We analyze lubricating oil used in engines working in cogeneration systems (CHP), with biogas as the primary fuel.

For the evaluation of the efficiency of the filters we set the levels of metal impurities and additives as well as the amount of pulp (remains of the consumption of the device)

• Viscosity at 40 ° C, cSt
• Viscosity at 100 ° C, cSt
• viscosity Index
• Water%
• Oxidation, Abs / cm
• Nitration, Abs / cm
• The content of the refrigerant fluid
• TAN mg KOH / g (acid number)
• TBN mg KOH / g (base number)
• The metal content of wear-own ppm
• The level of additives, ppm
• The level of pollution, ppm
