Abstract
A volatile solvent conservation modular unit and method for effecting solvent conservation is provided. The cooling coil modular unit is arranged to be disposed in the freeboard zone of a cleaning or degreasing apparatus that uses a volatile solvent. The freeboard zone chiller positioned above the vapor zone and the primary condenser to recover solvent from the relatively less dense solvent/air mixture escaping above the primary condenser and is formed so as to be disposed along one side of the degreaser vessel rather than on all four sides to minimize the obstruction of access into the vapor zone. This one-sided single freeboard chiller positioned on but one side produces a vapor suppression blanket that is effective and is readily retrofitted on existing apparatus without the need for dismantling of the existing unit.
