Finned tube heat exchanger apparatus

Finned tube heat exchanger apparatus

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. For hot water, a recirculation type water tank is provided, fitted with heaters and Digital temperature controller. Cold water at constant head condition is to be provided from laboratory overhead tank by the end user. Direction of cold fluid flow can be changed from parallel or counter to hot water so that unit can be operated as parallel or counter flow heat exchanger. Flow rates of hot and cold water are measured using Rotameters. A magnetic drive pump is used to circulate the hot water from the recirculation type water tank. Digital temperature indicator with multichannel switch is fitted in control panel to observe the temperature of hot and cold fluids at inlet and outlet of heat exchanger.
