タイトルまたは説明

Air cooling: working fluid(soft water or other fluid)circulates in the coil pipe of the closed cooling tower, after the fluid heat is absorbed by the coil pipe wall, the heat is then exhausted by the draught fan on the top.
 Water cooling: When the fluid temperature is too high(surpassing setting temperature), the spray pump automatically spray the water on the pipe wall and form water film. Then the water film evaporats to absorb heat(latent heat of vaporization).Part of spray water becomes steam and is taken away by flowing air, the rest part becomes water drops and fall on the catch basin for next circulation The fluid inside the coil pipe is in closed loop and wont lose theoretically. The consumption of spray water is only 0.**0.2% of unit flow.
Keep process fluid free from contamination
The  less likely  possibility of scaling
 
Reduce system energy consumption cost
 
Reduce system maintenance costs
 
Ensure reliable and efficient operation of equipment throughout the year.
