Catalyst silencer

MIRATECH® RX Series™ housing is a high-value catalyst-silencer combo unit for engines in the 200 to 8,000 hp range. The standard silencer housing is constructed with a double wall carbon steel shell and is coated with high temperature black paint.

The optional stainless steel housing is constructed with a double wall stainless steel shell but is not painted. The housing includes lifting lugs, four (4) – 1/2″ NPT couplings located in the inlet and outlet sections and on before and after the catalyst element, two (2) – 18mm oxygen sensor couplings located in the inlet and outlet flange neck, and one (1) ½” NPT drain below the outlet. The housing also includes a flow diffuser, which is constructed of 304 stainless steel. The RX Series™ catalyst silencer combo housing units are designed for use with open foil or NEXT® elements.

Access to the catalyst is provided through a simple cover plate design, thus eliminating the need to remove the housing from the exhaust piping to service the catalyst. The convenient location of the ½” NPT ports and 18 mm ports allows for easy installation of pressure gauges, thermocouples, sample tubes, and oxygen sensors to monitor catalyst performance or connect to an adaptive AFRC (air fuel ratio controller). The benefits to operators are simple and quick installation, maintenance, and performance monitoring, all of which save time and money.
