The small one is the buffer tank.Last q, buffer tank was the small one or the hugeee one?
Without your input, it would have taken alot more trial and error. Thanks again.Actually you did all the heavy lifting so to speak,
I still have a little work to do to the charge, the system is slightly unstable with this charge. I believe I added to much 740. The high side slowly creeps up in pressure until it trips the dump valve. The system will warm up to -134C and will get back down to -153C over time. I believe one more recovery and charge will get it.
I also wanted to say thanks to the other members here who have worked with autocascades, for posting their threads for others to read. The information that I have found in them have been invaluable in this little endevor.
Yes that is safe to say. The perscribed way to store a large amount of samples is to cool in stages (-20Cto -80C to-150C) or use LN2. These systems are not designed for large loads of heat removal.If this is for sample storage, is it safe to say the unit is tuned for very low heatloads?
