Hi everyone,
This is about dry air/nitrogen again....
I have looked at archived messages back to 2007 and found some good posts.
Decided to follow up on two subjects: (1) refrigeration dryers, (2)
boiloff N2 systems
(1) Are you using a refiregeration drier?
Would you mind responding with the following:
brand model ~cost to purchase cost of maintenance per
year dewpoint flow capacity pressure range
Any additional comments...?
(2) I've tried hooking up "gas use" nitrogen outlet of high pressure
liquid nitrogen tank.
supposedly N2 gas obtained that way must be very dry.
However apparently it is worse then -50C dewpoint as our air chiller
clogged up after ~14 hours.
Would you have any suggestions of proper practices that could make
this setup work?
(my setup is: tank->pressure regulator->12m 1/4inch plastic tubing->VT
air system)
Have you had any gotcha moments with a setup like that?
Thank you very much.
Evgeny.
