Product Description

Introducing the remarkable Newin NWN Counter Flow Closed Type Cooling Tower, a marvel of modern engineering designed to meet and exceed your cooling needs.

NWNThis cutting-edge series of counter flow closed type cooling towers operates in a closed loop, offering superior efficiency and versatility. It supports dry operation mode without the need for spray water during winter, effectively replacing traditional chillers and significantly slashing energy consumption.

Operational Excellence: Experience unparalleled cooling performance as the fluid medium flows through a high-efficiency serpentine heat exchanger. This process is enhanced by an external spray system that continuously wets the coil surface for optimized cooling. The cooled medium then seamlessly transitions through the partition heat exchanger, delivering exceptional heat exchange results through water spraying.

Features

- Experience the pinnacle of thermal transfer with our pure coil cooling, expertly engineered to accommodate high-temperature water for unmatched heat exchange efficiency.
- Our closed-loop system ensures a pristine medium, minimizing scaling for optimal cleanliness; it stands as a beacon of energy efficiency and water conservation.
- Designed to perfection, our cooling tower boasts a compact yet robust structure, economizing space while simplifying shipping and installation processes with grace.
