NEWIN Closed circuit cooling tower (also called evaporative fluid cooler or closed cooling tower) is a type of cooling tower that equipped with a coil heat ex-changer inside cooling tower, and cooling tower the water by exchanging the heat trough the fresh air, spray water and circulation water. Because it is a closed cycle, water quality guaranteed not affected by pollution, greatly protected the efficient operation of the main equipment, improved the service life. When air temperature is low. Spay pump can stop working to save water. With the implementation of the national policy for energy conservation and emissions reduction and the growing scarcity of water resources, in recent years closed circuit cooling tower are widely used in the iron and steel metallurgy, power electronics, mechanical processing, air conditioning system and other industries.

Components and Parts
Axial Flow Fan
Uses cooling tower special aluminum alloy axial flow fan,forward type bladestructure design, small wind resistance, big air volume, low noise, good performance, high efficiency. Streamline high strength fan stack grantees airflow uniform through the fan inlet and outlet area, maximum reduce the energy consumption. Fan motor's protection class: IP55, Insulation class: F class.
Cooling coil
Cooling coils as the core parts of closed cooling tower, are made up of great quality copper coil or steel coil. Coil inside is through cooling medium, outside is cooled by water spray to meet the cooling requirement. Steel coils (G type) are used by high quality Ф25 mm seamless fluid tube, and processed by H.D.G.(hot dip galvanized) to enhance the coil pipe anti-corrosion ability, extend service life. Copper coils (T type) are used by T2 oxidized acid copper tube, silver electrode is used to connect between the copper pipe and elbow welding, low solder joint and good quality, design pressure is 1.2MPa.
Aluminium Zinc Plate
Shell plate uses imported aluminium zinc plate, which is one of the strongest corrosion resistance plate, service life is 3-6 times of ordinary galvanized sheet, with strong thermal resistance, high heat resistance, beautiful appearance, ect.
Spray Pump
Used great mechanical seal to prevent from the leakage, made by dedicated outdoor motor, and special configuration imported bearings, to ensure that the fan, water pump has long term reliable operation, low power, large flow, low noise, excellent performance, etc. The pump body is precision casting, strong and long service life.
Drift Eliminator
Original detachable eliminator adopts good performance PVC material, its special structure could change the air flow direction, effectively remove from the wet air moisture in the air, reduce the drift loss below 0.001%, maximum save the water, what's more, to make sure the area around cooling tower no pollution, and prevent from the germs spreading.
High Efficiency Infill
This infill is a hanging film type fill which spreads the water into a thin film, flowing over large vertical surfaces, promoting maximum exposure to air flow. It incorporates highly efficient cellular eliminators and louvers, integrally molded within the fill sheets, preventing water from escaping and assuring precise air distribution throughout wide variations in airflow. Unlike towers equipped with separate external louvers, this fill operates virtually ice-free even in extremely cold weather.
Advanced Water Distribution System
The spray system uses in a variety of high flow rate and anti clogging basket type nozzles, to ensure the continuous uniform water spraying on the surface of the coil. Under the help of induced air, water can cover all the coils to the utmost extent to do the complete heat exchange among water, air and refrigerant. In this case, heat transfer efficiency will increase dramatically. The nozzle is connected on spray pipe branch. When cleaning, the nozzles and spray pipe branch can be easily dismounted.
