Counter Flow Closed Cooling Tower

Process principle

The heated working fluid inlet from cooling coils, then the waste heat be took away by the fall down spray water and reverse flow with the cold dry air which is inlet from the bottom of the tower and form to saturated vapor in the process. The heat is exhausted out of tower by the top fan and the water is collected to bottom tank and circulate continuously by the special evaporator.

Characteristics

1.Compact Structure                                                                                                                   

Counter-flow closed tower has four faces for wind inlet，which is relatively uniform . The inner structure of the tower is more compact , reducing the footprint and meeting the needs of user space . Under the same occupation area , the heat transfer efficiency is higher than that of other models.    

2.High efficiency

There is a large height difference between the air inlet and outlet . and will not to short flow . which can ensure that the saturation humidity of the inlet air is relatively low . And the arrangement of the fan ensures the uniform distribution of air volume , less heat dissipation blind area and sufficient heat exchange.

3.Easy for installation

We can combine the tower with auxiliary together to be a whole suit , it will convenient for customers to operate , and easy to transportation & installation.

Product Structure & Details

Fan--Low noise large diameter fan

Low speed fully sealed motor adopts blades with super width. The fan is composed of aluminum blades and steel wheel hub, featuring low wind resistance, high rate of air flow, low noise, high efficiency and reliable performance and so on. The protective level is IP55, suitable used for out door.

( Blade options: aluminum alloy, aluminum alloy hollow, carbon fiber, polythylene )

Outer Sheel--Imported Aluminum-zinc Plate

The imported Aluminum-zinc plate is one of the best corrosion resistant materials at present, with life span 3-6 times than common galvanized steel. And has follwing advantages such like high strength and toughness, good heat resistance and beautiful appearance, etc.

( Shell material options: Aluminum-zinc plate, SuperDyma, 304 Stainless steel )

Cooling Coils--Different choices of material

Red Copper Coils: Good heat exchange effect, high antifreeze requirements. Pressure design 1.6Mpa.

Stanless Steel Coils: Pressure design 2.5Mpa, corrosion-resistance ability, cheaper.

Adopt advanced automatic welding equipment to ensure no leakage.

PLC--Brand:Siemens, Schneider

PLC intelligent control, local/remote control, can be adjusted according to different working conditions.

PVC Fills--High efficiency PVC material

High quality PVC material may effectively transfer heat and reducing the water flow to save energy resources.

( Air window options: steel louver type, pvc honeycomb type )

Spraying System--Efficient spray system

Spraying Nozzle: The high-efficiency water spary system provides important guarantee for the cooling capacity. Spray water is evenly distributed, and the spray nozzles are easy to clean and replace.

Spraying pump: Special circulating spary pump with the protective level is IP55, no leakage, long life span.

Auxiliary--Choose depend on your needs

Main circulationg pump

A pump with a backup, failure occurs the backup pump can automatically put into operation high efficiency. Low-vibration, low-noise and high energy efficient.

( Motor options: Simens, ABB, Datang, Dongyuan )
