Let jh cooling tower expert tell you the reason.
Open circuit vs closed circuit cooling tower.
An immediate open circuit cooling tower is an encased structure that conveys warm water over a maze like pressing or fill which gives an extended air water interface for warming of the air and dissipation to happen.
The water is cooled as it falls through the fill and is then.
I am new to the industry so i have very limited knowledge of the subject.
A closed circuit cooling tower or dry cooling tower involves no contact between the air and the fluid being cooled.
I have been recently asked to have a have an old bac cooling tower replaced with little to no down time to the factory.
Addition of a heat exchanger pump piping etc to the open tower loop brings the initial cost much closer to that of the closed circuit tower system.
Closed circuit cooling tower s price is higher than open cooling tower but we still say closed circuit cooling tower s price is lower than open cooling tower.
In a closed circuit cooler process fluid is circulated through coils within the unit.
Water fee costs a lot by spray and evaporation.
Bac leads the industry in the design and manufacturing of closed circuit cooling towers with the most efficient and cost effective units with both water and.
Closed circuit cooling tower is used in the following applications.
This tower has two separate fluid circuits one in which the fluid is recirculated on the outside of the second circuit which is a bundle of tubes through which the hot water is flowing.
Water source heat pumps industrial processes air compressors weld machine cooling mould water cooling power plant auxiliary cooling furnace cooling transformer cooling closed condenser loops critical systems and systems requiring plume elimination.
Cooling towers with piping and plate heat exchanger also exist.
A cooling tower is a heat exchanger that uses the direct contact with the air to cool down water.
There is no direct contact between the water to cool down and the air inside closed circuit cooling towers but an additional heat exchanger is however used.

Closed circuit cooling towers.
Addition of a heat exchanger pump piping etc to the open tower loop brings the initial cost much closer to that of the closed circuit tower system.
Unlike a cooling tower where process water is used as the energy transfer medium and is open to the atmosphere the coil inside a closed circuit cooler isolates the process fluid.
Choosing closed circuit cooling towers over this open tower heat exchanger combination may still be a better choice for the following reasons.
