Engineering & compliance
How industrial systems are specified and released
Gas generation performance, air quality, and pressure equipment compliance — for industrial buyers.
Industrial equipment only. Not for medical devices or FDA-regulated clinical applications.
By product family
Industrial nitrogen & oxygen
Performance basis is flow, purity, delivery pressure, and duty cycle. TriEquion™ (N₂) and MBVD™ (industrial O₂) multi-bed cycles target energy and stability versus conventional twin-bed PSA. Medical/USP claims are not used in U.S. materials.
Instrument air & TBAD™ dryers
Specified to dew point and ISO 8573 class targets. Packages include filtration and optional carbon treatment. Dryers use tri-bed adsorption for stable dew point and reduced switching losses.
ASME Section VIII vessels
Process vessels and receivers designed to client design P/T, materials, and corrosion allowance. Nameplate data, NDE, hydrotest, and MDR packages defined at bid stage.
Corporate structure & manufacturing
Zenox USA is a subsidiary of Zenox Australia (Zenox Gas Systems Australia Pty Ltd). Equipment is Zenox-engineered with Oxair India fabrication — gas systems, dryers, and pressure equipment under controlled manufacturing and quality systems (ISO 9001).
What we deliberately do not pursue (U.S.)
Keeps sales, engineering, and compliance focused.
- Medical / hospital oxygen generators
- FDA 510(k) or medical device submissions
- USP / pharmacopeia medical gas positioning
- Veterinary clinical oxygen as a device product
- Any claim that on-site gas is a medical device
Pressure equipment controls (vessels & receivers)
| Stage | Typical controls |
|---|---|
| Design review | Code path, design conditions, materials, CA |
| Drawing approval | GA, nozzle schedule, nameplate data |
| Material receiving | MTR check, identification |
| Fabrication | WPS compliance, in-process checks |
| NDE | Per drawing class and hold points |
| Hydrotest | Witness/hold as per ITP |
| Documentation | MDR completeness before shipment |
Typical deliverables
Gas packages and vessels — adjusted to purchase order scope.
