Description

The negative refrigeration unit allows the study of a negative refrigeration system. The system includes all standards components such as compressor, condenser, regulator, evaporator, bottles, pressotats.

The system comes completes, assembled and functional. Students will be able to work on components identification, commissioning, adjusting and checking for proper operation. They will also able to recover the fluid and load (requires tools not provided with the unit).

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

Its anodized aluminum structure on wheels makes it extremely robust as well as great flexibility of integration into your premises. The manufacturing of this equipment meets the European machine directive
