As Heat Exchange Media (FOR RTO)
Detailed Product Description
low heat expasion coefficient , large surface area, good heat stability and anticorrosion. it has been produced for 36 years
We provided technology and products to global suppliers of honeycomb ceramic of European and American multinational companies in China. The products are used to purify the gas in RTO, RCO installment, heat transfer and storage in industrial stove. They are used to collect and purify the gas and dust in the filtration and purification installment and they are also used to absorb and transfer as high efficiency packing and carrier in packing tower installment.
