  • What is a Closed Circuit Cooling Tower | Baltimore Aircoil

    Closed circuit cooling towers, also known as evaporative fluid coolers, keep the system clean and contaminantfree 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, and (2) an internal circuit, in which the process fluid to be cooled circulates inside the coil.
