Close Coupled Cooling is a last generation cooling system particularly used in data centers. The goal of close coupled cooling is to bring heat transfer closest to its source: the equipment rack. By moving the air conditioner closer to the equipment rack a more precise delivery of inlet air and a more immediate capture of […]

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

Here’s a more detailed breakdown: Two Fluid Circuits: The defining feature is the presence of two distinct fluid circuits. Primary Circuit: This is the closed loop where the fluid that needs cooling (e.g., process fluid in an industrial application or water in a chiller system) circulates within a coil. Secondary Circuit: Water from the...

A closed-circuit cooling tower is a heat rejection device that cools a circulating fluid (like water or a water-glycol mixture) by spraying it over a coil through which the fluid to be cooled is flowing. It’s characterized by having two separate fluid circuits: one for the fluid being cooled, which remains isolated within a coil, […]

Combined Flow Configuration Combined flow is the use of both a heat exchange coil and fill for heat transfer in a closed circuit cooling tower. The addition of fill to the traditional closed circuit cooling tower design reduces evaporation in the coil section, reducing the potential for scaling and fouling. BAC’s combined flow closed circuit...
