摘要：A method and apparatus for vapor conservation and control for use with vaporphase 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 fromthe processing tank and cooled to condense the vapor, and the remaining air is thenreturned to the tank above the area of withdrawal. A negative pressure is preferablycreated at the tank entrance such that air flow is into the tank to prevent emission ofvapor and pollutants from the tank into the atmosphere.
