Our Vacuum Jacketed Hose Assemblies are the most cost effective and thermally efficient method of transferring liquefied gases:•Nitrogen•Hydrogen•Oxygen•Carbon Dioxide•Helium•Argon•Other Natural GasesVacuum Jacketed hose is two pipes in one, an inner-carrier hose in which the cryogenic liquid is transferred and an outer-hose that supports and seals the vacuum. The inner-hose is wrapped with a multi-layered super insulation that prevents radiative heat transfer.The annular space between the inner-hose and the outer-hose is evacuated, preventing convective heat transfer. The resulting hose is the most efficient transfer system available for cryogenic liquids.Benefits:•SafetyoOuter surface is safe to touchoReduces frost, hazardous ice and dripping water•Lower CostoReduced cryogen lossesoReduces maintenance costsoHighest quality liquid delivered to the use point•DurabilityoUp to 20 year vacuum integrityoHose assemblies designed to ASME/ANSI B31.3 standards•Customizableo¼” - 6” inner hoseo150 psi standard design with higher pressures availableoLong lengthsoA full assortment of end fitting options
