    • Corrosion Resistant Silicon Carbide Heat Exchanger

    This silicon carbide heat exchanger composes of corrosion-resistant plates and silicon carbide tubes, fit for corrosive processing. The heating of the shell and tube silicon carbide heat exchanger is realized by the heat exchange tube made from corrosion-resistant silicon carbide, which is the first choice as a medium for cooling and condensing chemical corrosive process.
