Closed loop cooling water machine (also known as closed cooling tower, or closed cooling tower) is a tube heat exchanger placed in the tower to ensure the cooling effect through the heat exchange of circulating air, spray water outside the pipe, and circulating water inside the pipe.

The whole series of industrial chiller uses the principle of cold and heat exchange for cooling, which can be quickly cooled, temperature control is stable, and is not affected by environmental factors.

It is tube heat exchange placed in the tower to ensure the cooling effect through the heat exchange of circulating air,spray water outside the pipe, and circulating water inside the pipe.
