Retrofilling

Fires involving mineral-oil-filled transformer are more frequent than most people think, and they can cause catastrophic damage to equipment and people. FR3 fluid has more than twice the flash and fire points of mineral oil. In 25+ years, there have been zero reported pool fires in transformers filled with FR3 fluid. FR3-fluid-filled transformers can also be installed with highly simplified containment and can eliminate the need for costly fire-mitigation systems, which may mean reduced insurance premiums.

FR3 fluid’s unique chemical properties allow it to manage moisture dramatically better than mineral oil, avoiding dielectric failure and asset aging in ways that mineral oil simply cannot. FR3 fluid holds over 10X more dissolved water than mineral oil and thereby mitigates the risk of dielectric failures while extending the life and preventing the need of maintenance intervention.

Compared to mineral oil, FR3 fluid allows you to run your transformers 20°C “hotter,” increasing load capacity up to 20%. This allows your grid to easily respond to fluctuating load demands—without accelerating asset aging. As increased power demands and an expanding population place stress on your grid, retrofilling with FR3 fluid helps your business meet customers’ needs like never before.

Made from vegetable oil, with performance-enhancing additives, FR3 fluid is the industry’s first and leading natural ester dielectric fluid. Unlike mineral oil, it is nonhazardous and nontoxic in water and soil.¹ It is also 100% biodegradable in as little as 10 days. Due to these features, transformers filled with FR3 fluid require simplified spill containment and remediation. In fact, bioremediation in case of a spill typically does not require costly equipment and labor.
