| Sampling Refrigeration Compressor Oils |
|
When sampling refrigeration compressor oils, particularly synthetics such as polyalkylene glycols (PAGs) and polyolesters (POEs), it is important that the lubricant is exposed to the air for as little time as possible, especially in humid environments. These lubricants are hygroscopic, which means they absorb uncondensed water vapor directly from humid air. Accurate moisture content reading is vital for the analysis of most refrigerant system lubricants. It is for this reason that the lubricant should be given as little exposure to the atmosphere as possible. Likewise, your laboratory should take equal care not to expose the oil to the air when it carries out its tests. (Ashley Mayer, ABB South Africa)
