Regener. thermal oxidiser
Effective VOC destruction
The regenerative thermal oxidizer provides a highly efficient solution to minimize the pollutant emissions of any Volatile Organic Compound (VOC) generated in a productive process. Its high destruction rate (99,5%) assures the fulfilment of the legislation in matter of emissions and its low consumption and automatic operation makes it an investment in environment and power saving.
The system can be adapted with turn-key solutions to any industry that generates VOC and it is specially intended to treat the emissions of the graphic industry like flexo and rotogravure among others.

Auto-therm
Auto-therm and heat regeneration
Heat regeneration is a system based in two highly efficient heat exchangers. These exchangers provide 95% of the required energy to carry out the combustion while the gas only provides the 5% of the remaining energy, unless the system works in auto-therm. The system works in auto-therm when there is a certain concentration of solvent in the polluted air. If the concentration and the calorific power are enough, the system will go into a self-sustainable state, with no gas consumption.

Operation
Heating up, normal and stand-by mode
Heating up: During this phase the fan sends fresh air to the RTO. This air passes through the first tower and enters to the combustion chamber, where it’s heated to 815 ºC. Then, the hot air passes through the second tower where the ceramic blocks absorb the heat of the air before going to the chimney. After a certain time, the air flow switches: the cold air enters through second tower, already hot, and exits through the first one. Every certain time, the airflow switches to keep as much heat as possible inside the system and reduce the gas consumption. When the RTO reaches the working temperature it can start burning the polluted air.
Normal operation: During this phase, the main fan takes air from the collecting system. This air is pre-heated in the first tower and then enters to the combustion chamber. When the air is decontaminated it passes through the second tower where is cooled before going to the chimney. As before, airflow switches every certain time to keep the energy in the system and reduce the gas consumption.
Stand-by mode: When the RTO detects that any pollution source is working, it goes to a stand-by mode, keeping the system at 600 ºC for a certain time. During this time, the RTO is ready to start working immediately. If after a certain time any pollution source starts working, the RTO switches off automatically.
