The rich product selection comes from the care of research and development

GRWA focuses on independent technology research and development in three-way catalytic converters, and has successfully reached international standards.

Parts Can be Designed to Meet Your Space and Efficiency Requirements.

Our three-way catalysts are available in a variety of carriers, as well as different standards, including Euro III, Euro Ⅳ and Euro V. The carrier can also be sold separately.

The carrier materials are various and the styles are also various. It can meet the different needs of different customers and increase the customer volume.

When choosing a three-way catalytic converter, what factors do we always consider?

The key to the production of "three-way catalytic converter" lies in the technology of the carrier.

Strain and Environmental conditions on the substrate.

Strain conditions:

Thermal-differential temperature；

Mechanical-packaging,vibration,exhaust;

Coatings.

Environmental:

Thermal loads due to road and traffic conditions;

Ambient temperatures;

Road shocks;

Corrosion.

A high-quality product has very high requirements for the carrier.Good coat-ability;Low thermal mass;Efficient heat transfer from gases;Low pressure drop;High temperature capability;High surface area;High strength;Good thermal shock resistance;Dimensional stability.
