Introducing our Mixed Flow Evaporative Fluid Coolers/Closed Cooling Tower, a marvel of modern engineering offering unmatched thermal performance.
NWF The NWF series closed cooling tower harnesses groundbreaking composite flow cooling technology. It operates with remarkable stability, offering significant energy savings while prioritizing environmental sustainability. Once the spray water completes its cooling mission, it is smartly directed into the cold water basin via the PVC heat exchange layer, ensuring further temperature reduction inside the tower. This innovative process also minimizes the noise typically produced by the direct impact of spray water into the bottom basin.
Our High-Efficiency Mixed Flow Closed Circuit System is masterfully designed to deliver superior thermal performance and energy conservation.
Operation
Cooling commences as the fluid medium navigates through the high-efficiency serpentine coil heat exchanger. A continuous external spray system bathes the coil surface, facilitating efficient cooling. This cooled medium exchanges heat with the spray water through a partition wall heat exchanger, maintaining a closed loop for optimal cooling. Fresh, low-temperature dry air enters laterally, intersecting vertically with the spray water flow, creating a dynamic composite heat transfer system powered by robust fans. The system expels high-temperature saturated air while the spray water undergoes a secondary heat transfer through a sophisticated PVC heat exchange layer before gracefully descending into the water collection basin, ensuring the utmost cooling efficacy.
