Abstract

An apparatus for the recovery of solvents from coated parts during the drying step which consists of a means for heating the air used to dry the parts, an insulated drying chamber, a liquid spray scrubber, a refrigeration section to condense solvent and a cross-exchanger which allows air coming into the refrigeration section to be cooled by that exiting therefrom. The cooled solvent-lean air is then passed to the heating means before being recycled to the drying step.
