Mobil SHC Rarus Technical Deck;Mobil SHC Rarus Overview;Mobil SHC Rarus has demonstrated the capability to last more than 24,000 hours in service in a rotary screw air compressor Mobil SHC Rarus has the potential to deliver up to 3 times oil life versus a leading synthetic compressor oil* Mobil SHC Rarus is backed by a limited warranty which covers: Up to three years or three times the length of the current fluid’s oil drain interval, up to a maximum of 24,000 hours ;Limited Warranty;Balanced Performance;Summary;Overview with Links to Key Slides;Driver for Test Allows evaluation of candidate formulations in real world equipment with reduced cycle time Oil life in compressor test gives relative indication of expected field performance No industry standard compressor tests available Equipment Evaluate fluid performance in a commercial oil-flooded rotary screw air compressor Modifications to increase severity Increase oil sump temperature to 130°C Preheat and humidify intake air No make-up oil Controls Monitor and control key operating parameters Measurements Monitor oil conditions during test End of test Oil condition TAN ≥ 3 mg KOH/g Rate equipment parts for varnish and sludge Photograph screws;1X;Varnish Sludge Control;;Oxidative stability was compared based on results of Testing under dry conditions PNEUROP Oxidation Test (DIN 51352) PNEUROP (European Association of Manufacturers of Compressor, Vacuum Pumps, and Pneumatic Tools) Test evaluates lubricant resistance to oxidation. Oil is heated to 200°C for 24 hours with air blown through the sample. The percentage of oil lost due to evaporation is used to evaluate field performance of an oil. Test Relevance: Evaporative loss under oxidation can lead to oil thickening, which can lead to decreased cooling capability of the oil and need for additional top up. Testing in the presence of water Rotary Pressure Vessel Oxidation Test (RPVOT, ASTM D 2272) Provides a rapid determination of resistance to oxidation.
