Gaspure Chamber Gas Recovery

Gaspure Chamber Gas Recovery


The Divex Gaspure Chamber Gas Recovery System purifies diving chamber or habitat gas and allows chamber gas recovery during operations rather than venting to atmosphere and losing the expensive helium.

Gas is routed from chamber exhausts, medical and equipment locks and trunking via piping to a gasbag.  From there it is drawn by a gas transfer compressor through the Gaspure purifier system before being routed to clean gas stowage for re-use.

The Gaspure removes all reactive contaminants such as water and oil vapour, CO2, CO, H2S, SO2, NOx.

The system comprises of:

  • Gaspure Purifier System (with 8 stages of purification)
  • Gasbag (840 cu / ft as standard, other sizes available on request)
  • Gasbag Controller
  • Alarm Panel
