HEAT EXCHANGER SERVICE MODULE

The Service Module (TD360) is the core of the TD360
range. It provides hot and cold water to the heat
exchangers and all the instruments needed to measure
their performance. All fluid connections to the optional
heat exchangers are self-sealing quick connectors ? for
safety and simplicity. The hot and cold fluid streams have
different connectors to reduce errors.
The services module?s hot water system includes a tank
with a PID controlled electric heater, a pump and tank
level indicators. An electrically operated valve opens to let
water in to fill the tank. The tank has protection in case of
over temperature, low water level and overfilling. The hot
water system gives stable flow rates and temperatures.
The services module?s cold water circuit has a flow regulator
and connection for an external mains water supply.
Both the cold and hot water system have precision needle
valves and turbine flow meters to control and measure the
flow rates.
Thermocouples at the connectors measure hot and cold
inlet and outlet fluid stream temperatures. Some heatexchangers
also have built-in thermocouples for extra
temperature measurements. Clear, multiline digital displays
show the temperatures and flow rates of the fluid streams.
All optional heat exchangers have the same nominal heat
transfer area and wall thickness, so students can compare
them directly.
You can do tests with or without a computer connected.
However, for quicker tests with easier recording of results,
TecQuipment can supply the optional Versatile Data
Acquisition System (VDAS?). This gives accurate real-time
data capture, monitoring and display, calculation and
charting of all the important readings on a computer.
