CRANE® CRYOFLO™ Vacuum Jacketed Storage Tank Fill Manifold is ideal for transferring liquid hydrogen (LH2), liquid nitrogen (LN2) and other cryogenic liquids from storage tanks, as it reduces heat loss and evaporation. The manifold is made of stainless steel and has a vacuum jacketed inner pipe that insulates the cryogenic liquid from the ambient temperature.

Features And Benefits

  • Performance: Innovative engineered design greatly reduces Hydrogen loss through improved heat transfer and enhanced CV.
  • Lead Time: Automated facility delivers products faster and more efficiently with consistent quality.
  • Bespoke Solution: CRYOFLOTM offers full customization and engineering for any tank layout.
