Claim Text:
1. A system for aftercooling and demoisturizing hot compressed air, comprising: a) a housing containing a plate heat exchanger (PHE) for air cooling said hot compressed air during passage therethrough, said PHE having a plurality of horizontally-oriented, substantially parallel plates, said housing having an inlet intaking said hot compressed air, an exhaust plenum portion receiving cooled air having condensed moisture from said PHE, said exhaust plenum portion positioned adjacent and external to said PHE, and an exhaust plenum outlet exhausting said cooled air from said housing; b) wherein said PHE has a bottom wall and said exhaust plenum portion has a bottom wall; and c) wherein said bottom wall of said exhaust plenum portion is positioned lower than said bottom wall of said PHE, thereby forming a recessed trough collecting said condensed moisture from said cooled air, said recessed trough having a concave inner surface and comprising moisture separating material positioned within said recessed trough, said moisture separating material reducing air flow in said recessed trough and said recessed trough reducing reentrainment into said cooled air of said collected condensed moisture.
