Product Description

Introducing the Newin NWN Counter Flow Closed Type Cooling Tower-a pinnacle of innovation in cooling technology.

NWNThe NWN series offers a revolutionary counter flow closed type cooling tower, engineered with a closed loop system. This advanced design supports dry operation mode without the need for spray water during winter months, effectively replacing traditional chillers. As a result, it significantly reduces energy consumption and operational costs.

Operational Excellence: Experience superior cooling efficiency as the fluid medium circulates within the high-performance serpentine heat exchanger. The external spray system persistently moistens the coil surface, enhancing cooling effectiveness. This process ensures the medium is optimally cooled as it navigates through the partition heat exchanger, coupled with strategic spray water heat exchange.

Features

- Experience the brilliance of pure coil cooling, capable of handling high-temperature water effortlessly, enabling an efficient and effective heat exchange process.
- Embrace the innovation of a closed-loop system-it's not just about clean medium; it's about an energy-efficient, water-conserving marvel that resists scaling.
- Enjoy the benefits of a compact, economically-space-optimizing structure that ensures ease of shipping and a breeze of installation.

COOLING TOWER PARTS

1. Axial Flow Fan
Harness the power of a cooling tower's specialized aluminum alloy axial flow fan. Its forward-type blade structure design minimizes wind resistance while maximizing air volume, performance, and efficiency with low noise. The streamlined, high-strength fan stack ensures uniform airflow through the fan inlet and outlet area, significantly reducing energy consumption. The fan motor is well-protected with an IP55 protection class and an F-class insulation. Choose from options like a two-speed, VFD, or anti-explosion motor for customized performance.

2. EVD PVC Drift Eliminator
Masterfully engineered, the EVD PVC Drift Eliminator efficiently extracts airborne water droplets with minimal wind resistance and boasts an impressive 99.99% capture rate, ensuring optimal heat transfer performance at all times.

3. Uniform Water Distribution
Discover the precision of strategically positioned Three-splashed-Nozzles, delivering even water distribution under low-pressure flow. The large caliber and three-splash design minimize blockages while enhancing spray coverage, guaranteeing continuous effective spraying and ensuring the cooling tower's efficient performance.

4. Stainless Steel Heat Exchange Coil
Our high-quality heat exchange coil boasts a stainless steel serpentine bending tube supported by a robust framework. This ensures superior thermal performance through full contact with spray water, fostering efficient heat exchange and effective cooling. The stainless steel pipes are resistant to corrosion, lightweight, and recyclable, offering a lasting environmental solution.

5. EVL Inlet Grille
The special 3D stereo 45-degree ventilation channel significantly enhances product rigidity and wind load resistance, offering unparalleled strength.
Engineered to reduce noise while preventing algae growth, transforming your cooling tower experience.
Designed to be anti-corrosion, anti-ultraviolet, and maintenance-free, for a worry-free operation.

6. Heavy-duty Construction
Built with high-quality Z700 galvanized steel frame and shell, offering robust corrosion resistance. In particularly harsh environments, choose the optional SUS314/316 or NWN-Armour anti-corrosion coated steel for exceptional protection.

Options
· Vibration Cut-off Switch
