TYRENO FLUIDS

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. multiple-stage 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 (following to 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.

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
