GLASS SHELL & TUBE HEAT

EXCHANGER STUDIES UNIT

SOLTEQ®

MODEL: HE 667

This Glass Shell & Tube Heat Exchanger Studies Unit (Model: HE 667) is specially design as a standalone

mobile unit for heat exchanger studies. One of the most important processes in engineering is heat

exchange between flowing fluids. In heat exchanger the temperature of each fluids changes as it passes

through the exchanger, and hence the temperature of the dividing wall between the fluids also changes along the

length of the exchanger. Examples in practice in which following the fluids exchange heat are intercoolers andpreheaters, condensers and boilers in steam plant, condensers and evaporators in refrigeration unit and many other

industrial processes in which liquid or gas is required to be either cooled or heated.

DESCRIPTION

The unit consist of an exchanger with cold and hot water

circulation systems. Instrumentations for heat

exchanger studies are installed to collect flow, pressure

and temperature data, plot graphs, calculate heat

transfer coefficient, heat exchanger efficiencies, log

mean temperature difference and etc.

Tabulated results and graphs can be plotted.

Hot water circulation line is insulated for safety

purpose and to minimize heat loss.
