Exhaust air treatment RTO/2P – Regenerative thermal oxidation with integrated regenerative heat exchanger system and puff capture.
Economic, compact 2-chamber system for low solvent laden. The system consists of 2 thermally-separated regenerator chambers. Switching individual chambers between solvent laden and clean air is performed by two poppet valves.
When switching from solvent laden to clean air the exhaust air is briefly fed into capture tank. This is to ensure that after switching no concentration peaks appear in the clean exhaust air.
After switching the capture tank is flushed out via a duct connected to the inlet side.

They are covered with a ceramic insulation layer. Above the regenerator chambers is a central combustion chamber that is also covered with a ceramic insulation layer. This also contains the support/booster burner system.
In addition, the internal pipework (solvent laden collector and clean air collector) and the required fans always belong to the system.
The regenerative, purely thermal exhaust air treatment system can be operated from small VOC concentrations of approx. 1.5 g/Nm3autothermally. That means no further primary energy additive (oil, gas) is required for safe oxidation of toxins.
The system can be used as safe and flexible solution for oxidation of all organic exhaust airflows. Even the constantly tightening legal provisions for pure air values are safely respected.
Hydrocarbons are oxidised to carbon dioxide and water in a temperature range of approx. 800 – 840°C.
The oxidation energy released is used for pre-warming process exhaust gases. Concurrently the residual oxidation energy can be fed back into the process. This can be performed either direct via a hot gas outlet or indirect via an air-to-air heat exchanger.
The systems are completely process-controlled and require minimal servicing.
