NWFL-VA series is the V type dry air cooler designed with Adiabatic Cooling System.
Advantages
· V type design and adiabatic cooling system
High cooling efficiency with low water consumption.
· Optimal efficient components
Like EC motor Maximum system efficiency and energy saving.
· Large redundancy available.
Eliminating thermal performance loss.
· High reliability and Ease maintenance.
When NWFL-VA adiabatic cooler is in operation:
Cold water will flows from the top of the cooler and evenly through the evaporative cooling pads. The cool dry air will be drawn into by EC axial fan over the pads and precooled. This adiabatic precooling of the air has larger cooling capacity for cooling the warm process fluid.

Heavy-duty Construction
· The galvanized steel panel with NWN-Armour anti-corrosion coating have excellent resistance and corrosion resistance approaching the characteristics of stainless steel, allows the equipment to work with higher concentration cycles and thereby reduce water consumption.
· The coating can be easily repaired if damaged.
V Type Finned Coil Heat Exchanger
· The finned tube heat exchanger adopts a copper tube-aluminum fin composite design, maximizing heat transfer area for efficient thermal conduction.
· This structure rapidly transfers heat from the fluid to the air, maintaining excellent heat exchange performance under various complex working conditions.
· This design not only ensures stable operation of industrial equipment but also significantly reduces energy consumption, enhancing overall system efficiency.
EC Axial Fan
· The EC motor features direct-axis drive with IP55 protection and Class F insulation, ensuring reliable long-term operation in humid and hot environments with smooth performance. It achieves ultra-high energy efficiency up to IE5, delivering exceptional energy-saving performance.
· Equipped with maintenance-free bearings featuring a 60,000-hour service life and an insulated bearing system to prevent shaft current damage.
· Through static and dynamic testing during the production process, noise is minimized while meeting the heat exchange performance of the cooler; using PFC to keep harmonics below 35%, the EC fan system can maintain high static efficiency, even at low speeds.
Adiabatic Pre-cooler
· Adiabatic precooling is performed in evaporative cooling pads. This pads features specially treated multi-layer honeycomb fiber paper structure, offering excellent water absorption, permeability and uniform water distribution to maximize water-air contact area. A water distribution system forms a continuous water film on the surface, enabling efficient cooling through full air-water contact.
· Evaporative cooling pads with water circulation pump can help to achieve designed conditions in peak summer.
Adiabatic Intelligent controls
· EC fans Intelligent frequency conversion to meet different working conditions on site, save more energy.
· Force unit in dry operation in case water usage is prohibited.
