Product Description

Ceramic heat exchangers

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
*  Outstanding crack-resistance
