Description

The CRE302 bench allows the study of a compression plant with three stages. It is composed of a plant equipped with three semi-hermetic industrial compressors and three evaporation systems (negative cold room, positive cold room and evaporation into the atmosphere). The system includes all the standard components equipping the industrial plants (oil separator, dehydrator, constant pressure expansion valve  ...). In addition to this the bench is instrumented in order to expand its pedagogical use.

Students will initially understand the system and identify the components of the installation. They can then do commissioning and the necessary settings (pressure switches, regulators, constant pressure expansion valve ...).

When the system is in operation then they can check the parameters (pressure, temperature, flow rate  ...). They will calculate the efficiency and will draw the enthalpy diagram corresponding to each evaporation system.

In a later time, they can perform maintenance operations such as changing a filter, the change procedure of a compressor on a plant, the change of an evaporator, the manifold fitting.

The robust design of this equipment makes it perfectly suited for use in schools.

Its anodized aluminum structure on feet gives it great robustness as well as great flexibility of integration into your premises. The manufacturing of this equipment meets the European machine directive
