What is a COPV?
A COPV (composite overwrapped pressure vessel) is a high-pressure gas cylinder built by overwrapping a seamless aluminum liner with full carbon fiber — delivering maximum strength at minimum weight for demanding programs such as satellite ground testing.
COPV Applications in Satellite & Space Programs
Acecare COPVs serve development and ground-test programs across the space industry:
- Satellite propulsion ground testing — high-pressure gas supply for satellite propellant tank and pressurant tank test campaigns.
- Pressurant / propellant storage for test rigs — stable 4500 PSI storage for ground support equipment and propulsion test stands.
- Cold gas thruster development — clean, dry high-pressure gas for cold gas thruster prototyping and qualification testing.
- CubeSat test articles — lightweight composite overwrapped pressure vessels sized for CubeSat-scale propulsion test articles.
Why Acecare COPVs
- DOT certified — certified for safe high-pressure service.
- AA6061 aluminum liner — seamless, corrosion-resistant liner.
- Full carbon fiber overwrap — maximum strength-to-weight ratio.
- Working pressure 4500 PSI (310 Bar)
- Test pressure 7500 psi
- US warehouse (Chico / Ontario) — in-stock inventory for fast lead time.

Frequently Asked Questions
What is the minimum order quantity?
We welcome trial orders starting from a single unit — ideal for test articles and development programs.
What is the lead time?
In-stock items ship quickly from our US warehouse (Chico / Ontario). For bulk or custom orders, contact us for current availability and lead time.
Can you customize sizes or valves?
Yes. Beyond our standard 6.8L configurations (tank only, normal valve, or dual gauge fill station valve), we can discuss custom sizes and valve options for volume programs.
Do you provide a datasheet?
Yes — email us at [email protected] and we will send the product datasheet and DOT certification documents.
