatures.
5. MBD PVC Drift Eliminator
Specially crafted for closed cooling towers, this drift eliminator excels at efficiently capturing airborne water droplets with minimal wind resistance, achieving an extraordinary capture rate of 99.99%, thereby securing exceptional heat transfer performance.
6. Air Inlet Louver
Designed to ensure even suction of cool, dry air through the coil and PVC heat exchange layer, it also minimizes sun exposure and inhibits microbial growth.
7. Heavy-duty Construction
Our robust Z700 galvanized steel frame and shell stand as a testament to supreme corrosion resistance.For particularly demanding environments, optional SUS314/316 or NWN-Armour anti-corrosion coated steel provides unmatched protection.
8. Access Door
A convenient access door leads to the tower's inner maintenance platform.
The presence of an inspection platform inside the cooling tower significantly enhances ease of inspections and maintenance operations.
