A bench-top base unit for examining and comparing small-scale heat exchangers to help students understand how they work. Requires at least one of the four associated experiments.
Key features
• A bench-top service module with optional small-scale demonstration heat exchangers – designed for teaching
• Optional heat exchangers include the most common types used in industry (tubular, plate, shell and tube, and a jacketed vessel with coil and stirrer)
• Simple and safe to use – foolproof fi ttings allow students to change and connect the optional heat exchangers quickly and easily – needs no tools
• Clear digital displays of all readings – you do not need a computer to work it or take readings
• Can connect to TecQuipment’s Versatile Data Acquisition System (VDAS®)
Description
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 fl uid connections to the optional heat exchangers are self-sealing quick connectors – for safety and simplicity. The hot and cold fl uid streams have diff erent 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 fi ll the tank. The tank has protection in case of over temperature, low water level and overfi lling. The hot water system gives stable fl ow rates and temperatures.
The services module’s cold water circuit has a fl ow regulator and connection for an external mains water supply.
Both the cold and hot water system have precision needle valves and turbine fl ow meters to control and measure the fl ow rates.
Thermocouples at the connectors measure hot and cold inlet and outlet fl uid stream temperatures. Some heat-exchangers also have built-in thermocouples for extra temperature measurements. Clear, multiline digital displays show the temperatures and fl ow rates of the fl uid 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 realtime data capture, monitoring and display, calculation and charting of all the important readings on a computer (computer not included).
Available Experiment Modules
• Concentric Tube Heat Exchanger (TD360a)
• Plate Heat Exchanger (TD360b)
• Shell and Tube Heat Exchanger (TD360c)
• Jacketed Vessel with Coil and Stirrer (TD360d)
Note: You need at least one of the optional heat exchangers to do experiments. TecQuipment recommends that you buy the Concentric Tube Heat Exchanger (TD360a) fi rst, because it has extra temperature measuring points.
Recommended Ancillaries
• VDAS-F (frame-mounted version of the Versatile Data Acquisition System)
