Standby power / rotating assets
Critical equipment lubricant analysis
Condition monitoring for standby-generator, chiller and compressor lubricants that support data-center resilience.
Analytical position
Test the fluid that is actually in service.
Generator and rotating-equipment lubricants need chemistry-specific machinery-condition methods, not a transformer-oil slate. ASTM D7414 applies to petroleum and hydrocarbon lubricants; ester-based compressor and refrigeration oils require a separately validated route.
Condition signals
What we can examine.
Kinematic viscosity
Wear, additive and contaminant elements
Water by Karl Fischer
Acid number and oxidation trend
Particle count where applicable
Fuel dilution or coolant ingress investigation after chemistry review
Questions the report should answerHuman review
Has water, fuel or coolant ingress altered the lubricant?
Does the evidence support continued service, resampling or intervention?
Each answer combines suitable results, baseline history and operating context. No conclusion rests on one isolated number.
