Cooling Tower Solutions

Cooling water tower principle and application:
Module of closed cooling tower is red copper coil with high heat transfer efficiency, allows working fluid (purified water or other liquid) pipeline pass through, makes heat exchange with air through fan to complete at a time so as to achieve energy efficiency and environmental protection and maintain pipeline cooled clean and smooth. It is available for long-term operation by connecting water inlet and outlet at user's site. It is another high-end choice for modern industrial cooling and is widely applicable to complete induction and heating equipment, IF furnace, die casting machine, etc.

Applicable scope

★Induction heating industry

★Industrial fluid

★Air conditioning system

★Water jacket cooling of air  compressor

★Injection molding machine  cooling 

★Transformer cooling 

★Glass melting furnace cooling  

★Power plant 

★Chemical plant

Working principle of closed cooling tower

The cold fluid flows through the coiled pipe in the closed cooling tower to conduct heat to the wall of coiled pipe; the fan at top of the  tower conducts air-pumping operation. The outer-circulation spray water and refresh air taken in by the fan fully come into contact in  the tower to exchange latent heat and sensible heat, and make the spray water temperature reduced. The spray water of lower  temperature can form water film in coil pipe wall to absorb the heat of the coil pipe wall and thus take away the heat carrying of the  medium to achieve the purpose of cooling. The pre-cooling filling in the tower helps to further cool the outer circulation. In the process of heat exchange, the heat carrying medium in the coiled pipe will maintain its original quality characteristics because  it does not directly contact with the air and will not be polluted, concentrated, diluted and volatilized. In addition to a small amount of  evaporation loss, the spray water outside the coiled pipe comes together at the bottom of the tower and circulates for use.  In the process of heat exchange, the heat carrying medium in the coiled pipe will maintain its original quality characteristics because  it does not directly contact with the air and will not be polluted, concentrated, diluted and volatilized.
