Dear colleagues,
Thank you to those, who responded to my email.
here a brief summary about my question:
I received only one answer with an experience that the heating in winter was lost, the problem seemed to be more the other direction (too high temperatures/lack of air conditioning). In the described case nothing happened to the NMR system.
Most of you are mentioning the problem of moisture which can condense in the electronics (console, probe, shim coils, pneumatic, etc) and that this would be mostly a problem when warming up the room. Therefore some gave the recommendation to wait a few days before switching the consoles on and flush probes and bores with dry air or N2.
One person was mentioning the seals, but he said in the same sentence, that there won’t be a problem with them.
Many thanks,
Sebastian

Betreff: AMMRL: keeping a magnet at low temperature
Dear colleagues,
let’s see, if the experience of the community can help me with my question: because of the political situation, our university needs to reduce their energy consumption and plans to close between xmas and new year with very limited amount of heating. Does someone know, if there are potential damages, which a NMR system can get, when staying at 5 °C over a week or two (consoles switched off)? Has someone experience with this? Bruker has no data to it.
Best regards,
Sebastian
