Johnson Matthey's ModulexTM and DualOx® catalytic converters for stationary engines were developed to satisfy the increasing demand for clean air technology combined with silencing.

Johnson Matthey's innovative and economical ModulexTM and DualOx® catalytic converters are designed to accommodate oxidation catalysts and three-way catalyst elements to reduce exhaust emissions and noise, when used in combination with a silencer. The ModulexTM and DualOx® catalytic converters are utilized to achieve clean air emissions limits in many engine applications, including gas compression, gas transmission, power generation, irrigation and pumping, and standby equipment. The ModulexTM and DualOx® catalytic converters can be installed on rich-burn or lean-burn stationary gas engines or on stationary diesel engines and are pre-engineered for a wide range of engine sizes. The flexibility of the modular designs allows the use of different flange sizes and the addition of a silencer.

The ModulexTM and DualOx catalytic converters converters can be equipped with Johnson Matthey's HAPGuard Monitor. The HAPGuard was designed for use with catalytic converters equipped with oxidation catalysts and three-way catalysts to help engine operators remain in compliance with RICE NESHAP.
