The most effective method to remove NOx is SRC(Selective Catalytic Reduction), which has been applied to a range of industrial fields
after 1970s. Since US Engel Hard developed SCR catalyst and obtained patent in 1957 firstly in the world,
NOx control catalyst technology has been improved through continuous R&D and applied to gas turbine,
Based on such accumulated technology and field experience, Heesung Engel Hard’s NOx control catalyst is capable of supporting
most suitable catalyst and technology to customers to cope with strict environmental regulation.
 
High NOx activity, low NH3 slip
Low SO2 oxidation and NH3 oxidation
Reduction of catalyst volume by application of many catalyst cells
Maintenance of activity at a broader range of temperature
Low pressure drop by the thin catalyst wall
Easy mounting and separation by catalyst module
High durability
