Mission
Deliver reliable catalyst and gas purification technology that protects downstream processes, product quality and the environment.
About Us
A specialist company in catalysis and ultra-high-purity gas purification.
Founded in 2005 in Dalian, Kaiteli combines catalytic engineering research heritage with hands-on process engineering to deliver custom-selected catalysts, adsorbents, desulfurizers and ultra-high-purity gas purification systems for demanding industrial users worldwide.
Company profile
Dalian Kaiteli Catalytic Engineering Technology Co., Ltd. is headquartered in the Dalian High-Tech Industrial Zone, Liaoning, China. The company designs, manufactures and delivers industrial catalysts, adsorbents, desulfurizers, DeNOx catalysts, VOC catalytic combustion catalysts and ultra-high-purity gas purification systems.
Our team combines catalytic engineering research, chemical process design and mechanical engineering — allowing us to select and engineer complete solutions rather than sell products from a catalog. We serve petrochemical companies, industrial gas producers, semiconductor gas users, EPC contractors, hydrogen producers, environmental integrators and specialty gas houses across more than thirty markets.
Kaiteli operates under an ISO 9001 / 14001 / 45001 integrated management system and supports global customers with export-compliant documentation, technical data sheets, safety data sheets and long-term regeneration and replacement services.
