Working Principle

Newin Nwfl-Va Series Adiabatic Cooler High-Capacity Cooling for Refrigeration Solutions
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.

Components& Options
Newin Nwfl-Va Series Adiabatic Cooler High-Capacity Cooling for Refrigeration Solutions
· 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.
· Adiabatic Pre-cooler

- Evaporative cooling pads are made of cellular materials of impregnated cellulose with different flute and constructed in heavy gauge stainless steel framework. Water distribution from top of the pads for complete wetting.

-The external surface of the evaporative cooling pads is coated with an anti-UV treatment, providing increased durability and allowing for cleaning with a pressure washer, ultimately leading to an extended service life.

- 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.

 

· Options

- Increase the coil's resistance ability
- Coil freeze-up safeguard
- Low noise upgrade
- Increase the degree of redundancy If any customized requirements,  please contact NEWIN sales representative.
