RAC1
Labtech has designed a special flexible training system for the teaching of refrigeration and air conditioning
electrical controls. The program covers the operation, use and wiring of refrigeration and air conditioning
controls, compressors, electrical motors and basic electrical installation. It consists of real industrial components
mounted on to clear plexiglass panels which are then inserted into the special frame. This allows the student to
quickly assemble the components into various types of operational systems and explore their functions and
characteristics.
This trainer is not only ideal for exposing and giving practice in the basic of refrigeration and air con controls
but also can be used for making up special demonstrations of a variety of control systems to match specific
training programs. Complete systems can be mocked up or the controls can be connected to other installations
or trainers to provide additional features.
All electrical connections of the components are brought out to 4 mm heavy duty terminals. Connections are
made with stackable electrical test leads, which allow the student to make quick connections and easy
measurements. Refrigerant connections can also be made with flexible hoses in order to create fully operational
systems. A variety of modules are available to suit particular training requirements. Student exercise
sheets are including to covering the components and basic electrical connections.
