Uses cooling tower special aluminum alloy axial flow fan,forward type blade structure design, small wind resistance, big air volume, low noise, good performance, high efficiency. Streamline high strength fan stack gurantees airflow uniform through the fan inlet and outlet area, maximum reduce the energy comsuption. Fan motor's protection class: IP55, Insulation class: F class.
Cooling coils as the core parts of closed cooling tower, are maded 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 galvanised) to enhance the coil pipe anti-corrosion ability, extend service life.
Copper coils (T type) are used by T2 deoxidized 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.
Shell plate uses imported aluminium zinc plate, which is one of the strongest corrision resistance plate, service life is 3-6 times of ordinary galvanized sheet, with strong termal resistance, high heat resistance, beautiful appearance, ect.
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.
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, redeased 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.
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 icefree even in extremely cold weather.
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 exchage 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.

| Instructions for Selection 1. Confirm condensing temperature, wet bulb temperature. 2. Calculate total heat abstraction amount that goes through system to condensers. 3. Take a reference to below Graph 1 or Graph 2, select heat abstraction amount correction index. 4. Total amount of heat abstraction multiplies heat correction index equals to the condensing load during the working conditions. 5. Take a reference to Graph Specification sheet, select the heat abstraction amount data which is bigger or equivalent to the data after correction. |
