Cryogenic Air Separation Units for High Purity Oxygen, Nitrogen, and Argon
SIAD offers a comprehensive line of custom-engineered and standard-design air separation plants that produce high-purity medical and industrial-grade oxygen, nitrogen, and argon through the cryogenic distillation of atmospheric air. Our air separation units (ASU) are meticulously designed and built to the most rigorous engineering and manufacturing standards, utilizing SIAD’s cutting-edge technology developed over 75 years of expertise in cryogenic process equipment.
With a global footprint, SIAD has successfully delivered more than 600 ASU units to industries such as electronics, chemicals, petrochemicals, food and beverage, steel production, glass manufacturing, pulp and paper, and industrial gases.
Our product line includes:
- Custom-Engineered Gas Plants
- Merchant Liquid Plants
- Nitrogen Gas Generators
- Oxygen/Nitrogen Liquefiers
Air Separation Unit Production and Purity Range
| ASU PRODUCTION AND PURITY RANGE | ||
|---|---|---|
