Why FR3 Fluid
For the performance you want and the reliable power your communities need, FR3 fluid beats mineral oil—it’s that simple
Mineral oil has helped light and power the globe for more than 120 years. But for decades, another option has proven better. FR3 dielectric fluid—derived from 100% renewable vegetable oils—delivers what transformer mineral oil can’t: peace-of-mind reliability with exceptional performance, improved fire safety, and better-for-the-planet biodegradability, along with related cost savings.
FR3 fluid’s superiority over mineral oil can benefit you and the communities you serve. Get FR3 fluid details.
Designed to deliver—with none of the drawbacks of mineral oil.
You may think that mineral oil is a “good enough” insulating fluid for your transformers. But isn’t it really just the devil you know? Using mineral oil comes with significant risks—of devastating pool fires, dielectric failure due to low moisture tolerance, a quick darkening of the oil if the transformer is overloaded, and costly environmental damage in case of leaks or spills.
Since these risks are always present when you choose transformer mineral oil, “not good enough” may be just one week, one day, or even one minute away.
Ultimately, the risk won’t be worth it—and the consequences may be serious, to people, equipment, and your reputation. With FR3 fluid, you avoid the pitfalls that accompany mineral oil and get a superior dielectric fluid with measurable, validated, verified results.
Delivering business value
There are a number of different critical reasons why partnering with Cargill and using FR3 fluid instead of mineral oil is good for business, including increased grid reliability and resilience, better cost management with a more effective transformer system, and minimized environmental impact.
