APPARATUS AND METHOD FOR REDUCING SOLVENT LOSSES

摘要

A volatile solvent conservation modular unit and method for effecting solvent conservation is provided. The cooling coil modular unit (11) is arranged to be disposed in the freeboard zone of a cleaning or degreasing apparatus (10) that uses a volatile solvent. The freeboard zone chiller (11) is formed so as to be disposed along one side of the degreaser vessel rather than on all four sides. This one-sided freeboard chiller produces a vapor suppression blanket that is surprisingly effective compared to structures which ring the entire opening, and it is readily retrofitted on existing apparatus without the need for factorytrained installers.
