Propane is a common fuel used in many types of settings. Many forklifts operate using propane as the fuel of choice rather than diesel or gasoline. Propane is also sometimes used in factory settings for machine operation or as a way to prepare meals in some outdoor eateries. While propane is efficient, it also has the ability to create fumes similar to those generated when gasoline or diesel is used. The result is that it pays to invest in exhaust purifiers that will boost the performance level of the emissions system and reduce the buildup of residue within the system.

Propane exhaust purifiers are additional equipment that an be added to most types of exhaust systems. This is particularly important when the engine is being used in a closed setting. For example, a fork lift powered by propane may be used to transport raw or finished goods around a plant floor. When the exhaust system is not efficiently removing hydrocarbons or converting carbon monoxide to carbon dioxide, the result is fumes that can cause headaches and much worse. Along with being unhealthy for the lift driver and others who come in contact with the fumes, the combination of toxic gases is harmful for the environment. Choosing to invest in an efficient purifier will correct the problem.

Along with being kind to the environment and maintaining a healthier work setting, the right type of propane exhaust purifier also protects the entire catalytic exhaust system. By helping to remove or transform the impurities, there is less opportunity for blockage. That means the system components are subjected to less wear. You will find that the equipment needs repairs less often, maintenance is simpler, and you can expect to get more years of reliable use from those engines.

Add on units of this type come in several designs and sizes and are designed to comply with the standards set by the major regulatory agencies in North America. Along with improving fuel efficiency and creating a safer working environment, the purifier will make it easier for you to remain in full compliance and avoid costly fees and penalties.

If there are any questions about what design for the propane purifier is needed, a professional can aid in the selection. By taking into account factors like the engine size and design along with the part numbers for the muffler and converter, it will be simple to determine if a universal purifier will work or if producing a custom unit is necessary.

A propane engine does not burn “clean” emissions. Many of the emissions from a propane engine are the same as any other gas engine. Primary pollutants include carbon monoxide (CO), hydrocarbons (HC) and aldehydes (HCHO). The propane exhaust purifier is an add-on unit placed within the current exhaust system eliminating nearly all engine downtime. Propane exhaust purifiers enable equipment operators to comply with a large variety of state and federal regulations such as with CARB, CAL OSHA, EPA, OSHA or RICE NESHAP. Designed for ease of installation and reliable operation, the purifiers are available in three basic configurations: clamp-on, plain style (welded) or as a replacement purifier muffler.

  1. Purifier Muffler:
    The purifier muffler is a "direct fit" replacement for your stock original equipment muffler. To install a purifier muffler remove the stock original equipment muffler and install the catalytic muffler directly in place. We will require your equipment make, model, machine serial number and the stock muffler part number when you place a purchase order. For additional information click here.


  2. Clamp-On Purifier Scrubber (SXT-P):
    The SXT-P (plain) purifier scrubber is designed to be installed inline in the engine exhaust system before or after the original equipment muffler. Normally we recommend that you install the model SXT-P purifier scrubber as close to the engine exhaust manifold outlet or turbocharger outlet as possible. The diesel exhaust purifier scrubber requires exhaust heat energy to function properly therefore the closer you are to the engine exhaust manifold outlet or turbocharger outlet the better the diesel exhaust purifier scrubber will perform. We will require your exhaust pipe outside diameter (O.D.) when you place a purchase order.

The Major Catalytic Oxidation Reactions which Occur are:

Propane Exhaust Purifier
Carbon Monoxide (CO):
CO + O2 CO2

Hydrocarbons (HC):
H2 + O2 H2O
HC + O2 CO2 + H2O


    Our 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 catalytic reactions which lead to very low exhaust emissions. Pollutant conversion efficiencies in excess of 90%+ can be expected when used in conjunction with recommended air/fuel ratio controllers.


    Our 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. Larger catalytic converters models (Models 12 SXT and higher) feature inlet flow diverters for even exhaust flow distribution and improved operating efficiency.


    Our 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).


    Our 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.
