Atlas Series
Type I Pressure Vessels
Modular, space-efficient all-aluminum pressure vessels for low-pressure gas accumulation and hydrogen buffer applications in ground and mobile systems.
Atlas Series vessels provide a corrosion-resistant Type I option for industrial, hydrogen, energy, test-bench and specialty-gas applications where straightforward construction and packaging flexibility matter.

Low-pressure Type I storage
A straightforward aluminum platform for buffer and accumulation duties.
Atlas Series vessels use an all-metal Type I architecture for applications where lower-pressure gas accumulation or buffering is required and a composite overwrap is unnecessary.
The family supports hydrogen buffer storage, industrial gas systems, energy equipment, test benches, specialty-gas applications and mobile installations.
