Product Details

Technical Description 
Using MT 210, students can develop skills on how to undertake a complex engineering project. The skills developed are the planning, execution and checking of assembly; commissioning, and maintenance operations. The assembly covers installation of the refrigeration components: Installing the low-pressure and high-pressure switches, the expansion valve and the refrigeration circuit piping. The pipe connections are not soldered, but bolted. The electrical installation includes wiring and connecting up all units and switching elements. The tool set ET 150.02 is required to assemble the unit. The ET 150.01 refrigeration charging and evacuation station is required for commissioning the unit.

The fully assembled MT 210 presents a fully functional temperature-controlled cooling system with cooling chamber and electric thermostat. Repeated assembly and disassembly is possible.

The experiment is mounted on a workbench, with drawers to hold components and tools. The assembly panel and refrigeration chamber are mounted on a frame. The frame, condenser set and switch box are permanently bolted to the workbench work surface. The refrigeration and electrical components are attached to the aluminium assembly panel.
The fully assembled MT 210 presents a real, fully functional temperature-controlled cooling system with cooling chamber and electric thermostat. The system is supplied in kit form.
