Shutting down#

  1. Stop hydrogen production at the HXB-V1 units.
  2. Let the dryer depressurise through its vents. Confirm on the control PC that the outlet pressure reads zero.
  3. Switch off at ON/OFF and remove the power cord.
  4. Disconnect the tubing and cap every gas port straight away.

Storage after use#

  • Store as described in the Receiving and storage chapter: indoors, dry, frost-free and with all ports capped.
  • Before restarting after a long stop, expect one or more full regeneration cycles before the outlet reaches its dew point.

Return and disposal#

Contact HydroXpand before returning a unit. The adsorbent and the electronics are disposed of separately; we take the unit back for this.
