Excellent company! The belt-guard mounted after coolers do exactly what they claim. Our small shop has a 15 SCFM compressor. We didnt want to spend a lot of money on a dryer, but we absolutely needed dry air. The exchanger that Southwest Thermal Tech sized for us was perfect. It was easy to mount, easy to plumb, and brought our 130 PSI air to within a few degrees of ambient temp. We can now finish our air with a simple desiccant can which will last for a long time between regen. Thanks!

Good, honest company
