Description

The positive refrigeration kit allows the study of a positive refrigeration system. The system includes all the standard components such as compressor, condenser, expansion valve, evaporator, cylinders, pressure switches.

The kit is delivered complete, assembled and functional. Students will be able to work on component identification, commissioning, adjustment and verification of proper operation. They will also be able to recover the fluid and charge (requires tools not supplied with the bench).

The kit is designed to be assembled with DIDATEC type CHB100 cold rooms.

The rugged design of this equipment makes it perfectly suited for use in a school setting.

Its anodized aluminium structure on wheels gives it a very high robustness as well as great flexibility of integration into your premises. The manufacture of this equipment complies with the European Machinery Directive
