Fluid is passed through the shell (cylinder) and various tubes (heat transmission tubes), and heat exchanged between them.
Shell and tube type heat exchangers (multi-tubular heat exchangers) feature a shell (body) and multiple tubes (heat transfer tubes).
They are designed so as to achieve a large transfer surface area within a small space, with minimal loss of fluid pressure. They can be applied to all purposes, from low temperature to high temperature, from low pressure to high pressure, and for heating, cooling, evaporation and condensation.
They are highly reliable in comparison with other types of heat exchanger, and are the most widely used in the hydraulic and chemical related industries.
Their basic structure is simple, so maintenance is very easy.
