How does SCR work? Selective Catalytic Reduction. SCR systems use our catalytic design to react ammonia injected into the air stream with the NOx present. This approach requires an operating temperature of 320-700 º F (160-320 º C) depending on the catalyst used. For flue gas that is already in this range, the SCR system will be a good choice. Systems use about .4 wt. NH3/wt. NOx . Because there are so many variables, please contact us for specific information. Contact us for more details on any... (read more)

NOxiTHERM SCR System SCR – or Selective Catalytic Reduction (of NOx) – is a very similar process to SNCR except that a catalyst is used to accelerate the “redox ” reactions which, compared to SNCR, typically require less reductant and occur at lower temperatures (190-450 °C). NOx reductions of up to 95% are routinely achieved in the field with little, or no, reductant slippage. Even higher NOx control is possible via the use of multi-staged SCR systems. SCR catalysts are typically made... (read more)Browse Selective Catalytic Reduction (SCR) Systems Datasheets for LTB America, LLC
Catalyst / Purifier / SCR Insulation Firwin manufactures removable insulation blankets for purifiers, catalysts, and SCRs. Proper insulation is an important component of optimal catalyst performance. Effective heat containment speeds up the time for the Catalyst to reach the minimum effective temperature for effective pollutant burn off. Insulation blankets on Purifiers and Catalytic converters contain heat flow from the housing which: • Brings the catalyst up to its effective operating temperature much faster,. •... (read more)
Branch Environmental Corp.
Selective Catalytic Reduction (SCR) System Branch Environmental Corp. provides selective catalytic reduction (SCR) systems for a broad variety of applications, including flue gas systems and chemical process applications. SCR systems use either ammonia or urea, which is injected into the gas and reacts with N0x on the catalyst surface to destroy the N0x - resulting in nitrogen and water vapor. (read more)
Trigger Guards and Deadmans handles proportion of stock components both design times and engineering charges are kept to a minimum. Examples of just some of the many varieties of trigger guards and deadman's handles that we have produced over the years are shown above. Of course, not all custom-built hand controllers will be able to take advantage of modular range components. Inevitably such products require more engineering input, and delivery times tend to be longer, but they are still reasonable and overall costs remain surprisingly... (read more)

Trackball Designs Daco trackballs in particular have the added benefits of being extremely robust whilst providing an exceptionally smooth, free, linear action. These characteristics are the results of a design aimed at producing a "professional" quality device. In many trackballs the shafts of the encoders used to sense rotation are also used as two of the three supports for the ball. This design brings benefits in terms of cost and size but, inevitably, trackballs using it have some shortcomings... (read more)
