Description

The CMF100 bench allows the study of a cascade compressor plant. It consists of two semi-hermetic industrial compressors connected in cascade by means of a plate exchanger and a cold room in which a forced convection evaporator is placed. The primary stage works with a medium-temperature fluid and the secondary stage with a low-temperature fluid. The system includes all the standard components used in industrial power plants (anti-liquid bottle, dehydrator, regulator, etc.). In addition to this, the bench is instrumented in order to expand its pedagogical exploitation.

Students will first need to understand the system and identify the components of the installation. They will then be able to make the necessary commissioning and adjustments (pressure switches, regulators, regulator, regulator, etc.).

When the system is in operation, they will be able to check the parameters (pressure, temperature, flow rate, etc.). They will calculate the yield and plot the enthalpy diagram for each stage of the system.

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

Its anodized aluminum structure on wheels gives it great robustness as well as great flexibility of integration into your premises. The manufacture of this equipment complies with the European Machinery Directive
