FR3^® Fluid: The smartest choice in dielectric fluid

For more than twenty years, FR3 fluid by Cargill^® has outperformed mineral oil in distribution and power generation transformers of all voltage classes worldwide. Derived from 100% renewable vegetable oil, FR3 fluid is the smartest choice ‒ you won't compromise between generating business profit, enabling flexible and reliable performance, serving people in your community and benefiting the planet.

Compared to mineral oil, tested and validated FR3 fluid delivers cost efficiencies and business value through:

Enhanced load capacity and grid resiliency
Enhanced performance, including in extreme environments
Extended asset and insulation life
Significantly improved fire safety
Superior environmental benefits
The power of Cargill

FR3 fluid in your transformers can deliver proven, concrete results:

17% average NPV cost savings
20% extended loading or load capacity
Up to 5 to 8 times longer insulation life
Up to 50% extended transformer life
2 times the flash and fire point of mineral oil
100% biodegradability in 10 days

FR3r^™ Fluid: The fluid that works harder and smarter

Derived from over 95% rapeseed/canola oil, a renewable resource, FR3r^™ natural ester is a higher performing, more reliable, and more sustainable dielectric fluid compared to mineral oil. FR3r fluid meets or exceeds all IEC 62770 and IEEE C57.147 standards.

The main advantages of FR3r fluid are:

Exceptional reliability
- Easily handles high heat with up to 140°C top fluid temperature limit (according to IEC 60076-14 and IEE C57-154)
- Continuously dries paper insulation without creating any damaging byproducts or sludge for up to 8 times longer paper insulation life
Increased loading capacity
- Up to 20% more loading capacity compared to mineral oil
- Design a smaller transformer with the same loading capacity, the same sized transformer with up to 20% more loading capacity, or any combination in between
More sustainable
- 100% biodegradable in as little as 10 days
- Non-toxic in water, soil, and to wildlife and humans
- Derived from more than 95% rapeseed oil, a renewable resource
Superior fire safety
- Over 2 times higher fire and flash points compared to mineral oil
- K-class fluid with an exceptionally high fire point of 360°C
Cost savings
- Design a more power dense transformer and save on expensive materials like steel, aluminium, copper, and insulating paper
- Eliminate downtime and save valuable resources with no maintenance needed under normal operating conditions
- Remove or greatly reduce expensive fire remediation and spill containment systems with K-class fire certification and 100% biodegradability

SE3^™ Synthetic Ester Fluid

SE3^™ fluid is Cargill's next generation of synthetic dielectric transformer fluid.

Brought to you by the makers of FR3^® fluid and FR3r^™ fluid, SE3 fluid completes the portfolio of transformer fluid solutions as superior options to mineral oil.

With exceptional performance, SE3 fluid greatly complements the needs of some specific transformer applications by delivering a high performance K-class fluid, optimized for extreme cold weather and suitable free-breathing transformers.

The key features of SE3 fluid are:

High fire point of > 300 °C (compared to 160 °C for mineral oil) allows its classification as a K-class, less flammable liquid
High thermal class dielectric liquid, suitable for use in free breathing applications
Continuous flow even in extremely cold climates, pour point down to -50 °C
Optimized for oxidative stability
