Honeycomb Ceramic Regenerator,Ceramic Heat Exchanger
?
?
Honeycomb ceramic is new developed ceramic part.
Because of it's features of corrosion resistances, large specific?surface?area, small heat resistance, good?thermal conductivity?and excellent thermal-shock?resistance,?fast heat exchanging?and energy saving. It's widely used in many fields.
The honeycomb ceramic as the heat exchange media is the key part for heat storing HTAC ( High Temperature Air Combustion) technology. It?is?the?best?choice?for?RTO,? heat?exchanger and?other?environmental?protection?and?energy?saving?products.

Honeycomb Material:
We can make honeycomb ceramic various material. Like alumina, multiple cordierite etc.
