LOW POUR OIL Series
 

Description

These oils have been blended with highly refined paraffinic mineral base oils having low pour points and good oxidation resistance. PSO Low Pour Oil provides excellent lubrication for many industrial and processing applications. The oils are incorporated with selective pour point depressant to lower the pour point beyond the neutral capability of oils.
 

Applications

  • PSO Low Pour Oil is a range of lubricants designed to meet requirement of low temperature operations of various type of refrigerators and air conditioning compressors using halogenated refrigerant such as Freon etc. These are low cost locally blended products which do not claim meeting international specifications laid down for oils used in refrigerator and air-conditioning compressors. However, their market acceptability is good as a local suitable product.
     

Benefits

  • Good oxidation stability.
  • Good rust protection.
  • Low Pour points.
  • Resists formation of deposits in high temperature parts of refrigeration system.
