Refrigeration Training System

The Refrigeration Training System (3401-2) clearly demonstrates the operation of the most common refrigeration system configurations, including dual evaporator systems. Lockable fault-insertion switches allow students to practice troubleshooting skills, which may be conducted at either the schematic control panel or at the suspect devices and components. Fully integrated courseware guides students through alternative modes of system set-up and control. The training system includes all the equipment required to perform the exercises contained in the courseware. Optional equipment adds to the efficiency of the refrigeration, air conditioning, and heating training laboratories.
