Heat Exchangers, Durability : Long Life

• Coil Type Glass Heat Exchanger
• Glass Boiler
• Glass Immersion Heat Exchanger
• Product Cooler
• Hose Connector
• Shell And Tube Type Glass Heat Exchanger

There are two types of glass heat exchangers, coil type and shell and tube type.

The overall heat transfer co-efficient of borosilicate glass equipment compare favourably with many alternative process plant construction materials. This is because the smooth surfaces of the glass improve the film coefficient and reduce the tendency for fouling.
Two basic types of glass heat exchanger are described in this chapter, Coil type and Shell and Tube type. Shell and tube type heat exchangers are available with glass or Mild Steel (MS) Shells in combination with glass tube as standard. The shell, end bonnets can be supplied in other material of construction eg, CS, SS, PTFE lined, FRP, glass lined etc, depending on the process condition. The tube can also be supplied in Silicon Carbide. 
Shell & Tube Heat Exchanger consists of a cylindrical shell which uses a glass tube bundle. Tubes are fixed in the tube sheet. Each tube is individually sealed by PTFE 'O' ring in the tube sheet at both ends. 
Following are the advantage of using Shell & Tube heat exchangers : 
• Larger Heat Transfer Area in single unit
• Low pressure drop
• Easy Tube Replacement.
• Tube can be Plugged in case of Breakage.
Glass coil type heat exchangers are available as condensers, boilers or immersion type units with heat transfer areas up to 8m2. There are no internal sealing problems as the coil is welded to the shell making a one piece unit.
