Closed circuit cooling tower piping detail.

Jh closed circuit cooling tower closed loop cooling tower is equipped with a coil heat exchanger which separates cooling water into internal water and external water. 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. Cooling towers winter operation free cooling 371 16 kb. A closed circuit cooling tower or dry cooling tower involves no contact between the air and the fluid being cooled.

The essential element for a cooling tower to function is water and water needs to be delivered through a piping system. 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. Open tower system pump head requirements. Choosing closed circuit cooling towers over this open tower heat exchanger combination may still be a better choice for the following reasons.

Closed circuit cooling towers whaley products cls series closed circuit cooling tower systems can serve any industry that needs their water circuits clean at all times. Static height not considered for pump selection in closed loop. Internal water supplies cooling water for machinery use and it is a closed loop that can easy to maintain the cooling water quality. Flow friction loss h closed loop piping circuit.

Utilizing wpi s proven wp series cooling towers in a closed loop circuit with stainless steel heat exchangers flushable stainless steel strainers and a recirculation. The pumping head determination procedure for the open tower piping loop differs from the conventional closed. 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. It seems simple but how effectively a cooling tower piping system is designed and installed can have a critical impact on system efficiency functionality and even safety.

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.
