Abstract Information :
In the oil industry, some of the oil fields are found far up north where temperatures can reach as low as -30C and lower. When working with metal machinery it is important to have them constantly lubricated to prevent any damage to the components. Certain greases do not perform properly in low temperatures, especially at extreme negative temperatures. Greases are made from a base oil and that base oil determines how the grease performs under certain conditions as well as its operating temperature. Certain greases that use certain base oils to help them gain the ability to perform well at low temperatures, such as esters and perfluorinated polyether PFPEs, while other base materials are better suited for higher temperatures, such as mineral oil. Either way, it is important to test out how well the grease performs in low temperature settings and gain other valuable information about how the grease performs prior to being applied in the field and used in machinery. The K95300 Low Temperature Grease Flow Tester is designed to test greases and evaluate how greases perform in low temperature conditions. The Kesternich method DIN-51805 is applied in accordance with the instrument to test out how greases perform up to -50C, along with evaluating other properties of the grease at low temperatures. The following poster will go in more depth about the Kesternich method and the specifications, capabilities, and applications of K95300 Low Temperature Grease Flow Tester.rn
