• All-in-one simultaneous abatement of VOC and NOx
  • Existing CTP RTO systems can be equipped with NOx control
  • Specially designed injection lances and distribution system


The VOCNOxTherm system combines low operating costs and excellent cleaning efficiency of an RTO with the NOx reduction of an SNCR. In several applications the VOCNOxTherm eliminates the need for an additional and complete SCR system.



  • High VOC cleaning efficiency 
  • CTP’s honeycomb ceramic heat exchangers
  • Very high thermal efficiency 
  • Low pressure drop (<30 mbar)
  • NOx reduction up to 60%
  • High availability
    • Weatherproof installation of instrumentation and heating system
    • Field proven advanced software
  • Possible retrofitting of an existing CTP RTO system for NOx removal
  • High dust tolerance


Available options:

  • Free choice of the reduction agent (ammonia, urea)
  • Gas and liquid injection
  • Electric heating
  • Hot and cold bypass
  • Online bake-out
  • Integrated as well as separate raw gas preheating
  • Heat recovery
  • Automatic cleaning
