Introducing the Newin NWN Counter Flow Closed Type Cooling Tower - a pinnacle of cooling technology and efficiency.
NWNThe NWN series counter flow closed type cooling tower is a marvel of engineering, designed with a closed loop system that supports dry operation mode without the need for spray water during winter. This innovative feature allows it to seamlessly replace chillers in colder months, resulting in a significant reduction in energy consumption, making it an eco-friendly and cost-effective solution for HVAC applications.
Operational Excellence: The high-efficiency serpentine heat exchanger ensures optimal cooling by circulating the fluid medium that requires cooling. The advanced external spray system works tirelessly to wet the surface of the coil, maximizing cooling efficiency. This ensures that the cooled medium effectively traverses the partition heat exchanger, engaging in a sophisticated heat exchange process with the spray water, thereby delivering unparalleled cooling performance.
Features
- Experience unmatched heat exchange efficiency with our pure coil cooling system that effortlessly accommodates high-temperature water for maximum performance.
- Embrace a pristine closed loop system with a clean medium that resists scale formation, ensuring exceptional energy and water conservation.
- Designed for optimal space usage, the compact structure facilitates economic space occupation, simplifying both shipping and installation processes.
PREMIUM COOLING TOWER COMPONENTS
1. Axial Flow Fan
Crafted from advanced cooling tower aluminum alloy, our axial flow fan features forward-type blades that minimize wind resistance while maximizing air volume and performance efficiency. The fan stack's aerodynamic design promotes uniform airflow, significantly reducing energy use. Built for endurance, the fan motor offers IP55 protection and F class insulation, with options including two-speed, VFD, or anti-explosion motors.
2. EVD PVC Drift Eliminator
Achieve optimal heat transfer with an impressive 99.99% capture rate of airborne water droplets, ensuring minimal wind resistance and superior performance.
3. Uniform Water Distribution
Engineered with precision, our Three-splashed-Nozzles offer uniform water distribution at low pressure. The large caliber and triple-splash design prevent blockages, expand spray coverage, and guarantee continuous cooling efficiency.
4. Stainless Steel Heat Exchange Coil
Our top-tier stainless steel coil, crafted with serpentine bending technology, delivers outstanding heat exchange and cooling efficiency. These lightweight, corrosion-resistant pipes ensure full contact with spray water, enhancing thermal performance while remaining environmentally friendly.
5. EVL Inlet Grille
Featuring a specialized 3D stereo 45-degree ventilation channel, our grille significantly bolsters product rigidity and wind load resistance.
Effectively reduces noise and impedes algae growth.
Boasts anti-corrosion, anti-ultraviolet properties, offering a maintenance-free solution.
6. Robust Construction
Employing high-quality Z700 galvanized steel, our construction ensures lasting corrosion resistance. For extreme conditions, choose our SUS314/316 or NWN-Armour coated steel for unparalleled protection.
