Values shown are the standard manufacturing range. Final parameters are calculated from your gas volume, dust or pollutant load, temperature and the emission standard in force at your site.

Customisation options

  • Stage combination per inlet pollutant profile
  • Retrofit layout to fit existing ductwork and structures
  • By-product handling: gypsum, wastewater and sludge
  • Bypass and shutdown strategy

Export packing & delivery

  • Modular sections with site assembly plan
  • Internals and catalyst shipped separately

Drawings, assembly sequence, manual and test records are supplied with every shipment. On-site engineer dispatch can be arranged for complete system projects.
