High Pressure Environment
Friction Tester

Although the last few decades have made a shift from using harmful Chlorofluorocarbon refrigerants to alternatives like HFC, this decade is bringing a new shift to using Green refrigerants like CO2, NH3, HFO, R32, R134a, propane, etc. Developing and testing components that use these new green refrigerants will be required to be friction tested in a high-pressure environment.  Our tester is perfect for automotive suppliers who manufacturer air conditioning systems and appliance manufacturers of freezers, refrigerators, and air-compressors.

 Use Case: In recent rotary compressors, the lubrication area exists on the high-pressure part of the compressor, it requires to conduct friction tests under high pressure environment. For example, CO2 gas dissolves in lubricating oil at high pressure, changing the lubricating effect. The test applies the same contact force as it would during real operation to the material of the compressor (e.g. vane vs rotor), and measures the change in the coefficient of friction.
