Wide-Gap Welded Plate Heat Exchanger for Alumina Decomposition Applications

Engineering Pain Points

Efficient heat transfer is significantly compromised when processing media with high viscosity, solid particles, fibers, or a tendency to crystallize. Traditional plate heat exchangers frequently clog because of narrow flow channels and therefore require frequent maintenance. Shell-and-tube exchangers are resistant to clogging, but they have low heat transfer efficiency, excessive footprint, and cumbersome cleaning procedures.

To address these inherent hydraulic and thermal limitations, Shanghai Heat Transfer Equipment Co., Ltd. developed the Wide-Gap Welded Plate Heat Exchanger. After more than 20 years of optimization, this solution is now widely used in metallurgy, ethanol, chemical processing, and other industries.

Core Technical Advantages

High structural reliability: The unit uses a fully automated welding process to form a gasket-free, integral welded plate bundle, completely eliminating leakage risks caused by gasket aging or corrosion. Compared with traditional gasket-sealed equipment, this structure can withstand higher operating pressure and temperature, effectively avoiding channel deformation or medium leakage caused by pressure fluctuation or sudden temperature change, and significantly improving long-term operating stability.
