The TU-420 Refrigeration Trainer Demonstrator is a fully operational, self contained refrigeration cycle (vapor compression type). It is properly charged with refrigerant R-134A at the factory and may be set into service merely by plugging the power cord into a conventional 110V outlet. The main power on/off switch is located on the front panel of the unit. Using the four main parts of the refrigeration system (condenser, compressor, evaporator and control device), this unit demonstrates basic refrigeration principles. These components then work together to cool a small enclosed refrigerator compartment fully featured with an electronic temperature control device.
