Introducing the Newin Nwn Counter Flow Closed Type Cooling Tower, a groundbreaking solution designed by Newin (Guangdong) Machinery Co., Ltd. for optimal and efficient water management.
NWNOur NWN series counter flow closed type cooling tower is a marvel of engineering, offering a closed loop system that supports an energy-efficient, dry operation mode without the need for spray water during the winter months. It is a sustainable alternative to traditional chillers, significantly reducing energy consumption while maintaining high performance.
Functionality: This advanced system operates by channeling the fluid medium requiring cooling through a state-of-the-art, high-efficiency serpentine heat exchanger. The innovative external spray system ensures the coil's surface remains continuously wet for optimal cooling performance. As the cooled medium traverses the partition heat exchanger, it seamlessly engages in heat exchange with the surrounding spray water, ensuring maximum efficiency and effectiveness.
