Exhaust Gas Purification Catalysts (Oxidation-, Deodorization-, VOC-, and Combustion Catalysts)

Metal Honeycomb Catalyst

Features

• Has a large surface area and high catalytic reactivity due to the use of a honeycomb structure
• High opening ratio and low pressure loss due to thin wall thickness of honeycomb structure
• Compared to ceramic honeycombs, they have more freedom in size and can be square, round, or larger.
• Higher strength than ceramic honeycombs and easier to handle, as it is a metal honeycomb

Shape

Size (example)

Various sizes from small to large are available, mainly in square and round shapes.
