Overview

Oxygen-clean by design, not by afterthought.

Oxygen is indispensable in aerospace, defence, medical, and industrial systems, but it is also one of the most unforgiving media to handle — even microscopic contamination or design flaws can trigger ignition at high purity and elevated pressures.

The Oxygen Component Test Benches are purpose-built platforms that deliver complete qualification, acceptance, and R&D testing of every oxygen system component: regulators, valves, flow meters, instruments, masks, safety devices, and integrated assemblies. These benches are designed and manufactured in line with ASTM, NFPA, ISO, and CGA standards, ensuring both operator safety and component reliability.

Unlike generic pressure rigs, these are designed from the ground up for oxygen compatibility, incorporating oxygen-clean assembly (ASTM G93 / CGA G-4.1), helium mass-spectrometer leak testing (≤1×10⁻&sup6; mbar·L/s), and built-in safety systems such as slow-fill orifices, particle filters, and integrated relief regulators.

Cleanliness first. Safety by design. Leak-tight integrity.

The test benches are built around three non-negotiable principles: Cleanliness First — all wetted parts are oxygen-cleaned, double-bagged, and validated via particulate/NVR checks and UV hydrocarbon inspection; Safety by Design — integrated relief valves, slow-fill orifice restrictors, high-efficiency particle filters, gas detectors, E-stops, and SCADA alarms; and Leak-Tight Integrity — every component undergoes helium leak detection and final assemblies are tested for creep, lock-up, and tightness.

System Architecture

Six systems, one qualification suite.

Every subsystem of the Oxygen Component Test Benches is engineered around oxygen compatibility, leak-tight integrity, and full traceability of test data.
