An invaluable aid in the effective understanding of heat exchangers. The hot water unit comprises of a tank fitted with electrical immersion heaters. It has a facility to circulate hot and cold water through flow meters. Shell and tube heat exchanger and/or a concentric pipe heat exchanger and/or plate type heat exchanger is provided to conduct the experiment. Other type of heat exchangers can be provided, on request. The system facilitates to study the parallel and counter flow as well.
Flow rates and temperatures can be varied independently and the heat transfer coefficients derived. This system has facility of data acquisition, plotting on-line and historical trends. It carries out complete calculations to determine performance. A comprehensive HELP menu makes the system user friendly
