Silicon carbide block heat exchangers

ace-silicon-carbide-block-heat-exchanger-mersen

CORRESIC® silicon carbide block heat exchangers are adapted to the heating, cooling, evaporation, condensation and absorption of highly corrosive and/or oxidizing chemicals. This design is one of the most versatile type of silicon carbide heat exchangers.

Conception

Rows of holes are drilled through the silicon carbide blocks both horizontally and vertically to form the process and service channels. Heat is transferred by conduction through the silicon carbide left between the rows of holes which separate the mediums being used. SiC block heat exchangers consist in a stack of blocks encapsulated in a steel shell.
