Industry briefFrom your process data to a working purification package in three steps
- 1
Submit your gas composition
Share gas type, impurities, flow rate, pressure, temperature and target outlet purity.
- 2
Get product selection advice
Our engineers recommend a suitable catalyst, adsorbent or purification package.
- 3
Receive quotation and technical support
You receive commercial terms, TDS and full engineering support throughout the project.
A catalyst and gas purification specialist — not a distributor.
Every recommendation is engineered from your gas composition, impurity levels, flow rate, pressure, temperature and outlet purity requirement. From ambient desulfurization to ultra-high-purity purification, Kaiteli owns the catalysis, the equipment engineering, and the after-sales support.
- Catalytic engineering background rooted in Chinese national research institutes
- Custom-selected catalyst / adsorbent / purifier based on your process data
- ISO 9001 / 14001 / 45001 quality, environment and safety management
- Global export experience — packaging, documentation and export compliance
- Full lifecycle — selection, supply, commissioning, regeneration, replacement
