The Selective Reduction Catalyst is an emission control unit, that uses a chemical reaction to convert harmful nitrogen oxides in exhaust gases into harmless nitrogen and water vapor. This involves injecting a diesel exhaust fluid, into the exhaust stream, where it reacts with nitrogen oxide in the presence of the selective catalytic reduction catalyst, reducing emissions and complying with environmental regulations.Attributes:• Ensures the optimal functioning of the engine.• Contains a catalyst, often made of materials like vanadium, that facilitates the chemical reaction between urea and nitrogen oxides.• Effectively reduces nitrogen oxide emissions, which are a major contributor to air pollution.Applications: The Selective Reduction Catalyst is used in equipment exhaust systems to reduce nitrogen oxide emissions, comply with emission regulations in equipment, promote cleaner exhaust, and environmental sustainability.
