Featured Applications
FR3® fluid is ideal for transformer fluid applications in renewable energy generation, retrofilling and power distribution and transmission.
Battery energy storage systems (BESS)
Battery Energy Storage Systems (BESS) are essential for grid stability and maximizing renewable energy value. Pairing them with FR3 fluid elevates fire safety, reliability, and long-term performance—delivering the confidence modern energy storage demands. Explore how FR3 fluid can strengthen your BESS strategy.
Data centers
As data centers scale to meet the demands of AI and infrastructure digital growth, energy networks are being pushed harder than ever. FR3 fluid is engineered to support what matters most: uninterrupted operation. In emergency or overload conditions, it can handle up to 20% more load than mineral oil—without compromising long-term transformer reliability.
Power Transmission and Distribution
FR3 fluid is proven across power generation and distribution transformers in every voltage class. Compared to mineral oil, it delivers superior performance and measurable cost efficiencies for utilities. Choosing FR3 fluid strengthens grid flexibility and resilience—benefiting your business and your community.
Retrofilling
FR3 fluid-filled transformers can extend paper insulation life by up to 8 times compared to mineral oil units, thanks to FR3 fluid’s superior moisture-handling capabilities. It also delivers significantly improved fire safety, with a fire point more than twice that of mineral oil. When you retrofill a mineral-oil-filled transformer with FR3 fluid, you gain both extended asset life and a significantly reduced risk of fire.
Solar power
FR3 fluid is widely used in both land-based and floating solar applications across the globe.
Solar farm transformers benefit from FR3 fluid’s higher flexible loading capacity and minimal maintenance needs. The fluid’s sustainability advantages reduce environmental impact while allowing for smaller installation footprints and improved fire safety compared to mineral oil.
Wind power
Demand for wind power continues to grow, and turbines for large scale wind farms are becoming more powerful than ever. This makes it essential to specify compact, lightweight, low-maintenance transformers that can keep pace with these demands. FR3 fluid helps wind turbine transformers—onshore and offshore—meet these requirements while delivering meaningful cost and performance advantages.
