Description

The CRM011 trainer  allows the study of a refrigerated showcase. Students will be able to identify the components of the machine, make the commissioning, record the operating parameters.

It is composed of a classic window found in supermarkets.

Breakdowns can be created by the teacher to allow the student to work on curative maintenance.

The robust design of this device makes it suitable for use in schools.
The equipment is set up on an Anodized aluminium frame on casters wheels. This gives it great strength and a flexibility of integration into your premises.The manufacture of this equipment complies with the European standard for machinery manufacturing.
