Intercooler: Coolant is supplied to a tube-and-fin bundle, located in a vessel where air flows through and cools the coolant. . Air cooled unit draws cooling air from different ends of the unit to cool the system, dependent upon the units cooling system design. Check with the generator's manufacturer to determine the optimal cooling method for the system. Open Ventilated Air Cooled: In the open-vent system, atmospheric air is drawn directly through filters passes through the generator and the. . Air cooled generators are produced in two basic configurations: Open ventilated (OV) - In the OV design, outside air is drawn directly from outside the unit through filters, passes through the generator and is discharged outside the generator. Totally enclosed water to air cooled (TEWAC) - In the. . from a few kWs to several MWs, in open and enclosed configurations.
