China Ceramic Honeycomb as Heat Transfer Media for Rto

Ceramic Honeycomb as Heat Transfer Media for RTO

Regenerative thermal/catalytic Oxidizer(RTO/RCO)are used to destroy hazardous air pollutats(HAPs), Volatile organic compounds(VOCs)and odorous emmissions etc, which are extensively applied in the fields of automotive paint,Chemical industry, electronic&electric manufacturing industry,contact combustion system and so on .

ceramic honeycomb is specified as structured regenerative media of RTO/RCO.

Advantage:

Variety of materials& specifications
Big specific surface area
small resistance loss
Low thermal expansion coefficient
High water absorb rate
Outstanding crack-resistance
