Teaching equipment : Refrigeration cycle demonstration unit with air or water

Refrigeration cycle demonstration unit with air or water

DESCRIPTION   The bench is delivered complete with instrumentation, technical manual and practical work. Designing, manufacturing and industrial standards. This unit can be used at different level sand in different field sof study. This bench has the same functionalities as the CRD 400 with the possibility to operate with a condenser with water or air.

The use of the refrigerated fluid R134a is conform to new regulations.
