Quote from one of the UK guys who seems to know:
"Purity The quality of commercially available propane (LPG) is very often not suitable for refrigeration. The composition varies substantially, generally having between 60 and 95% propane. It can have high levels of moisture and unsaturated hydrocarbons. Impurities such as other hydrocarbons can impact the vapour pressure of the product, lowering overall system efficiency. Sulphur can cause corrosion, and unsaturated hydrocarbons can react with system components. Moisture leads to hydrolysis, corrosion and compressor failure. R290 is at least 97.5% pure with minimal levels of critical impurities including moisture (typically† <10ppm), unsaturated hydrocarbons (typically <0.5%) and sulphur. This makes it ideal for use in all types of refrigeration and air conditioning systems." Maybe all that is needed is to run it through a proper filter system to meet the requirements? That is something else to be checked out. |
