Advantages of Shell and Tube Heat Exchanger Over Conventional Coil Type Heat Exchangers :
- The shell and tube heat exchanger offers an overall heat transfer coefficient nearly three 3 higher than a coil-type heat exchanger, ensuring efficient thermal exchange.
- With a minimal pressure drop, the shell and tube heat exchanger outperforms coil-type heat exchangers, where the coil side experiences a pressure drop of 2-3 kg/cm².
- For large-scale heat transfer applications, the shell and tube heat exchanger is the best solution, providing a high heat transfer area to meet industrial demands.
Construction Features of Shell and Tube Heat Exchanger :
The Shell and Tube Heat Exchanger from Goel Impex is designed for efficient heat transfer, featuring high-quality glass tubes individually sealed into a PTFE tube sheet using specialized PTFE sockets and packing. This advanced ferrule-type sealing allows for easy tube replacement and hassle-free cleaning, ensuring long-term performance.
Additionally, strategically placed baffles on the shell side improved heat transfer efficiency by increasing turbulence. For a detailed view of the construction, refer to the provided diagram.
- The Made from SCHOTT DURAN.
- Joint less tubes offer better pressure rating.
