A simple sealed oven (at 40C) that is purged with clean nitrogen is very effective (clean N does not carry H20)at getting rid of moisture and rather inexpensive.

It is difficult to achieve 40°C and less than 5%RH when ambient RH is 50-60 percent. So, someone called and asked how long he would need to keep the parts at a pressure equivelent of 80,000 ft above sea level, temperature at room ambient to dry out parts. No one here had considered it before. The physics made me feel like I was at altitude.
