Where HDRX cylinders and MEYER regulators fly today. Every application gets the same platform — Type IV PET-lined, sealed-liner options with no measurable permeation, EU origin, ITAR-free.
Fuel-cell UAVs
161 g of hydrogen in the 2.8 kg HDRX-068-H2 — about 5.3 kWh of usable energy, CE marked to EN ISO 12245:2022. Paired with an HDRX-R regulator configured to the stack’s inlet window, the cylinder and regulator arrive as one assembly with one mass budget. Fitted configurations exist for IE-SOAR, Aerostak, Protium and Honeywell stacks.
Application note →HDRX-068-H2 →UAV regulator →Space — CubeSats & launch
Cold-gas propellant and pressurant storage where every gram is mission mass. Sealed-liner helium cylinders with no measurable permeation, verified by helium leak detection — from 0.5 L flight bottles to 350 L stage tanks. EU origin and ITAR-free: no export-control chain in your satellite’s paperwork.
CubeSat note →Launcher note →Helium cylinders →Lighter-than-air & HAPS
Airships, aerostats and high-altitude platforms carry their helium reserve for months — permeation is lost lift and lost budget. Sealed-liner storage holds the reserve, and a MEYER regulator meters make-up gas at the envelope’s working pressure.
Helium regulator →Helium cylinders →Defence — EOD & MCM diving
Non-magnetic by construction: composite cylinders in dedicated -MIL configurations for mine-countermeasures and EOD diving, matt black, from the 0.55 kg HDRX-008-MIL. Verification per national military authorities.
