How Catalysts Work

How does a Catalyst Work?

A woodstove catalyst isn't a filter. Instead of physically capturing particles, the combustor deploys chemical catalysis to break apart the molecular structures of unburned particles. Platinum and/or palladium atoms loaded in the honeycomb cells trigger the chemical reaction. Your catalyst converts smoke into water vapor, carbon dioxide, and HEAT.
Catalysis is used in other catalytic converters, such as automobiles, but woodstoves are virtually unique in benefiting from the HEAT that takes place from the catalytic reaction. Your Condar catalyst is engineered to maximize HEAT. Emissions from the chimney become invisible carbon dioxide and white water vapor. Chimney emissions from inferior or worn-out catalysts are dark.

What does light-off temperature mean?

Chemical catalysis doesn't take place at room temperature, or any temperature lower than light-off temperature. That's the reason for your stove bypass, diverting around the catalyst, during warm-up.

For ceramic-honeycomb catalysts light-off occurs when your woodstove reaches about 500° Fahrenheit (260° Celsius),

For Condar steel-honeycomb catalysts, light-off temperature is reached faster, at approximately 400° Fahrenheit (204° Celsius).

Use a woodstove thermometer or digital catalytic thermometer to monitor temperature of the catalyst, to achieve maximum catalytic reaction during your burn.

Catalytic reaction maxes out at about 1300 degrees Fahrenheit through any combustor. Exceeding this temperature is destructive to the combustor and to the components of your stove.

What Our Customers Are Saying:

"My woodstove is ten years old, so I was surprised to find that Condar Company not only offered a catalyst for my stove; they actually had it in stock and at half the cost of the original! I can already confirm the installation and fit is perfect. I'm confident the catalyst will perform as well or better than the original, and I'm recommending Condar to every woodstove owner I know." -Dan James; Hamilton, Michigan
