NP Process Oil

Overview

NP Process Oils are manufactured from premium quality hydro-treated base oils. They are suitable for general-purpose lubrication where non-additive oils meet the lubrication requirements.

These oils offer the following benefits:

  • Good oxidation stability
  • Good Demulsibility
  • Moderate low temperature flow characteristics
  • Low volatility
  • Low carbon forming tendency
  • High thermal stability

MAIN APPLICATIONS

Reciprocating air compressors with air discharge temperatures up to 100 oC.Heat transfer fluid for closed heat transfer systems up to 320 oC.As plain and rolling element bearings, spur, bevel, helical and worm gear box lubricants, where temperatures and loadings are light to moderate.General machine lubricants where straight mineral paraffinic oils are recommended.

The low viscosity grades (ISO V.G. 22 to 46) find general economic applications as:Non-compounded light coloured sewing machine lubricantsAir line lubricantsVacuum pump lubricants
