A technique for condensation soldering of articles (29) in a facility (40 or 80) having a vapor chamber (42) and a pair of aligned input (102) and exit (104) throats. An article (29) to be soldered is transported sequentially through the input channel (56), the vapor chamber (42) and the output channel (58). Simultaneously, air is moved, in a controlled manner, into and through a portion of the exit channel, in a direction opposite to the movement of the article and withdrawn from the input channel. The air exiting the input channel is processed to recover the expensive vapor entrained therein.
