    Yes, The inlet temperature does effect the performance of the catalyst, different constituents convert at different temperatures.. we typically like to see 750-800 F for an NSCR Catalyst, 1250 is considered to be the Maximum temperature

    1. EA Housings / The Round element is a very solid platform for the small Horse power ( < 500 HP) Rich burn engines. this is designed to hold two catalyst elements in a series so that when adding a second element the exhaust gasses pass through the first element and then the second element.. these are typically not used on larger HP because of the large size and weight of the elements the back pressure also increases as you add an element

    2. EL Model Housings.. Linear / lateral Housings.. this housing is a very flexible housing you can configure the housing to hold several elements increasing your single pass cubic FT of catalyst elements typically these are configured for 3 /4/ and 6 elements.. the exhaust gasses make a single pass across the elements and produce a very low backpressure and are intended for the Lean Burn applications but work well on Rich Burn applications requiring > 1 Gm/BHP/HR emissions .. these are also very flexible in their application as if your emission requirements or operating conditions change, you can add or remove elements as desired

    3. ER Model Housings. These are very similar to the EL Housing but the exhaust gasses can pass through 2 catalyst beds rather than just one pass.. these are intended for the rich burn applications greater than 500 HP. these are great in applications where the large HP rich burn emissions requirements are very low typically < 1 GM/BHP/HR

    I hope this helps-

    The Catalyst housings are sized according to the exhaust gas flow rates. the number of elements in a housing is determined by the reduction that is needed, The EL series housing is designed for lean burn applications, and has the elements arranged for a single pass through the elements, the ER series is designed for the Rich Burn applications, and has the elements arranged for a dual pass through the elements. the less reduction that is needed the more blanks can be used, the more blanks that are used the greater the back pressure increase.

    Your cleaning interval is typically determined by your engine condition and fuel gas, and rich burn or lean burn, some engines will produce ash quickly as a few weeks, and others may run a year and still not need cleaning. if you are looking for a maintenance schedule we recommend removing the elements every 6 months of operation blowing them out and turning the elements around, and resealing the doors and elements, then checking your emissions before your annual test and if needed sending them in for a chemical wash.

    complex question, no, just adding tubes will not accomplish Db reduction, the volume of the housing, diameter Vs length of the tube is only a portion of the information needed to determine the reduction of targeted frequency

    it is typically used as required by regulation, larger HP engines may be required to test with an FTIR annually and a lesser instrument may be used for quarterly testing

    AdminKevin Carlin (Tech Advisor, EMIT Technologies, Inc.) commented  · 

    The FTIR is an instrument used in our industry for testing exhaust gas emissions, the instrument is not included in the Catalyst /silencer packaged but rather used for a testing process once the unit is installed it is used to verify the performance of the Engine / Catalyst, there are other options for test instruments, but none as accurate, fast, or portable

    Yes, the different types of catalyst are loaded / designed, specifically for targeted constituents in the exhaust gas, within each of the catalyst families there are different recipes as well, while some may targeted for specific gasses, other may be targeted more towards resisting poisons to help extend the life of the catalyst.

    EMIT does not just offer a "Panel" we offer a very high tech , flexible solution to the outdated existing controls on the ground in the field today, the down turn in the market only provided an opportunity to focus more on research and development to bring some of the best technology to the table, while others hold back on development

    Vertical / horizontal has little or no bearing on the performance of a catalyst, if you are referring to mounting closer to the manifold vs. on top of the cooler, the performance is gained by the additional heat in a lighter loaded application, when the catalyst is mounted close to the manifold, this can work against you in a fully loaded application with too much heat.

    demand drives technology, EMIT does provide an SCR system, there seems to be changes occurring, that SCR is not the final solution, Engine manufacturers are starting to lean back toward the Rich burn market. the cost / demand keeps it on the back burner.

    Computer models indicate that the best flow path is with the element in the downstream location. Field testing indicates that on a rich burn application, lower emissions can be obtained by installing the element in the upstream location

    Can you provide the source of this information,
