Closed Circuit Cooling Tower

Descripción del producto

Closed circuit cooling towers operate in a manner similar to open cooling towers, except that the heat load to be rejected is transferred from the process fluid (the fluid being cooled) to the ambient air through a heat exchange coil. The coil serves to isolate the process fluid from the outside air, keeping it clean and contaminate free in a closed loop. This creates two separate fluid circuits:

(1) An external circuit, in which spray water circulates over the coil and mixes with the outside air

(2) An internal circuit, in which the process fluid circulates inside the coil.

During operation, heat is transferred from the internal circuit, through the coil to the spray water, and then to the atmosphere as a portion of the water evaporates.

Open cooling water system is subject to water pollution and, as a result, the bacteria of miscellaneous sorts proliferate fast to become a grave threat to human health by dissipating the bacteria containing vapor. A popular disease from open water cooling system is legionnaire that endangers human life by causing pneumonia, which is especially true for people living & working in the buildings with central air conditioners. Closed circuit cooling tower has the largest proportion of cooling water circulating inside enclosed loop, thus is not subject to water pollution. The specially designed louvers not only reduce the limited spray water drift to minimum level, but also effectively stop outside sunlight and particles from entering the tower basin cultivating the growth of bacteria.

CCCT system adopts **0% closed circuit circulation for process fluid that saves water from loss in any form.  Special baffle is used to reduce unavoidable spray water loss to the lowest point without negative impact on the cooling efficiency. The prominent water saving nature is one of the most important factors deciding the popular use of closed circuit cooling tower.

Closed circuit cooling tower is designed to operate within very limited space, accounting for 1/**1/5 that of open cooling system, saving any form of ground construction. The effective drift eliminator baffle enables closed circuit cooling towers to be used indoors close to production line without wetting the groud.

Closed circuit cooling tower has self-attached water basin and fully enclosed cooling coils for preservation of cooling water that saves any form of ground construction cost. Under open cooling tower system, the large water pool is a necessity to supply all process cooling water, and the related investment will be of no use if the open cooling tower is to be re-installed to a different site.

The installation of closed circuit cooling tower includes merely the connection of piping and electrical system that can be done even by technical workers without training.

Due to the scaling-free nature of closed circuit cooling tower, a great deal of human efforts for monthly or quarterly maintenance can be saved, which are normally neglected due to the busy production schedule and tend to cause sudden stop with long accumulation of scaling.

Choosing closed circuit cooling tower comes to be part of our responsibility for protection of life and environment with safe & saving industrial cooling solutions.
