Providing a renewable source of energy, wind turbines are constantly gaining ground. However, many turbines are located in places where access is difficult making maintenance such as re-lubrication of bearings a tough task.
A normal re-lubrication interval is somewhere around six months. No wonder people raised their eyebrows when we suddenly claimed we had developed a lubricant that extended the re-lubrication interval for the main bearings by a factor of eight. But it was true. Epoch™ technology was born.
By using a non-polar thicker system (polypropylene), almost all additives could easily reach the metal surfaces of the bearing. This, in turn, made it possible to minimize the amount of additives and improve lubricating performance.
