Abstract
A unique purge system for a two heat exchanger RTO system uses separate purge valves associated with each of the first and second heat exchangers. In this way, the purge valves allow strict control over the flow of clean gas through the purge valves and into the heat exchanger. The inventive system insures that the two RTO systems can continue to operate efficiently and safely, while insuring that no dirty gas will reach the outlet passages.
