克鲁勃SYNTHESO D220  SYNTHESO D oils Synthetic high-temperature lubricating oils Product information 5.231 e Edition 11.00, replaces edition 05.96 Description: SYNTHESO D oils are synthetic high-temperature oils on a polyglycol basis. They are very resistant to ageing ａnd oxidation ａnd have a very good viscosity-temperature relation. Application: SYNTHESO D oils are used for the lubrication of friction points subject to high temperatures. They are also used as pressure fluids in hightemperature applications, ａnd as heat carrier fluids. Owing to the base oil’s high pressure absorption capacity ａnd good wear protection, SYNTHESO D oils are particularly suitable for hydraulic or heat transfer applications where lubricity has to be ensured at high temperatures. Application notes: SYNTHESO D oils are suitable for immersion ａnd circulation lubrication systems. If they are used as heat carrier fluids it is important not to exceed a specific load of approx. 1.5 W/cm2 in case of free convection ａnd approx. 2 W/cm2 in case of forced convection. The maximum surface temperature of the heat exchanger (film load limit) should not exceed approx. 220 °C. The maximum permanent service temperature of SYNTHESO D oils is approx. 180 °C. Service temperature range*: SYNTHESO D 32: approx. – 40 to 180 °C SYNTHESO D 68 und D 100: approx. – 35 to 180 °C SYNTHESO D 220 bis D 680: approx. – 25 to 180 °C SYNTHESO D 1000: approx. – 20 to 180 °C SYNTHESO D 1500: approx. 0 to 180 °C SYNTHESO D oils are not miscible with mineral oils ａnd synthetic hydrocarbons. We recommend cleaning the lubrication points prior to conversion, ａnd rinsing gears or closed lubrication systems with the SYNTHESO D oil that will be used for lubrication. SYNTHESO D oils are neutral towards ferrous materials ａnd almost all nonferrous metals. There may be increased wear when the contact surfaces of design elements made of aluminium or aluminium alloys are exposed to dynamic loads (sliding speed ａnd high loads). If necessary, wear tests should be carried out. Depending on the temperature ａnd exposure time, synthetic lubricants on a polyglycol base may have an impact on the functional capacity of rubber-elastic sealing materials. Seals made of NBR materials (acrylonitrile-butadiene-rubber) can be used at permanent temperatures up to 100 °C. At higher temperatures we recommend using FPM (fluoropolymers) or VMQ (silicone rubber) seals. It has to be taken into account that different elastomer qualities produced by one manufacturer or different manufacturers may show a different behaviour. Paints may be attacked by synthetic lubricants. When applying SYNTHESO D oils we recommend the use of twocomponent paints (reactive paints). Oil gauge glasses should preferably be made of natural glass or polyamide materials. We recommend testing the suitability of design materials in contact with the selected lubricants, especially for series application. Minimum shelf life: The minimum shelf life is approx. 36 months if the product is stored in the original closed container in a dry place. Pack sizes: 20 kg bucket 180 kg drum SYNTHESO D oils • Good resistance to ageing ａnd oxidation • High service temperature limit • Excellent viscositytemperature relation * Service temperatures are guide values which depend on the lubricant’s composition, the intended use ａnd the application method. Lubricants change their consistency, apparent dynamic viscosity or viscosity depending on the mechano-dynamical loads, time, pressure ａnd temperature. These changes in product characteristics may affect the function of a component.
