Product Detail

Ceramic honeycombs have proven their value as the most efficient heat storage media for regenerative use.

As a heat exchange media / re-circulation heat exchangers , Mullite material honeycombs are widely used for his high-performance of thermal shock resistance , higher AL content and lower coefficient of heat expansion comparing with alumina and dense alumina material, which has been widely used in heat recovery systems in RTO equipments among industrial fields.
