Eisenmann’s regenerative thermal oxidizers feature uncomplicated, robust technology with low operating costs. The space-saving single reactor system treats exhaust air flows from 10,000 to 120,000 Nm³/h, depending on size. For larger air quantities, multiple reactors are deployed in parallel.
Advantages of Eisenmann’s RTOs
The RTO contains a heat exchanger mass consisting of a packing of ceramic honeycomb elements. This is divided into sections – each part alternately serves the cooling phase, while the other serves the heating phase. The exhaust air flows through the RTO’s heat exchanger mass from bottom to top, which heats it up to oxidation temperature – approximately 800 °C. The hot purified gases then flow downwards through the other part of the heat exchanger mass, giving it their heat.
Eisenmann’s patented air distribution system uses a rotating distributor to ensure a steady, alternating flow through the different sections of the heat exchanger in the regenerative thermal oxidizer (RTO). This eliminates the need for complicated valve or damper systems. The air flow remains constant, and there are no volume fluctuations caused by valve switching, as in the conventional three-tower RTO.
