What Aerix does

Aerix (에어릭스) is a South Korea-based industrial environmental equipment provider founded in 1976, specializing in air pollution prevention systems for heavy industry, power generation, and small-to-medium industrial facilities. The company designs, fabricates, installs, and maintains a comprehensive product portfolio including bag filters and electrostatic precipitators for dust collection (with proprietary VIP and MPB technologies patented across multiple countries), RTO/RCO systems for VOC removal (98%+ removal efficiency, 95% heat recovery), and flue gas treatment systems for denitrification (SCR/SNCR), desulfurization, and incineration. A growing IoT segment anchored by the Thing ARX platform and IEMS monitoring system provides real-time equipment data and predictive maintenance capabilities, with 122 smart dust collectors deployed at POSCO facilities achieving documented 9.6 billion KRW in annual energy savings.

The company generates revenue through project-based equipment sales for large-scale industrial installations (primarily steel mills, power plants, petrochemical facilities), ongoing O&M services with monthly payment options, consumables (proprietary GPS filter bags manufactured by subsidiary Aerix F&C), and a nationwide IoT device distribution network targeting small and medium facilities newly subject to Korea's mandatory IoT monitoring regulations. Key customers include POSCO (with dedicated on-site offices inside Pohang and Gwangyang steel mills), Korea Zinc, Doosan Heavy Industries, SK Construction, and Kumho Petrochemical. Aerix operates a direct enterprise sales model with dedicated sales personnel assigned by product category, supported by government-supported installation programs for small facilities where installation costs are covered up to 90% by public subsidies. Registered capital stands at 67.5 billion KRW, the workforce has grown to approximately 550 employees as of October 2025, and 2022 revenue reached 740 billion KRW.

Technology development is supported by industry-academia partnerships with POSTECH, GIST, KAIST, UNIST, and the Korea Institute of Energy Research, along with technology licensing from Hitachi, Termokimik, and LTA. The company has expanded its IoT platform through the KETI partnership for OneM2M-based standardization with planned machine learning integration. Recent strategic positioning includes achieving medium enterprise status in 2022, obtaining Fair Trade Commission AA grade certification in 2024, and aligning product strategy with the January 2025 Clean Air Conservation Act mandate requiring IoT device installation at Class 4-5 air emission facilities.
