II. Description of Actrel3363L/1178L Product Characteristics:

1. Wind turbine maintenance includes cleaning critical components such as bearings, which is essential for maintaining turbine efficiency and enhancing wind power generation capacity. Selecting the appropriate cleaner and suitable grease helps extend bearing life. Mobil Actrel Fluid Cleaner is a reliable cleaning solution that thoroughly removes aged, hardened grease. By combining Actrel Cleaner with Mobil Grease? Wind Turbine Grease to prevent premature bearing damage and protect against rust and corrosion, you can benefit from a complete maintenance solution.

2. Effectively Removes Hardened Grease

Actrel3363L/1178L Fluid Cleaners have superior wetting ability due to their low surface tension (24.14–26.8 Dynes/cm at 20°C, compared to water's surface tension of 72.8 Dynes/cm at 20°C), providing better spreadability and the ability to flow through tight spaces in complex components, such as small blind holes or part clearances that are difficult to clean and dry.

Compatible with Most Plastics, Metals, and Elastomers

Actrel3363L/1178L Fluid Cleaners do not harm bearings during cleaning as they are compatible with most polymer materials and nearly all metals.

Potential to Improve Cost Efficiency

Unplanned failures can cost asset owners up to $30,000 per turbine annually in repairs and spare parts, along with up to 7 days of production loss per year—not including production losses due to planned downtime or the time required for materials, equipment, and technicians to reach the affected turbine1. Effective cleaning of grease in wind turbines may help reduce operational and maintenance costs.
