– Reliable operation of vacuum pumps as well as installations and components using gaseous oxygen
– due to low oil vapour pressure
– due to very low tendency to thermal ageing
– due to good chemical stability and resistance to aggressive media
– due to high oxygen pressure surge resistance (see product data)
– Versatile sliding agent
– for industrial handling of oxygen, air, carbon dioxide, inert and other gases as well as their condensates
– for maintenance and care of breathing apparatus on the low pressure side
– Each production batch is checked for its reactivity with oxygen
Klüber Tyreno Fluids are fluids designed to meet the special requirements of modern vacuum pumps.
Klüber Tyreno Fluids 3/6 V, 6/14 V, 12/25V are perfluorinated polyether oils (PFPE) which are available in different viscosities and show particularly high chemical stability.
They are used whenever aggressive media must be pumped, e.g. oxygen, and / or high-vacuum conditions (e.g. multiplestage
pumps) prevail. Klüber Tyreno Fluids show a high resistance to a wide range of chemicals. To ensure continuous adherence to this high quality standard, these fluids are manufactured in small series subject to strict hygiene requirements and each batch is inspected for resistance to gaseous oxygen (acc. to Annex of Code of Practice M based on M 034-1 list of nonmetallic materials (213-075).
Klüber Tyreno Fluids are tried-and-tested as filling fluids in mechanical backing pumps, diffusion pumps and turbomolecular pumps by leading OEMs. They are also suitable for pumping gasous oxygen. Klüber Tyreno Fluids have been tested as filling fluids according to the Autogeneous Ignition Temperature (AIT) procedure. Klüber Tyreno Fluids can also be used as vapour-resistant, chemically inert transmission fluid in dry-running screw-type pumps.
Klüber Tyreno Fluids can also be used as sliding agent for the lubrication of valves, fittings and installations carrying gaseous oxygen or for chemical plants and apparatus requiring good resistance to various gases (conclusion by analogy based on chemical composition. For this purpose, we recommend users conduct their tests using the complete component under conditions similar to series application. Test results show the products’ usability for an O2 content > 21 % by vol. under operating conditions specified in the product data section of this product information leaflet. Behaviour towards metal, elastomers and plastics Klüber Tyreno Fluid 3/6V, 6/14V, 12/25V are normally neutral towards metallic materials, plastics and elastomers within the envisaged temperature range. Nevertheless, we recommend checking the compatibility of the product with materials prior to the introduction of this product.
All surfaces to be wetted must be thoroughly cleaned prior to product application. The friction and lubrication points of these surfaces/components must be clean and bright (i.e. free from oil, grease, dirt particles or perspiration, etc.). For optimum lubrication results, we recommend cleaning the friction points with clean white spirit and then Klüberalfa XZ 3-1, ensuring residue-free surfaces when dried. Application to equipment, valves and fittings carrying oxygen must also be “oxygen clean” to attain a “ready for oxygen service” condition. For use at low temperatures, e.g. where components are in direct contact with liquid oxygen, experimental testing and approval by the component manufacturer is required since the design and power ratings, for example in actuator gears, may play a decisive role in this context.
