This increases the potential for explosion, fire, deterioration of lubricants and equipment failure. This chemical reaction with standard lubricants can result in: • Accelerated decomposition of hydrocarbon lubricants • Bearing failure due to tars and varnishes • Reaction with additives leading to degradation and reduced lubricant life • More frequent lubrication • Need for explosion-proof barriers and nitrogen purge to keep non-compatible lubricants below explosive limits • Costly, cumbersome equipment with interlocks that can fail • Risk of compression auto-ignition when standard lubricants make contact with an oxygen surge • Lubrication system failure from oxidation, harsh chemical or solvent attack, flammability and volatilization of the oil base of standard lubricants The Solution DuPont™ Krytox™ NRT oils and greases are designed specifically for critical oxygen service equipment where failure is not an option. With more than 40 years of experience, DuPont offers lubricants that meet the demanding needs of oxygen and reactive gas applications. Krytox technology delivers: • Safety in use with oxygen and other chemicals, including fluorine, chlorine, bromine, and HF • Nonflammability that may allow elimination of auxiliary systems to prevent fire and explosion • Extended equipment life • Grades of Krytox oil and grease available for every oxygen and compressed gas lubrication requirement • Robust, soluble, anti-wear/anti-corrosion performance • No auto ignition at temperatures up to 900°F in oxygen • No ignition at pressures up to 350 bar Demonstrated Results Krytox technology provides state-of-the art performance for mechanical systems under harsh conditions. From gearboxes, bearings and chains – to seals, actuators, valves, and more – every day Krytox serves the specialized needs of: • Pulp and paper mills and converting plants • Automotive components • Military and commercial aircraft • Chemical plants • Power plants • Turbine generators • Oxygen, chlorine, and reactive gas equipment and compo- nents. DuPont lubricants have been independently tested by organizations such as BOC, Air Liquide, BAM, NASA, General Dynamics, and Praxair and proven acceptable for oxygen and other reactive chemical compatibility.
