• Various hazardous substances, known as AMC*, present in cleanrooms for semiconductor and display manufacturing processes can reduce product yield and pose health risks to workers. With the rapid advancement of the AI industry, high‑density integration in the IT sector—including semiconductors—has accelerated, making the removal of harmful contaminants in cleanrooms increasingly critical.
• Ecopro HN is developing high‑performance adsorbents and chemical filters required to improve air quality in electronic manufacturing cleanrooms as well as in living environments, through continuous technological advancement. In line with its commitment to environmentally responsible management, the company is actively focusing on the development of ESG‑oriented products.
  * AMC (Airborne Molecular Contamination): A collective term for airborne contaminants such as volatile organic compounds (VOCs), acidic and basic gases, and ozone.

An intelligent environmental solution that significantly reduces initial response time in the event of contamination in cleanrooms. By patrolling autonomously, the robot continuously senses chemical substances and enables early detection of contamination compared to fixed sensors. Equipped with a configurable multi‑filter system, it performs targeted purification based on the type of contamination.

Key Features

• Sensing (Precision Real‑Time Monitoring) : Equipped with high‑precision temperature, humidity, and gas sensors, the system continuously monitors VOCs, NH₃, and acidic gases in real time. Upon detecting contamination, the purification algorithm is immediately activated, enabling rapid response.
• AI AMR (Autonomous Cooperative Navigation) : Based on 3D LiDAR SLAM and high‑precision local mapping technologies, multiple robotic units are linked to a centralized control system and navigate via the shortest route to contamination sources.
• Active Purification (Advanced Filtration) : Utilizes an integrated multi‑layer filter design (e.g., sandwich layer structure) to enable customized responses to specific contaminants. With high‑capacity airflow control, the system achieves up to 99% purification efficiency.

• Greenhouse gas and air pollutant reduction catalysts are core environmental technologies that effectively mitigate harmful gases generated across a wide range of industries, including semiconductors, displays, secondary batteries, petrochemicals, power generation, steelmaking, and shipbuilding.
• Ecopro HN leverages proprietary technologies to design, develop, and apply high‑efficiency catalysts and various air pollutant reduction catalysts tailored to the specific requirements of each industry. Beyond regulatory compliance, the company continues to advance catalyst technologies through ongoing research and development to enhance customer value and further improve catalyst performance.
