Small volumes of cryogenic liquids are stored and handled in purpose built storage vessels. The two types utilised by ALH customers are;

Pressurized Liquid Vessels (PLVs)

  • Contain cryogenic liquid under pressure
  • Greatest capacity for liquid
  • Filled by trained operators of ALH


  • Non-pressurised storage vessels
  • Insulated containers with lids that can vent
  • Typically filled by PLVs by end users
