Choose the best catalytic combustor on the market. Condar combustors are made with high-quality materials in our North Carolina factory. Approved by the EPA. For DutchWest wood stoves. Ceramic honeycomb coated with platinum and palladium, elements engineered to maximize catalytic reaction. Features a durable honeycomb that won’t crack or crumble, even at highest operating temperatures. Strategically placed in the smoke path inside a wood stove, catalytic combustor causes smoke to burn as fuel, creating more heat from less wood. That means a wood stove can be burned slowly, transforming most energy stored in a log to the room as heat, instead of to the outside as air pollution. Steel upgrade available (ASIN B00181FEQ0). A worthwhile extra expenditure for better performance. Condar recommends replacing your stove’s catalytic probe thermometer each time the combustor is replaced. Choose 2.5-inch catalytic probe thermometer (ASIN B00113L8QU), 1-inch catalytic probe thermometer (ASIN B00113J7RM), or Watchman Electronic Catalyst Monitors (ASIN B01CUV3UK8 or B01672BO7W).
