Selective Catalytic Reduction (SCR)

Selective Catalytic Reduction (SCR) is a post-flue gas treatment that is capable of reducing NOx emissions from a wide variety of boiler systems. SCR is one of the most effective ways of reducing NOx in a flue gas stream, with reductions up to 95%.

Industry’s only totally integrated system
Reduces NOx by up to 95%, down to 1 ppm
Ammonia reacts with NOx to form harmless nitrogen and water
CFD modeling used to optimize every system
Works with Firetube, IWT, HRSG, and retrofit boilers

The (CM) designation in our part identification number represents our Model CS with an accessory collar (spot welded) added to one end (male end) of the flange that provides an installer-friendly connection for our customers, especially with larger diameter sizes.

MW – Special Gas Venting

Model MW is a viable competitive option. Our single wall product is limited in use and not to be installed in a fully enclosed combustible enclosure. Model MW can only be enclosed on two sides with combustible materials. Do not wrap the MW vent system or place any type of insulation in the required clearance space in an effort to reduce the required clearance or as an attempt to create a fire protective enclosure. Clearance to non-combustibles is as required for installation, access, inspection, or per local code

Van-Packer’s Model MW special gas vent is listed by UL file MH45778 as a “Special Gas Vent” in the United States.
4″ I.D. to 10″ I.D. available in 1″ increments and from 10″ I.D. to 48″ I.D. available in 2″ increments.

The MW special gas vents have a maximum operating temperature of 550° F (288° C) and may be used with negative, neutral, and positive vent pressures (40″ water column maximum positive pressure).
