Table Top Refrigeration Trainer Model RAC 006

Sci-tech Basic Table Top Refrigeration Trainer Model RAC 006 is designed to provide students with a thorough understanding of various types of systems used in commercial and industrial applications. It permits students to understand the refrigeration cycle, including measurement of pressure, vacuum, flow rate and temperature.

Sight glasses at inlet and outlet of evaporator and condenser allows students to monitor changes in refrigerant state. The system components are panel mounted to provide easy access for testing and trouble-shooting.
