Silicon Carbide Heat Exchanger, PTFE Lined
SiC Heat Exchanger
Our PTFE lined silicon carbide heat exchanger is a shell & tube heat exchanger with PTFE lining. The heat exchanger is made of corrosion-resistant tube plates and silicon carbide (SiC) tubes, with the capability to handle highly corrosive chemicals in various heating, cooling, and condensation applications for chemical and pharmaceutical industries. Thanks to the usage of PTFE lining that can resist many corrosive chemicals under extreme operating conditions, this shell & tube heat exchanger is the perfect option for the chemical and pharmaceutical industries, delivering long-term reliability and guaranteed longevity.
