Description

The GEG 106 unit allows the study of an industrial chilled water production system. It is composed of a reversible chilled water unit, a buffer tank and the instrumentation necessary for the complete study of the system.

The students will have to identify the different components of the system (refrigerant and water) and then put it into service. They will then be able to take measurement readings to check that it is working properly and calculate the powers involved

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

Its anodized aluminum 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

This equipment can be used alone or in combination with other compatible equipment in our range (see last part of this document).
