RTO ceramic honeycomb

Item Code: Features:
  • Description

Ceramic Honeycomb materials are mainly as the support of catalyst, heat exchange media and filtrate substrate. The cordierite honeycomb ceramic, which has a low thermal expansion coefficient, good thermal stability and thermal shock resistance, low back pressure, is widely used as catalytic carrier, especially for auto exhaust purifier. It becomes the first choice for the manufacturers of the purifier.

*As support of catalyst, ceramic honeycomb materials are typically used for purifying automotive emission, removing bad smell etc, for instance, utilized in exhaust catalytic converter, air-fresher machine for hotel, restaurant, toilet and so on.

*As heat exchange media, ceramic honeycomb materials are mainly utilized in heat recovery unit of RTO s instead of ceramic saddles.

*As filtrate substrate, ceramic honeycomb materials are generally utilized in food processing, environmental industry, metallurgical industry etc. for filtering particulate in industrial waste gas and bubble in liquid of molten melt and making the molten melt laminar so as to increase casting yields, also filtering impurities in juice, dextrose and sucrose etc.
