CADAIR provides high quality thermal regenerative catalytic combustion furnaces, especially for low concentrations of hazardous air pollutants (HAP) and volatile organic compounds (VOCs), and is an upgraded version of RTO.

There are three or more heat regenerative chambers at the front of the oxidation chamber, and the regenerative ceramics filled in them constantly repeat the cycle action of heat absorption and heat release when working to achieve the recovery of heat released during the oxidation of polluted gases.Through full optimization of the design, the efficiency of heat recovery is often more than 95%, which makes the energy consumption required to maintain the combustion temperature is greatly reduced.

In the middle of the thermal storage layer, there are 2 to 3 layers of catalysts, which can greatly reduce the temperature conditions required for combustion, that is, most of the VOCs can start to burn at 260 to 300 ° C. Combined with its ultra-high heat recovery efficiency, even if the exhaust gas concentration is less than 1,000mg/Nm³, the heat recharge of the equipment is almost zero during operation, which is a very efficient and energy-saving device.

It should also be noted that when the polluted gas contains heavy metals (such as lead), toxic elements (such as sulfur, phosphorus, arsenic), and halides (such as chlorine, bromine, fluorine), these components will be preferentially captured by the catalyst layer and combined to form an indecomposable combination, resulting in a gradual reduction of the effective catalyst content and eventually the loss of catalytic activity.
