Description
Heat transfer is an integral component in virtually all processes. Depending on the equipment usage requirements, heat exchangers, also called condensers, coolers, and boilers, can perform various functions.
Shell & tube heat exchangers offer large surface area in combination with efficient heat transfer and compactness.
GLOBAL are the pioneers in the field of glass shell and tube heat exchangers in India and their product has a wide market acceptability.
Advantages of Shell and Tube Heat Exchanger Over Conventional Coil Type Heat Exchangers:
- The overall heat transfer coefficient in shell and tube heat exchanger is about 3 times higher than in coil type heat exchanger.
- The pressure drop in shell and tube heat exchanger is minimal compared to 2-3 kg/cm2 in coil side of coil type heat exchanger.
- For requirement of higher heat transfer areas shell and tube heat exchanger is the only alternative.
