Regenerative Thermal/Catalytic Oxidizer (RTO/RCO) are used to destroy Hazardous Air Pollutants (HAPs), Volatile Organic Compounds (VOCs) and odorous emissions 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
