Hello everyone,
My apologies if this question has already been asked before.
We recently had the 10,000 hour cryoprobe service on our old TCI-cryoprobe.
During the maintenance, the Bruker service engineer noted that the
helium compressor has already logged over 92,000 hours of operation, and
that before the next regular maintenance we will cross the 100,000 hour
milestone (assuming no catastrophic failure).
He gave me the impression that many helium compressors fail long before
they reach this milestone.
So, I wanted to ask the community about your experiences with helium
cryoprobes (or more generally helium compressors).
My questions are:
* How long has your helium compressor been operational?
* Have you suffered a helium compressor breakdown?
* And are there any telltale signs that the failure is imminent?
* How expensive is it to repair/replace?
I am also worried about our newer helium compressor. In that case, it
has about 50,000 operational hours. But two years ago it suffered
frequent unscheduled warm-ups due to issues related to the chilled water
in that building.
I would greatly appreciate any experience you can share. I will be sure
to post a summary.
Thanks,
Bob.
