  • Click Dept. name for pictures, as they are made available. (The existing pictures need to be updated.) *

    * (The white helium recovery gasbags pictured have been replaced with the original style black gasbag.
    It was found the white gasbag material allowed permeation of N2 and H20 into the recovery system and
    was continually destroying the 1st stage of our Bauer helium compressor. The sticky cord flange seals
    have also been replaced with a special RTV suitable for these materials.) ~ Ed Dreier/Mgr.

    Satellite Helium Recovery Systems On-line ~ By Dept. (with some pictures):
  • All Remote and Satellite Systems return to the Main Recovery System in the Engr. Hall.

    DO NOT USE THE WHITE GAS BAGS SHOWN IN THE PICTURES!
    THEY ARE NO GOOD FOR HELIUM RECOVERY!
    We replaced the gas bags, but have not yet replaced the pictures.
