Closed Circuit Cooler

A closed circuit cooling tower or dry cooling tower involves no contact between the air and the fluid being cooled.

Closed circuit cooler.

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. The coil serves to isolate the process fluid from the outside air keeping it clean and contaminate free in a. Bringing evapco s advanced technology design to closed circuit coolers the atwb features the thermal pak ii coil with crosscool internal tube enhancement offering incredible evaporative cooling. Closed circuit cooling towers keep the process fluid clean and contaminant free in a closed loop.

The original advanced technology closed circuit cooler provides an induced draft axial fan solution for a wide array of cooling applications. Our finned systems enhance heat exchange to the tube system and allow low material usage without performance loss. Bringing evapco s advanced technology design to closed circuit coolers the catwb features the. Thermaltake s offering is slightly pricier than other options but you.

1 an external circuit in which spray water circulates over the coil and mixes with the outside air and 2 an internal circuit in which the process fluid to be cooled circulates inside the coil. Tooling flexibility allows each system to be adjusted with its tube banks side by side or. Closed circuit coolers are designed according to customers requirements and assure exact compliance with their performance specifications. Evaporative closed circuit coolers eliminate the need for a heat exchanger between the process loop and the heat rejection equipment.

Thermaltake s water 3 0 is the cadillac of closed loop cooling if your cadillac has led ground effects and flashy rims. For closed circuit cooling delta recommends a cooling tower plus a plate heat exchanger system. 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. Unlike in a car where the antifreeze water circulates through an air cooled radiator a closed cooling system uses lake or ocean water flowing through a heat exchanger to remove heat from the engines.

Closed loop cooling requires more energy and has higher initial and life cycle costs than an open cooling tower but provides an added protection to expensive processes or chillers being cooled. This creates two separate fluid circuits.
