Regenerative Thermal Oxidizer (RTO)



Methods of printing and flexography are causing emission of odoriferous contaminants to the atmosphere, particularly because of the use of solvents contained in the inks and lacquers. In order to not harm the neighborhood and to comply with local environmental regulations (City of Montreal – CMM), volatile organic compounds (VOC) must be checked, cleaned and dispersed into the atmosphere.


  • Local captation and control of contaminants emitted by the processes
  • Odor control (environment)
  • Emissions treatment (VOC)
  • Atmospheric dispersion

Challenges Resolved

Dispersion atmosphérique et contrôle des émissions d’odeur | Respect de la règlementation environnementale | Optimisation des coûts d’opération | Maximisation de l’efficacité d’épuration

Optimisation des coûts d’opération en fonction des pointes d’émission de COV (très variables dans le cas des presses flexographiques)
