🌱 FR3 Natural Ester (Less-Flammable Fluid Fire Point >300°C, NEC 450-23 Clearances)

Transformer Ester Fluid vs Mineral Oil Calculator

Evaluate less-flammable natural ester dielectric fluids (Cargill Envirotemp FR3 / MIDEL) versus conventional mineral oil in substation transformers: calculate fire point safety ($>300^circ ext{C}$ vs $160^circ ext{C}$ for mineral oil per NEC 450-23 allowing reduced building clearance setbacks and elimination of fire barrier blast walls), and clean-tech yields.
