Edwards ULTRAGRADE™ Performance oil 15, 19, 20 and 70 are produced by a unique hydrotreating process. This process eliminates nitrogen, sulphur and oxygen and the aromatic hydrocarbons. The end product is a clear base stock essentially free of impurities.
When combined with additives, the ULTRAGRADE™ Performance oils give improved vacuum performance, thermal and oxidation stability and rust inhibition. The anti-oxidants included in the oils enable the pump to withstand high operating temperatures without oil degradation, so extending intervals between oil changes.
The properties of the oils allow them to be used in a wide range of applications. New ULTRAGRADE™ Performance oils are the best choice for large pumps used in heavy-duty, cycling applications.
