ABSTRACT:
A treatment cell for spraying two phase treatment fluid on a continuously moving strip work product is enclosed within an air impervious containment chamber having ingress and egress openings to receive and discharge the work proudct. Air knives in the containment chamber receive air under pressure from a blower and this air strips any residual treatment fluid from work product at the chamber entry and egress openings. The air blower is within the chamber and the only air used through the air knives is continuously recycled entirely within the chamber. Cooling coils low in the chamber condense some of the vapor phase treatment fluid from the air in the container and all of the liquid phase of the treatment fluid flows by gravity to a sealed sump for reuse in the treatment cell.
