Water saving and hybrid products from Baltimore Aircoil Company are usually of the closed circuit type. The hybrid wet-dry products cool the liquid to be cooled by efficiently combining dry sensible air cooling with evaporative cooling. These products include two or more distinctive heat transfer surfaces or sections combined into one product optimizing the use of ambient dry and wet bulb temperature. Low water and water treatment cost, vastly improved operational safety and virtual elimination of visible plume are the main advantages of “intelligent”
water saving products.
