Shell & tube Heat exchangers
Glass Shell and Tube heat exchangers can be used for condensation of vapours, vaporisation, cooling and heating of liquids, and have come out to be more advance and beneficial for its following advantages :
- Bigger heat transfer area in one unit.
- Less pressure drop.
- Stuffing box sealing allows easy tube replacement.
The shell and tube heat exchangers are available in various combinations
of Glass/Metal/FRP in shell or headers.
Shell and tube heat exchanger consists of a cylindrical shell which houses a glass tube bundle. Tubes are sealed with shell with the help of PTFE tube sheets. Each tube is individually sealed tube sheets at both the ends. Baffles are provided in the shell to maintain state of turbulence of fluid as well as to hold the tubes.
Shell and tube heat exchanger can be operated within a temperature range of -40°C to 150°C on either side, however, differential temperature should not exceed 120°C at any point. Also, these can be used predominantly under full vacuum, provided differential pressure does not exceed 3 bar g.
The range of overall heat transfer co-efficient in the Shell and tube heat exchangers in most of the applications range between 300 - 900 Kcal/m2,h,°C
These are available in different standard models from 3 M2 to 26 M2
