Multi-stage solution for particulate, acid/base, and solvent emissions.
Multi-Stage Chemical Processing
Supports cascade neutralisation across multi-gas inputs.
Challenges vs TNBi's Solutions
How It Solves Your Top Scrubber Challenges
“Too many pollutants, need multiple systems”
Cyclone + Venturi + Packed Bed + Demister: all in one unit
“Our exhaust is over 900° C”
Withstands ≤ 1100°C inlet temp without needing pre-cooling
“Corrosion, clogging, and noise issues”
Abrasion/corrosion-proof internals + low-noise operation
