Key features

• One of a set of optional heat exchangers for use 
• Popular type heat exchanger, used in industry but designed for teaching
• Simple and safe to use, its foolproof fi ttings allow students to change and connect the heatexchanger quickly and easily without tools
• Clear outside casing, so students can see its construction
• Bedplate with a clear schematic diagram to help students understand how to connect the heat exchanger
• Corrosion-resistant materials for use with ordinary clean water at safe temperatures

Description
This heat exchanger is a set of metal plates separated by spacers (gaskets). The plates and gaskets have holes that make the hot and cold fl ow run on alternate sides of the plates, therefore transferring heat. The metal plates have flow disturbers on their sides to help improve the heat transfer.

Plate heat exchangers are compact and therefore good for applications with limited space. It is also easy to alter their design to change their capacity you simply add or remove plates and spacers. The Service Module provides hot and cold water to the heat exchanger and all the instruments needed to measure its performance. All fluid connections to the heat exchanger are self-sealing quick connectors for safety and simplicity.

The hot and cold fluid streams have different connectors to reduce errors. Connecting the heat exchanger takes less than one minute. The heat exchanger is on a bedplate that has a clear schematic diagram showing the connections. The bed plate fixes to the service module with thumbscrews (students need no tools).
