CBS Vessels - Life of vacuum/pump down option
We have a couple of CBS vessels that we believe need to have pumped down to restore the vacuum. We believe them to be about 15 years old. They are losing three inches of LN every day. The lids and seals are fine and all solenoids are working as they should.
Has anyone experienced this before and is it possible to pump these vessels down?
Any help greatly appreciated.
