Three way Catalysts

EnviCat® TWC

Three way catalysts (TWC) are used to simultaneously remove CO, HC and NOx from exhausts of spark ignited engines. The catalysts are designed to oxidize the CO and HC to harmless carbon dioxide and water and reduce the NOx to Nitrogen at the same time.

Sud Chemie offers a broad range of Catalytic converters for mobile & stationary engines fuelled by Gasoline, LPG & CNG. The use of high thermally durable wash coats and an automated state-of-the-art coating technology ensures long life of the catalyst. The superior thermal stability of the wash coat and use of improved oxygen storage materials permits the catalyst to be mounted closer to the engine for better cold start activity.

The Quality of the catalysts are approved by the certifying agencies and are used by major OEM’s in India and abroad. The catalysts are designed to comply with the global legislated standards.

Catalytic converters are available on both Ceramic or Metallic honeycomb substrates, including structured substrates and also on other substrates (e.g. foams, wire mesh etc), which can be provided as per request.

TWC EnviCat® can be custom designed to meet preset performance parameters for:

  • Compliance with legislated emission norms
  • Thermal and Mechanical Durability
  • Poison resistance
