SCR DeNOx catalyst DNX-series


The DNX-LD catalyst is a fiber reinforced Vanadium-Tungsten-Titania catalyst. The catalyst is available in a version with a 0.3 - 0.4 mm wall.

Application areas:

The DNX-LD catalyst is suitable for operation in a medium-dust environments and is typically used in SCR installations within boiler applications.

Features and Values:

The DNX-LD catalyst can be optimized to meet the specific operating condition by varying the activity of the catalyst, the pitch sizes and the wall thickness to give the desired performance.

Our industrial experience together with the extensive testing in our laboratories have proven the DNX-LD catalyst activity is maintained over long operation in a wide range of applications.

The exceptional combination of the above features of the DNX-LD catalyst ensures a long trouble-free service life. This translates directly into minimized catalyst and operating costs and thus it ensures excellent value and easy operation. The long service life combined with the low pressure drop makes the DNX-LD catalyst very economical to operate.
