RULER technology, replacement technology for RPVOT testing -

In both Europe as well N. America we see a general trend with the new generation of (long-life, high temperature turbine oils) to start using RULER method, replacing the RPVOT test methods.

Not only are turbine manufacturers designing their turbines and compressors to work with operating temperature conditions for lubricants which have increased significantly, but also will they be used to a longer drain interval (by avoiding unnecessary downtimes).
Add to that the increasing use of combined cycle power plants, which are not operating under continuous regime, but from peak-to-peak conditions, and which are also stressing the oil more significantly.
With those 2 factors, turbine and compressor operators, have been modifying their antioxidant chemistry to the latest standards, and which requires a close monitoring of the antioxidant concentrations during the lubricant use.

RULER Technology will bring the solution to this new requirement, and RULER as a field test is not only faster to perform, but it will also enable users to perform a trend of individual antioxidant consumption during the lifetime of the power generation lubricants. How the RULER method correlates with RPVOT, you can see on the following page

Ø     The RULER test is an ASTM approved field test, bringing the oil analysis to the field

o      Bring the oil analysis at your fingertips

Ø     The RULER test is faster and less expensive to perform vs. RPVOT

o      In less than 1 minute you have a full view on the condition of your in-service oil

Ø     The RULER test will monitor individual antioxidants consisting of aromatic amines and phenols, rather than just a RPVOT result in minutes

o      Differentiate Antioxidant depletion, and take corrective actions from the differences in AO depletion

Ø     The RULER test allows to perform a Trending curve, as part of CBM-strategies
