HydroThrift - Open Evaporative (OE) Cooling System - Brochure

Open Evaporative Cooling Systems.In applications where an evaporative-type, closed loop (CE) glycol system cannot be used due to budget constraints or application considerations, an Open Evaporative (OE) cooling system will be offered. OE-type systems are more economical in terms of initial equipment costs; however, they may incur maintenance costs associated with scaling, fouling, and water treatment packages. OE-type systems are also operated where heat transfer fluids, such as glycols, are not allowed, and/or the cooling medium comes in direct contact with customer product, such as plastic and aluminum extrusions.
