SiC Heat Exchanger

This standard type silicon carbide heat exchanger is a shell and tube heat exchanger made with corrosion-resistant tube plates and silicon carbide (SiC) tubes, making it an ideal solution for various applications such as heating, cooling and condensation processes involving highly corrosive chemicals. With its advanced material and robust construction, our SiC shell and tube heat exchanger can provide optimal corrosion resistance performance and long service life for the chemical and pharmaceutical industries.

Typical Applications

Bromine, Sulfuric Acid, Hydrofluoric Acid, Nitric Acid, Hydrochloric Acid, etc.;

Alkalis;

Halogenated Compounds;

Salt Solutions;

Organic Compounds;

Comparison Chart of Thermal Conductivity

We can use double-tube plates design to separate process fluid from working fluid so that the two fluids will not be mingled even the O-ring breaks.
