HEAT EXCHANGER TRAINING
APPARATUSMODEL: HE 158C
SOLTEQ Equipment for Engineering Education & Research
THIS Heat Exchanger Training Apparatus (Model: HE 158C) is a
bench type unit designed to allow
students to get familiarised with different kinds of heat
exchangers and to collect the necessary experimental
data for the calculation of heat loss, heat transfer
coefficient, log mean temperature difference, etc. Studentwill also
be able to study the effect of flow rate on the heat transfer rate.
Later, students may use this knowledge for
designing complex industrial heat exchangers.
The HE 158C is supplied with four types of heat
exchangers with two 50-L stainless steel sump tanks
as the source for the hot and cold water circuit. The hot
tank is fitted with a 11.5 kW immersion type heater which
is protected against possible over heating. Each tank
has a centrifugal pump to deliver the hot and cold water
to the heat exchangers. The pumps are somehow
protected from dry-run by level switch installed in each
of the sump tanks. A temperature sensor and
temperature controller are also provided to maintain a
constant desired temperature inside the hot water tank.
The unit is supplied with all necessary instruments to
measure the inlet and outlet temperatures of the hot
and cold water as well as the flow rates of the hot and
cold water and the pressure drops across the heat
exchangers. Piping and fittings are made of stainless
steel materials to prevent rust. The hot water and cold
water circuits are properly insulated to minimize heat
losses or heat gains between the tank and the heat
exchangers.
