Nomad Series
Compact Type III COPVs
Lightweight composite pressure vessels for compact, mobile, marine and space-constrained gas-storage applications.
The Nomad Series brings together Steelhead's compact Type III composite overwrapped pressure vessel platforms for applications where packaging, weight, mounting and integration flexibility are central design requirements.

Compact pressure vessel platform
Three compact Type III platforms for different integration strategies.
Nomad Series products are designed for systems where vessel geometry, weight, mounting and port configuration can drive the overall package.
Trek supports compact 3000 PSI gas storage with flexible lengths and manifold options. Ranger is a 350 bar neck-mount platform built around a compact 6.7-inch diameter. Tide is a compact 3600 PSI CNG platform positioned for marine and other space-constrained CNG applications.
Nomad Series products
Choose the compact vessel around the application.
Trek, Ranger and Tide share a lightweight Type III approach while serving distinctly different pressure, mounting and application requirements.
