Abstract
A method and apparatus for vapor conservation and control for use with vapor phase soldering, degreasing, or similar systems having a tank into which work is introduced and removed. The air present above the processing vapor zone is drawn from the processing tank and cooled to condense the vapor, and the remaining air is then returned to the tank above the area of withdrawal. A negative pressure is preferably created at the tank entrance such that air flow is into the tank to prevent emission of vapor and pollutants from the tank into the atmosphere.
