Product Name: Basic Refrigeration & Freezing Trainer

Model Name: YESR-2000

Technical Description

• It is able to make the experiments and training for temperature,  

   pressure-control device and auto defrosting

• It is able to check the changes of refrigeration device depends 

• It is able to set up the temperature scope of measurement to create the 

   P-I diagram so it makes these experiments and trainings available 

   of equipment, Mollier diagram, and data saving.

• Theoretical education, experiments and trainings are available for the fundamental 

    circuit and application circuit by various circuit structure of equipment

• It is able to understand the principles of hot gas defrost. 

• Unlike separation system in mechanical part, the control unit is visualized.
