The closed circuit cooling tower advantage
1.VS.Cooling Tower +Heat Exanger Combination
Closer approach to wet bulb temperature and reduce fouling improve process efficiency 
2.VS.Air-Cooled Systems
10-20°C lower process temperatures ,less required space ,and lower energy consumption .
3.VS.Once –Through Systems
Reduces environmental impact ,saving up to 95% of the cooling water .
4.Reduced installed Cost And Space Requirements
Effectively combines the function of a cooling tower and heat exchanger into one piece of equipment ,reduce required piping and system complexity .

Engineering considerations
1.Location 
Closed Circuit Cooling Towers must have an adequate supply of fresh air to all inlets.
When units are located adjacent to building walls or in enclosure .Care must be taken to ensure that the warm ,saturated discharge air is not deflected and drawn back to the air inlets .
2.Think on compatibility of liquid (gas)
The fluid to be cooled must be compatible with the coil material .Fluids not compatible with ciol materials can lead to corrosion and tube failure .Certain fluids may require occasional pressure cleaning or mechanical cleaning of the inside of coil tubes .in such cases the coil must be designed to provide this capability .
3.Piping and Valves 
Piping must be size and installed in accordance with good piping practice .All piping should be supported by pipe hangers or other supports ,not by the cooling tower .External shut off valves may also be required if the system design necessitates the isolation of individual tower cells .

4.Capacity Control
In general season ,the performance of most closed circuit cooling tower will vary dues to the change of its environmental wet bulb temperature .Therefore ,when the change of environmental temperature leads to the difference of liquid temperature ,in this case ,capacity control will be required .

How to prevent the cooling towers to be freezed

FAQ

(1)Your company is a manufacture or trading company?

We are a leading cooling tower manufacturer for 38 years . It is“famous brand”-Heng An manufacture in China 

(2) What is the difference between a "counter flow" and a "cross flow" cooling tower?

The crossflow or counterflow designation characterizes the orientation of the airflow within the heat-transfer media (fill) in the tower with respect to the direction of water flow.

In counterflow towers air travels vertically upwards through the fill and makes intimate contact with water droplets falling down through the fill media. Hence the air and water travel in opposite directions.

In crossflow cooling towers the air passes through the fill media in a horizontal direction, thus crossing the downward water flow. Counterflow towers are inherently more efficient than crossflow towers.
