Dearest wizards of AMMRL,
Previously I was using a room temp BBO probe and it would cool quite quickly
to -25 to -30C with the same setup. We've recently had our long awaited
Prodigy installed and now it won't get below -5C (corrected) with the VT
gas up to 800 lph.
Further details: I have a BBO Prodigy with a BCUII chiller. My air is dried
to -80C dew point and flows through a nitrogen separation membrane to provide
VT gas.
Any suggestions?
Thanks
