Ecopure® RCO - Regenerative catalytic systems
If exhaust air from a production facility has a very low VOC concentration, a more efficient heat exchanger material has to be applied than the recuperative heat exchanger systems used in the Ecopure® LPX model. Dürr's Ecopure® RCO (regenerative catalytic oxidizer) is the right system for this purpose. In this system, the process air is heated up in a regenerative manner via ceramic heat exchange media before the VOCs are then converted by the catalyst. After treatment, the heat in the purified air is again recovered in the ceramic media. The stored heat is then transferred to the contaminated air again. To ensure that this principle works reliably, the Ecopure® RCO has at least two ceramic heat exchange media beds that are interconnected by a combustion chamber, which alternately transfer and/or absorb the energy.
