Product Description
Adiabatic Cooler NWFL-VA Series
NWFL-VA series is the V type dry air cooler designed with Adiabatic Cooling System. Efficient cooling throughout the year, free cooling solution suitable for data center and other facilities, and water consumption is greatly reduced compared with evaporative cooling.· 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 envenly 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.

1. Standard design working condition- Fluid in/out Temp. Difference: 5ºC.
2. Standard design ambient temperature- Temp. Approach: 17ºC.
3. Thermal design based on pure water.
4. Please contact NEWIN sales representative if the working condition is different from the above standard design condition.
· 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 coil heat exchanger made with copper tubes and aluminum fins adequately spaced to ensure the best performance in heat exchange. The copper tubes are fixed to the coil headers by brazing and to the finned coil by flaring, to ensure maximum continuity in thermal conduction.

· EC Axial Fan
- EC motor straight-shaft drive, motor protection grade is IP55, insulation grade is F, suitable for long-term operation in hot and humid environments, with smooth operation. The energy efficiency of EC motors can reach IE4 or above.
- The fan bearings adopt tapered roller bearings, which have large load-bearing capacity and long service life, with a rated service life of more than 20,000 hours.
- 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.
