What We Do Leading the way with innovative out-of-the-box solutions.

  • Engineering Cylinders with Passion

    No one knows the day tomorrow – but at Meyer CD we have an excellent example of how the future solutions for a high-pressure cylinder should look.

  • Lightweight Material Engineering

    We are constantly on track and up to date. This means that we can always provide you with a professional and serious advice based on your particular cylinder/regulator situation.

  • Solutions

    Since we are all moving in a dynamic world, the solution today is not necessarily the right solution tomorrow. Therefore it is crucial that your choices are based on consideration and documentation – with the clear objective to promote the viability and functionality of your project, thus giving you a competitive advantage.

  • Light and thin – Yet Rock Solid

    MEYER CD develops reliable solutions perfect for aviation, Fuel-cell powered drones, laboratory testing, aerospace, rockets and satellites. These solutions combine requirements for high pressures, compact designs and low weight. We have provided competitive advantages for customers and drone owners.

About MEYER CD

MEYER CD designs, qualifies, and manufactures ultra-lightweight composite overwrapped pressure vessels (COPVs) and HDRX-series high-pressure regulators for the most weight-critical applications in aerospace and unmanned systems. The HDRX cylinder family covers volumes from 0.5 L to 350 L at working pressures up to 700 bar — Type IV PET-lined construction with carbon-fibre overwrap, qualified to ISO 11119-3, EN 12245, TPED 2010/35/EU, and PED 2014/68/EU as appropriate to each application.

Our cylinders are flying today on hydrogen fuel-cell drones, CubeSat cold-gas thrusters, and orbital launch vehicles. Compared with all-metal cylinders, MEYER COPVs are up to 70% lighter; compared with Type 3 aluminium-lined alternatives they are up to 45% lighter — savings that translate directly into flight time, payload capacity, and orbital payload mass. The HDRX-R450 high-pressure regulator complements the cylinder line for fuel-cell and propulsion integration with hydrogen-embrittlement-resistant 316 SS construction and configurable single- or two-stage regulation.

Where to start

  • COPV Selector — match working pressure, cycles, mass and permeation to the right format across all five COPV types.
  • COPV catalog — 36 production cylinders with searchable specs, dimensions, certifications, and direct order forms.
  • Mass calculator — estimate cylinder mass for your volume, pressure, and safety factor; compare Type IV against metal alternatives.
  • Applications — MEYER COPVs and regulators in UAV, CubeSat, and launch programs.
  • Regulators — HDRX-R450 and custom high-pressure regulator engineering.
