DESCRIPTION:
Heat exchangers are widely used in various industries. Finned tube Heat Exchanger is a Tube-in-tube type heat exchanger. The inner tube is of Stainless steel with fins on its outside surface. Hot water flows through inner tube and cold fluid flows through the outer tube. The flow rate of hot & cold fluid is measured with the help of rotameters. Inlet and outlet temperatures of fluids are measured with the help of digital temperature indicators. A magnetic drive pump is used to circulate the hot water from a recycled type water tank, which is fitted with heaters and Digital Temperature Controller.
