A twin tower gas drying system is disclosed for filtering unpurified gas to supply purified gas to a pneumatic system. The drying system includes a separator, two coalescers, two desiccant towers and a mechanism for controlling flow of unpurified and purified gases therethrough. The separator separates moisture and other particulates from the unpurified gas. Each coalescer removes moisture remaining within the unpurified gas. A first tower removes moisture remaining within unpurified gas received from a first coalescer to provide a first stream of purified gas. A second tower removes moisture remaining within unpurified gas received from a second coalescer to provide a second stream of purified gas. The flow controlling mechanism enables the drying system to alternately (i) extract moisture from unpurified gas passing through the first coalescer and tower to supply the pneumatic system with an output percentage of the first stream while purging moisture both previously collected in the second tower and coalescer by passing a purge percentage of the first stream through the second tower and coalescer and expelling the remoisturized gas to atmosphere via the mechanism and (ii) extract moisture from unpurified gas passing through the second coalescer and tower to supply the pneumatic system with the output percentage of the second stream while purging moisture both previously collected in the first tower and coalescer by passing the purge percentage of the second stream through the first tower and coalescer and expelling the remoisturized gas to atmosphere via the mechanism.

A twin tower gas drying system for cleaning and drying a stream of unpurified pressurized gas received from a source thereof for use by a pneumatic system, said gas drying system comprising: (a) a means, disposed within said gas drying system, for initially separating from such stream of unpurified gas moisture and other particulates suspended therein as such unpurified gas flows through said separating means; (b) two coalescing elements each of which for removing moisture remaining within such stream of unpurified gas flowing from said separating means; (c) a first tower having a first desiccant material therein for removing moisture remaining within such stream of unpurified gas received from a first of said coalescing elements so as to supply a first stream of purified gas therefrom; (d) a second tower having a second desiccant material therein for removing moisture remaining within such stream of unpurified gas received from a second of said coalescing elements so as to supply a second stream of purified gas therefrom; and (e) a means for controlling flow of such unpurified and purified streams of gases through said gas drying system such that said gas drying system alternately switches between (i) extracting moisture from such unpurified gas passing through said first coalescing element then through said first desiccant material so as to supply such pneumatic system with an output percentage of such first stream of purified gas while purging moisture both previously collected in said second desiccant material and in said second coalescing element by passing a purge percentage of such first stream of purified gas through said second tower then through said second coalescing element and expelling such remoisturized gas to atmosphere via said means for controlling flow and (ii) extracting moisture from such unpurified gas passing through said second coalescing element and then through said second desiccant material so as to supply such pneumatic system with an output percentage of such second stream of purified gas while purging moisture both previously collected in said first desiccant material and in said first coalescing element by passing a purge percentage of such second stream of purified gas through said first tower then through said first coalescing element and expelling such remoisturized gas to atmosphere via said means for controlling flow.
