Description

The PBE 010 trainer allows the study and visualization of the evaporation process in different forms of flow. For this purpose, an evaporating liquid, water, is heated inside a tubular glass evaporator. The pressure can be varied through the cooling circuit. A water jet pump evacuates the evaporation circuit.

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.
