Dr . Reiter concludes : “ The technology solutions from BUTTING CryoTech play a key role in the transition towards hydrogen as a sustainable and clean energy source . Cryogenic and high-pressure storage of hydrogen is essential for many applications to ensure high energy densities . These energy densities are crucial if hydrogen is to be used as a fuel in zeroemission trucks .”

About BUTTING CryoTech
Founded in 1899 , BUTTING CryoTech ( formerly Schwanner ) has evolved into one of the globally leading MSEs specialising in cryogenic technology . Since 1984 , the family-owned business has been manufacturing vacuum insulated transfer systems and valves for cryogenic gases . In 2021 , Schwanner GmbH became a full member of the BUTTING Group and has been operating under the name BUTTING CryoTech since 2023 . Located in the Upper Bavarian rural district of Altötting , the company primarily offers the following production and engineering services :
• Vacuum insulated piping ( VIP )
• Skid solutions
• Valves and couplings for cryogenic applications
• Apparatus construction in accordance with EN 1090 and WHG ( German Federal Water Act )
Standardised vacuum insulated piping ( VIP ) Transfer lines combine vacuum and multi-layer insulation for minimum heat ingress and maximum efficiency when transporting cryogenic fluids . Integrated compensators , absorption material and spacers with the lowest thermal conductivity ensure safety and durability . In addition to standard lines , the company ’ s areas of expertise include :
• Transfer systems for trailers ( LH 2 , LN 2
, LOx , LHe , LAr )
• Hydrogen systems for the automotive industry
• Refuelling systems for the aircraft and aerospace industries ( H 2 and O 2
)
• Special components ( e . g ., neon tanks )
BUTTING products
• Transfer lines for LH 2 , LN 2
, LOx , LHe , LAr
• Inner pipe diameter from 1 / 2 ” ( DN10 ) to 32 ” ( DN1000 )
• Pressure grades : PN 10 / 25 / 40 / 63 / 83 ( bar )
• Standard configurations include inside compensators
• High-pressure systems feature outside compensators
• Rigid pipes and flexible hoses
• Plug-in Johnston couplings or welded spool connections
Customer benefits
• Minimum heat impact of around 3 W / m 2 for rigid lines
• Each prefabricated spool is fully vacuum insulated ( high vacuum of 10 -5 mbar )
• VIP spools with He-leak test 10 x 10 -8 mbar and gas pressure test
• Individual spools can be connected via two different coupling types :
• Johnston – plug-in coupling
• Welding coupling
• Manufacturing code compliant with PED and ASME regulations
