The polymerization of HFO R1234yf results from a chemical reaction that occurs under certain temperature and humidity conditions. Under these conditions, hydrofluoroolefin molecules can interact with other substances, causing the refrigerant to solidify as it expands. This solidification can clog the hose, drier, expansion valve, or even the compressor, resulting in significant repair costs. Identified causes: - Residual traces of certain additives used for cleaning refrigerant cylinders, which were not sufficiently removed before refilling. - Contact between R1234yf and lubricants or substances containing hydrocarbons. This phenomenon has been observed on two occasions: when refilling the station from a new refrigerant cylinder, and when filling the air conditioning system with refrigerant from the station’s reservoir. The CLAS AC 2034 polymerization monitor is not permanently installed between the cylinder and the station. It is used as a one-time diagnostic tool immediately before the transfer. How it works in practice: Direct connection: Screw or connect the tool directly to the valve of your new R1234yf cylinder. Test phase (the "spit"): Briefly open the cylinder valve to allow the gas to expand through the tool (into the air/via the built-in filter). Thermal expansion immediately causes solidification (polymerization) if the gas is contaminated or of poor quality. Visual inspection: Check the condition of the tool’s transparent filter in a few seconds. If the filter remains clean and the gas flows freely, the refrigerant is compliant. If you observe a solid deposit or a blockage, the gas is defective (under no circumstances should you introduce it into the service station). Connecting the system: Once the test is confirmed (in a few seconds), close the cylinder, remove the AC 2034, and you can safely connect your air conditioning system to recharge its internal reservoir. Note: Be sure to clean the tool’s filter after each test to ensure it can be reused. |
