Mixed Flow Evaporative Fluid Coolers/Closed Cooling Tower
NWF The NWF series closed cooling tower employs advanced composite flow cooling technology, offering unparalleled stability and energy efficiency, while being environmentally conscious. As the spray water descends, it cools the heat exchange coil and seamlessly flows into the cold water basin through a PVC heat exchange layer. This innovative design significantly lowers the internal tower temperature while skillfully minimizing noise, eliminating the typical sound associated with direct spray water impacts at the tower's base, ensuring a serene operation.
High-Efficiency Mixed Flow Closed Circuit System
Operation
Within this state-of-the-art cooling system, the fluid medium flows through a high-performance serpentine coil heat exchanger, where it meets an unyielding spray system that keeps the coil surface optimally moistened for maximum cooling effect. This process permits the cooled medium to efficiently exchange heat with the spray water across a partition wall heat exchanger, creating a closed loop for peak cooling performance. Fresh, low-temperature dry air enters the tower laterally, intersecting vertically with the spray water flow to forge a composite heat transfer dynamic. This synergy is driven by powerful fans, ensuring that after a thorough heat exchange, the high-temperature saturated air is rapidly expelled from the tower. Concurrently, the spray water undergoes a secondary heat transfer via a PVC heat exchange layer before gently cascading into a water collection basin, thereby achieving a superior heat removal process and unmatched cooling efficiency.
Advantage
> The Mixed flow close-loop circulation system ensures the purity of the media, significantly lowers maintenance costs, and wisely conserves invaluable water resources while providing efficient cooling.
> This innovative combination of a stainless steel coil heat exchanger and a PVC heat exchange layer delivers not only outstanding efficiency but also an aesthetic appeal. This cutting-edge design maximizes the heat transfer surface area, heightens heat exchange efficiency, and contributes to a significant reduction in noise.
> The innovative single-side air intake design remarkably reduces noise levels at the rear of the tower, making it ideal for environments where noise sensitivity is paramount.
> The product's remarkably compact structure and ingenious space-saving design, facilitate the seamless integration of multiple cooling towers.
