Exlcusive images from inside the Bühlmann Druckkammer 46 years later
As reported in episode 5 of the Bühlmann story , the old hyperbaric chamber of the University of Zurich, built in 1963, met the requirements for a modern laboratory less and less. The diving depth was limited to 300 meters. The space was also limited, especially with regard to the treatment of accident victims. There was also no water tank in which diving missions in the water could be simulated. In addition, there was no efficient helium cleaning and recovery system.
In 1975 a new overpressure chamber was designed for an overpressure of 101ata, which corresponds to a depth of 1,000m.
Here some unique pictures of depth tests in this chamber and in the water tank of the chamber:
