NWFL series dry air cooler is  a type of cooling tower specially designed to the industiry that wet cooling equipement is not ideal working condition. Such as air conditioning system glycol water solution, hospital equipement, computer room installations, etc.

Advantages

> No evaporation design, saving water consumption.

> Closed circuit, glycol water could avoid the frozen problem in cold season.

> High efficient EC fan drive system.

> Keeps environment dry and clean without water open to air.

> Factory assembled, easy installation and maintenance.

Components & Options

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.

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.
