Glass Lined Shell and Tube Heat Exchanger

Corrosion-resistant tubular condensers for heat transfer processes in chemical and pharmaceutical industries

In chemical and pharmaceutical plants, processes such as boiling, condensation, and heat transfer often involve corrosive or demanding media. Glass lined shell and tube heat exchangers are built to meet these challenges by combining a steel shell, which provides the strength to withstand pressure, with glass-lined tubes that resist corrosion and maintain a smooth, non-reactive surface. The combination of steel and glass lining allows the exchanger to operate consistently while keeping the processed materials clean and unchanged.

Thanks to advanced manufacturing technology originally introduced from Japan, these exchangers achieve heat transfer efficiency several times higher than that of conventional plate exchangers. They also overcome common problems seen in plate-type designs, including slow fluid flow, risk of enamel damage, and limited ability to operate under vacuum conditions. By offering stable performance, high durability, and efficient heat transfer, glass lined shell and tube heat exchangers are widely used in demanding chemical and pharmaceutical applications that require both safety and consistency.

Features
  • Made with glass-lined steel, the multi-tube heat exchanger offers strong protection against corrosion and is built for long service life.
  • The enamel coating, imported from Japan, gives the internal surface excellent anti-stick properties. This keeps residues from adhering, making cleaning and maintenance much simpler.
  • Compared with other glass-lined condensers, the multi-tube design requires less heat exchange area per unit, resulting in a more compact structure and reduced space requirements, while also being cost-efficient.

The tubes are coated using an automatic electrostatic powder spraying process. During production, sensors track the entire coating process in real time, making sure the glass layer is evenly applied, has the right thickness, and contains no pores. This level of control makes sure the coating lasts longer and the equipment runs safely.

Glass lined heat exchangers are available in two main types: plate type and multi-tube type. Plate heat exchangers are compact and easy to maintain, while multi-tube heat exchangers are ideal for handling larger volumes. Both types of heat exchangers can deliver efficient heat transfer and strong resistance to corrosion in chemical and related industries.

Plate models come in two versions: circular plate condensers and square plate condensers. Each design can be selected depending on the space available and the process conditions.

Plate exchangers are modular in design. They are easy to assemble and take apart, and if one plate is damaged, it can be replaced on its own. This not only simplifies maintenance but also helps extend the overall service life of the unit.

Glass lined multi-tube heat exchangers provide much better heat transfer efficiency compared to regular plate exchangers. They also overcome common problems of plate designs, like slower flow rates, risk of enamel cracking, and poor performance under vacuum conditions.
