Product Detail

As a heat exchange media with good crack resistance materials ,Mullite Block are superior in better 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 RTO equipments for Odorous emission treatment.

Mullite block is a ceramic filled heat recovery media that is placed in a formal arrangement, rather than randomly dumped. which can meet and exceed your emissions standards while increasing reliability and profitability in RTOs.
