ISO Certified Honeycomb Ceramic for Heater Gas Accumulator

Product Description

Corundum-based Honeycomb Ceramic Heat Accumulation Substance
It's features of corrosion resistances, large specific surface area, small heat
Resistance, good thermal conductivity and excellent thermal-shock resistance, fast heat exchanging and energy saving. It's widely used in many fields.
The honeycomb ceramic as the heat exchange media is the key part for heat storing HTAC
( High Temperature Air Combustion) technology. It is the best choice for RTO, heat exchanger
And other environmental protection and energy saving products.

Characterics:
*Low thermal expansion
*Large specific heat capacity
*High specific surface area
*Low pressure drop
*Small thermal resistance
*Good thermal conductivity
*Good Heat-shock resistting ability

Application: Iron and steel, metallurgy, petrochemical, electric power, boiler and Fuel elecric plant, Thermal power plant, theheat power station etc
