Look at General Air Products of Exton PA.  They make a "Dry Air Pac".  Works
well, we have installed several in critical locations where we do not want
any moisture in dry or pre-action systems.  None better.

Subject: RE: Air Dryer

Most air dryers are designed to work best at cooler ambient and compressed
air temperatures (office temperatures are ideal). If that is not available,
pre-cooling the compressed air is advisable. If dryer is mounted outside or
in hot area you might get longer life out of the dryer by using one that has
a larger capacity than the compressor is capable of producing. Any
manufacturer is able to size a dryer for ideal conditions.
