I am looking at drying solutions for my embryonic liquid penetrant program. I have an OEM spec before me that requires a circulating hot air dryer at 160 deg. F maximum. I have seen some pretty substantial units, but my operation is very small and would likely require about a 4 ft cubed space for anything I will be doing (not to mention my shop is very small). So, fellow forum members, where might I get the most of my time in a search?
