This system delivers stable performance even if the lad varies.
- This system removes nitrogen dioxide(NO2) contained in the air emitted from tunnels or underground parking.
- Dry absorbent can absorb NO2 chemically.This system delivers stable performance even if flow velocity of air to be treated and NO2 density vary. The absorbent can be recycled by regenerating the deteriorated absorbent.
- This system includes no heating or pressurising process which may cause a fire or an explosion. Full automatic operation is made possible. The wastewater generated in the regeneration process of the absorbent is discharged after denitrification .
