Introducing the Newin NWN Counter Flow Closed Type Cooling Tower
NWN SeriesDiscover the innovative NWN series counter flow closed type cooling towers, designed with a closed loop system to support efficient dry operation mode without the need for spray water during winter months. These towers are capable of replacing traditional chillers, resulting in significantly reduced energy consumption and operational costs during the colder season.
Working Mechanism: Experience the advanced cooling process as the fluid medium, awaiting cooling, circulates through the high-efficiency serpentine heat exchanger. The external spray system ensures the coil surface remains continuously wet, optimizing the cooling effect. This ingenious system allows the cooled medium to traverse the partition heat exchanger, seamlessly interacting with the spray water for superior heat exchange efficiency.
Features
- Embrace the power of pure coil cooling! Our system excels by accommodating high temperature water, ensuring efficient and rapid heat exchange like never before.
- Experience the advantages of a Closed Loop System: pristine and clean medium, minimized scaling risk, and stellar energy and water conservation.
- Designed for modern efficiency, our compact structure offers optimal space-saving solutions, facilitating effortless shipping and installation.
COOLING TOWER COMPONENTS
1. Axial Flow Fan
Engineered with a special aluminum alloy, our axial flow fan boasts a forward-type blade design minimizing wind resistance while maximizing airflow. This high-efficiency, low-noise solution ensures smooth operation. The streamline high-strength fan stack maintains even airflow, reducing energy demands. Motor flexibility: IP55 protection, F class insulation, with two-speed, VFD, or anti-explosion motors available.
2. EVD PVC Drift Eliminator
Our premium drift eliminator effectively captures airborne water droplets with minimal wind resistance, achieving a remarkable capture rate of 99.99% for peak heat transfer performance.
3. Uniform Water Distribution
Revolutionize your cooling process with our strategically positioned Three-splashed-Nozzles. They ensure even water distribution under low pressure, with a large caliber and three splashed type design, ensuring blockage resistance and enhanced spray coverage for continuous and effective cooling.
4. Stainless Steel Heat Exchange Coil
Built to perform, our stainless steel heat exchange coil utilizes a serpentine bending tube and robust framework for superior thermal efficiency. It ensures full contact with spray water for outstanding heat exchange while being resistant to corrosion, lightweight, and recyclable.
5. EVL Inlet Grille
Featuring a special 3D stereo 45-degree ventilation channel, our inlet grille significantly boosts product rigidity and wind load resistance.
It also reduces noise and inhibits algae growth.
Enduring anti-corrosion, UV resistance, and maintenance-free performance.
6. Heavy-duty Construction
Crafted from high-quality Z700 galvanized steel, our frame and shell are designed for exceptional corrosion resistance. For extreme environments, choose optional SUS314/316 or NWN-Armour coated steel for unmatched protection.
