What is the recommended temperature range for exhaust being supplied to a TWC?
TWCs manufactured by CleanAIR Systems begin operating efficiently with exhaust temperatures as low as 650 degrees F. Insulation of the exhaust system may be considered to minimize heat loss if the TWC is not placed directly after the engine exhaust outlet, making it difficult to reach a minimum operating temperature. Some natural gas (NG) engines can have exhaust temperatures exceeding 1200 degrees F. These higher temperatures can result in the deterioration of the catalyst materials and supporting substrates. Consult with CleanAIR Systems for additional options when considering a TWC for use with engine temperatures exceeding 1200 degrees F.
