Three-Way Catalytic Converters / Catalytic Mufflers
Designed for natural gas, propane and gasoline fueled spark ignition engines, our Three-Way Catalytic Converters enable equipment operators to comply with a variety of state and federal regulations such as OSHA or RICE NESHAP. Our Three-Way Catalytic Converters are designed for ease of installation and reliable operation. Three-Way Catalytic Converters are available in three basic configurations: clamped on, plain style (welded) or as a replacement purifier muffler.
The major catalytic oxidation reactions which occur are:
FOR OXIDES OF NITROGEN (NOx):
NOx + CO → N2 + CO2
NOx + H2 → H2O + N2
FOR CARBON MONOXIDE:
CO + O2 → CO2
FOR HYDROCARBONS (HC):
H2 + O2 → H2O
HC + O2 → CO2 + H2O
- HIGH EFFICIENCY CATALYTIC COATING
Our Three-Way Catalytic Converters feature a high quality Platinum-Rhodium coating which is very carefully distributed upon a uniform high porosity washcoat. The Platinum-Rhodium precious metal coating and washcoat are evenly dispersed onto a metallic alloy core. The net results are high efficiency non-selective catalytic reactions which lead to very low exhaust emissions. Pollutant conversion efficiencies in excess of 98% can be expected when used in conjunction with recommended air/fuel ratio controllers.
- SUPERIOR THERMAL AND PHYSICAL STRENGTH
Our Three-Way Catalytic Converters are constructed of high temperature tolerant, corrosion resistant stainless steel alloys. Thick stainless steel alloy retainers are used to provide support and stability for the inlet and outlet faces of the metallic core. The effects of high thermal shock and severe vibration are minimized. The larger model catalytic converters (Models 12 SXT and higher) feature inlet flow diverters for even exhaust flow distribution and improved operating efficiency.
- LOW EXHAUST GAS RESTRICTION
Our Three-Way Catalytic Converters feature high strength, ultra-thin metallic core walls which impose a minimal exhaust gas restriction during operation. Even under high load/speed conditions the average engine operating efficiency is barely affected. Under normal circumstances the exhaust gas backpressure restriction will be in the order of 6.0” to 9.0” water gauge (depending on exhaust gas temperature).
- LOW MAINTENANCE AND EASY INSTALLATION
Our Three-Way Catalytic Converters are designed for ease of installation and maintenance with minimal equipment downtime. A large variety of inlet/outlet cone termination configurations (NPT Male/Female pipe, ANSI Flanges, Tube O.D., etc.) are available.
