Product Description

Introducing the Newin NWN Counter Flow Closed Type Cooling Tower-an epitome of innovation and efficiency in the world of temperature regulation systems.
Closed Circuit Coolers for Optimal Inlet/Outlet Temperature Control

Unveil the potential of NWN technology.
Experience the pinnacle of cooling performance with our series of counter flow closed type cooling towers. Designed for a closed loop system, these towers support a dry operation mode without spray water during the winter months, making it a cost-effective alternative to chillers. By leveraging this advanced system, users can achieve extraordinary reductions in energy consumption, optimizing efficiency like never before.

Working Principle: The system efficiently channels the fluid medium in need of cooling through a state-of-the-art serpentine heat exchanger. The external spray system ensures the coil's surface remains continuously wet for optimal cooling. This design allows the cooled medium to seamlessly transition through the partition heat exchanger, where spray water facilitates exceptional heat exchange. This innovative process guarantees superior cooling results and energy savings.
