Glass-Lined Heat Exchangers
Glass-lined heat exchangers are designed for post-reaction heat transfer applications in the chemical and pharmaceutical industries, including condensation reflux, reaction acceleration, and general heat exchange. Available with heat transfer areas from 0.5 to 50 m², design pressure up to 0.6 MPa, and operating temperatures from -20°C to 200°C, they provide a reliable solution for demanding corrosive process conditions.

Designed for highly corrosive media and high-cleanliness process conditions, glass-lined heat exchangers provide a range of corrosion-resistant heat transfer solutions. They help maintain safe media isolation while delivering efficient and stable heating or cooling performance.
Types and Features
- Glass-Lined Disc Condenser
The glass-lined disc condenser is made by lining a round or square plate with a glass layer. A support ring and tie-hole structure are used in the center of the plate for connection. The cavity formed by the glass-lined section carries the corrosive medium, while the central section of the plate carries the cooling or heating medium. Heat transfer is achieved through thermal conduction between the glass surface and the steel plate. - Glass-Lined Cage Heat Exchanger
The glass-lined cage heat exchanger is a tubular heat exchanger that transfers heat through the circulation of steam or chilled brine via two upper inlet and outlet connections. During installation, this structure must be used together with a sleeve stuffing box. The exchanger is inserted into the reactor through a manhole or another large opening, and the inlet and outlet sections are then extended outside the vessel through the nozzle and connected to the sleeve stuffing box. Because the sealing performance at the nozzle connection is relatively weaker, this structure is generally suitable for atmospheric pressure or slight positive pressure applications. - Silicon Carbide Condenser
The silicon carbide condenser uses silicon carbide heat exchange tubes and a fluoropolymer-lined shell, combining corrosion resistance with reliable structural strength and sealing performance. It is one of the more widely used heat exchanger types. Compared with metal heat exchangers, glass-lined heat exchangers, and graphite heat exchangers, it offers higher thermal conductivity, greater strength, and better corrosion resistance. - Built-In Coil
The built-in coil increases the heat transfer area through multiple layers of spiral coils to achieve effective heat transfer. The material for this structure must be selected according to the corrosion characteristics of the process media. It is also only suitable for open-type reactors with a cover.
