Mixed Flow Evaporative Fluid Coolers/Closed Cooling Tower
NWF Our NWF series closed cooling tower ingeniously integrates efficient composite flow cooling technology to ensure reliable, stable operation. This system is designed for energy savings and environmental sustainability. After the spray water cools the heat exchange coil, it seamlessly transitions into the cold water basin via the innovative PVC heat exchange layer. This process significantly reduces internal tower temperatures and minimizes noise associated with direct water impact.
High-Efficiency Mixed Flow Closed Circuit System
Operation
In our state-of-the-art cooling system, the fluid medium requiring temperature reduction travels through an ultra-efficient serpentine coil heat exchanger. An ongoing external spray system keeps the coil surface optimally moistened to facilitate maximum cooling. This allows the medium to exchange heat with the spray water through a sophisticated partition wall heat exchanger, forming a closed loop for superior cooling. Low-temperature, dry air cleverly enters from the side, intersecting vertically with the spray water flow, creating a dynamic composite heat transfer powered by robust fans. After comprehensive heat exchange, the high-temperature saturated air is expelled, and the spray water undergoes a secondary heat transfer using a cutting-edge PVC heat exchange layer before collecting in the basin, thus achieving remarkable cooling efficiency.
Advantage
> The Mixed flow close-loop circulation system ensures the media remains impeccably pure, significantly reducing maintenance costs while conserving precious water resources. while achieving efficient cooling.
> The combination of an advanced stainless steel coil heat exchanger and innovative PVC heat exchange layer demonstrates not only efficiency but also sophisticated elegance. This avant-garde design optimizes the heat transfer area, enhances heat exchange efficiency, and notably contributes to reduced noise levels.
> The strategic single-side air intake design curtails noise emissions at the rear, rendering it perfect for noise-sensitive settings.
> This product boasts a compact, space-efficient design, facilitating seamless integration for multiple cooling tower configurations.
