Catalyst Technology - Principles of Operation

The principle of operation for both the explosion-proof and high performance pads is the same. The catalyst pad rests on a low watt density electrical element. Required only during start-up, the element raises the temperature of the catalyst bed to the activity temperature of 120°C (250°F). Once this temperature is achieved fuel enters the back of the heater and is dispersed through the insulation and catalyst pad. The combination of fuel, oxygen, and pre-heated catalyst initiates a chemical reaction resulting in the creation of infrared energy. After oxidation begins, the self sustaining catalytic reaction continues, until either the fuel or oxygen supply is interrupted. The by-products of this flameless combustion are carbon dioxide, water vapor, and infrared heat.
