Ice in my Halt chamber
Ice in my Halt chamber
(OP)
Hi all,
We have a QualMark Halt & Hass chamber here at my work. I can't seem to figure out how all the moisture is getting into it. When we take it down below zero C it ices up bad. We don't have the nitrogen purge hooked up but the other guy figures that after a while the LN2 used to cool the chamber should have driven out the moisture anyway. The website wasn't very much help. Does anybody know if the chamber is sealed on these usually and the LN2 goes through a heat exchanger or is it shot directly into the chamber?

Also I doubt your compressor air is anywhere near as dry as you suppose. (is the dryer a dessicant type? Hows the media?)

Agreed. Vent the shaker table air outside the chamber.
