UV LEAK DETECTION IS ADDED TO THE COMPRESSOR OIL. Non-hygroscopic! PAO-Oils do not absorb any moisture from the air and can therefore be stored for a long period even after opening. Suitable for all types of refrigerants. PAO Oil 68 Plus UV has the same advantageous properties as PAO Oil 68. It is additionally enhanced with a concentrated, highly effective contrast agent that is used for UV leak detection. The advantage of the low Vol %-concentration of the contrast agent is that all the properties of the oil are retained and there are no negative effects on system components or service units whatsoever. To achieve a sufficient effect during troubleshooting, only 10 Vol % of the system oil quantity are quite adequate. This corresponds e.g. to only 18 ml PAO Oil 68 Plus UV when the total system oil quantity is 180 ml. In addition, PAO Oil 68 Plus UV can also be used for filling the whole system without there being any negative effects. PAO Oil 68 does not have any harmful effects on fluoroelastomer materials, such as hoses or seals, and is ideally suited for converting from R12 to R134a refrigerant. Product Features:Suitable for all types of refrigerants.Compatible with all other lubricants.Extended operating range from -91F/ -68C to +599F/ +315C.No accumulating in evaporators or condensers.Higher cooling performance with less energy expenditure.Reduction of the friction between the componentsReduced energy consumption of the compressorReduction of the compressor noise level.Many years of successful practical use.Low Vol %-concentration of the highly active contrast agent PAO Oil 68 Plus UV, which means protection and reduced wear of the system components and service units The molecules of the PAO Oil 68 adhere to all surfaces in the system, force out other molecules and remain as a thin layer on the surface of the system components. Due to the fact that the molecules do not try to connect to each other, this oil layer is just one molecule thick. Unlike many other oils, there is therefore no risk of oil collecting in the evaporator and the associated deterioration in cooling performance when PAO Oil 68 is used. Due to the fact that PAO Oil 68 only slightly connects to the refrigerant, only a small part of the oil circulates through the system. The rest stays where the oil is actually needed in the compressor. An oil film in the components improves the seal and/or reduces the friction between the moving parts in the compressor. This reduces the operating temperature and the wear. This plays an important role in the operating safety and reduction of noise and also ensures lower run-times and less energy consumption by the compressor.
