Revolutionizing Tunnel Air Quality: Heesung Catalysts’ Purification System for Sustainable Urban Infrastructure
2021.04.18
As cities worldwide prioritize sustainable infrastructure, improving air quality in underground spaces has become a critical challenge. Heesung Catalysts provides an advanced catalytic solution that enhances air purification efficiency in tunnels and urban transit systems.
Application of Heesung Catalysts’ Technology
The Seoul Jemulpo Tunnel and Seobu Expressway Underground Road, both opened in 2021, feature air purification systems incorporating Heesung Catalysts’ technology to effectively reduce harmful gases and improve tunnel air quality.
This system operates through a three-stage purification process:
- Primary filtration captures large particulate matter (PM).
- Electrostatic precipitators remove fine and ultrafine particles.
- Heesung Catalysts’ system converts harmful gases such as CO₂ and NO₂ into harmless substances, enabling clean air recirculation.
This technology is adaptable for various urban infrastructure projects, including:
- High-traffic urban tunnels and underground highways.
- Subway ventilation systems.
- Smart city air quality improvement initiatives.
The Role of Heesung Catalysts’ System
Heesung Catalysts’ technology enhances tunnel air purification by addressing both particulate matter and gaseous pollutants.
- Harmful gas reduction – Effectively removes CO₂, NO₂, and other pollutants.
- Enhanced air purification efficiency – Works in conjunction with filters and electrostatic precipitators for optimized air quality.
- Long-term stability & cost efficiency – Maintains catalytic performance over time, reducing maintenance costs.
With increasing global air quality regulations, Heesung Catalysts’ proven technology is contributing to cleaner and safer tunnel environments.
As urbanization accelerates, the demand for improved underground air quality continues to rise. Heesung Catalysts remains committed to maximizing the effectiveness of air purification systems through cutting-edge catalyst technology, supporting the development of sustainable urban infrastructure.
