Hi everyone,

My lab is moving to a new building and I have replaced the air cooled
helium compressor of a Bruker 800 system to the water cooled version since
there is no place outside of the new building for the outdoor unit. The
original outdoor unit FA-70 has been working fine without any issue. I
cleaned its heat exchanger regularly, and its indoor unit has been
maintained under CP10K contracts. The whole thing includes the outdoor
unit, the indoor unit, and 10 meter supply and return flexlines.

If anyone is interested, please feel free to contact me. Attached a few
pictures.

Thanks,
Daoning
