Silicon Carbide Heat Exchanger, PTFE Lined

Glass Lined Equipment Manufacturer

PTFE lined silicon carbide heat exchanger is made of corrosion resistant tube plates and SiC tubes. Due to the utilization of silicon carbide tubes, this silicon carbide shell and tube heat exchanger is a perfect solution adapted to heating, cooling, and condensation of highly corrosive chemicals.

Typical Applications Bromine, Sulfuric Acid, Hydrofluoric Acid, Nitric Acid, Hydrochloric Acid, etc.; Alkalis; Halogenated Compounds; Salt Solutions; Organic Compounds; Technical Data Each tube is subjected to test at pressure of 185 Bar before installation; Shell diameter range: DN100 to DN1000; Standard length of tube: 1000 to 4000mm; Heat exchange area: 1 to 200m2; Tube diameter: 14mm, 19mm; Horizontal or vertical installation; Temperature range: -19°C to 230°C; Pressure range: -0.1MPa to 1.0MPa; CE, ATEX, FDA compliant

Given comprehensive test data and several actual application cases, PTFE lined heat exchanger is the optimal of existing SiC heat exchangers regarding all aspects of reliability, stability, thermal resistance, pressure withstand, and usage range.
