Introducing the Mixed Flow Evaporative Fluid Coolers/Closed Cooling Tower, engineered for outstanding performance and reliability.
NWF Series The NWF series closed cooling tower showcases advanced composite flow cooling technology, ensuring stable and efficient operation that's both energy-saving and environmentally conscious. As the spray water cools the heat exchange coil, it smoothly transitions into the cold water basin via the innovative PVC heat exchange layer. This process significantly reduces tower temperature while also minimizing noise typically generated by water impacting the bottom basin directly.
Revolutionary High-Efficiency Mixed Flow Closed Circuit System
Operation Excellence
Our system utilizes an advanced serpentine coil heat exchanger for fluid medium cooling, supported by a continuous external spray that expertly moistens the coil surface. This strategic setup facilitates efficient cooling, allowing seamless heat exchange between the cooled medium and spray water via a partition wall heat exchanger, creating a fully enclosed cooling loop. Low-temperature, dry air enters laterally, intersecting with the spray water flow to form a powerful composite heat transfer driven by fans. After comprehensive heat exchange, high-temperature saturated air is efficiently expelled from the tower, while the spray water undergoes an additional heat transfer in the PVC exchange layer before collecting in the water basin, optimizing heat removal for unparalleled cooling efficiency.
Unmatched Advantages
> The Sophisticated Mixed Flow Close-Loop Circulation System ensures media purity, significantly lowers maintenance costs, and expertly conserves valuable water resources. all while delivering exceptional cooling.
