TESTOIL-3P-CO2 compatible with the oils used in CO2 installations (POE, PAG, PAO etc.)


The oil acidity content is an important parameter to check because it determines the refrigerating installation’s good operating condition. Two internal chemical processes can alter the oil quality and generate the formation of acids and sludge harmful for the installation:

  • The formation of free fluorinated and chlorinated acids produced by alteration of halogen refrigerants;
  • The formation of fatty acids by hydrolysis of POE-type oils.

These acids then generate metallic salts and oxides (iron or copper) that could block the oil filter or lead to the copper plating of metallic parts in motion. These degradation phenomena are dangerous for the installation, because they lead to seizing of oil pumps and to severe damage due to lubrication defect.

The new oils (mineral, alkylbenzenes, polyvinylether and polyol-esters) have different acidity indices due to the addition of (anti-wear, antioxidant, anticorrosive...) additives by the manufacturer, in order to reduce mechanical wear and extend the compressor’s service life.
