Description
Tesca Plate Heat Exchanger Trainer is 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. 
The shell and tube heat exchanger consists of parallel tubes fitted in a shell containing baffles along its length.  The whole unit is insulated. The baffles ensure turbulent water conditions thus provide good heat transfer.  Flow rates and temperatures can be varied independently and the heat transfer coefficients derived. 

List of Experiments
To study and compare the heat exchanged in shell and tube type and concentric type heat exchanger.* 
Determination of mean temperature difference under parallel and counter flow 
Determination of overall heat transfer coefficient. 
To determine the heat exchanger capacity. 
* Only if more than one heat exchanger is ordered.
