Description

The bench CHP CO2 is made to study a cold room using this new fluid. The system includes a condensing unit using CO2 and a cold room with air evaporator.

The transparent sides of the condensing unit are made to view the inside of the unit. To be able to study the system, the refrigerated circuit is equipped with pressure and temperature sensors.
Student can work on identifying the components, commissioning adjustment and the verification of good working order

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.
