About FR3 Oil

FR3 Oil is a natural ester fluid specifically engineered for transformers and other electrical applications. It provides superior dielectric strength, exceptional thermal stability, and extended equipment life. Recognized globally for its eco-friendly attributes, FR3 Oil is UL-classified as a biodegradable and non-toxic alternative to mineral oils.

Key Features :

  • Superior Fire Safety: High flash point (> 300°C) reduces fire hazards significantly.
  • Eco-Friendly : 100% biodegradable, non-toxic, and derived from renewable plant-based oils.
  • Enhanced Transformer Performance : Increases insulation paper life by up to 8 times, prolonging equipment lifespan.
  • Thermal Efficiency : Supports higher operating temperatures, allowing for greater load capacity.
  • Moisture Tolerance : Absorbs and retains moisture without compromising dielectric properties.
SHRIPARTH FR3 fluid has exceptionally high flash/fire points of approximately 330/360 °C – the highest ignition resistance of any high fire point dielectric fluid currently available. It qualifies as a “high-fire-point”, “less- flammable”, “IEC Class K”.
SHRIPARTH FR3 fluid is compatible with standard transformer construction materials and components. SHRIPARTH FR3 fluid should be stored, handled, and processed in a similar meticulous manner as transformer mineral oil,
FIRE SAFETY

FIRE SAFETY

SHRIPARTH FR3 fluid has a fire point of approximately 360°C, well above the minimum of 300°C required for high fire point fluid classifications. Its flash point (approximately 330°C) is higher than the fire point of most other ignition resistant dielectric fluids in use today.
In laboratory and full-scale ignition tests, SHRIPARTH FR3 fluid has demonstrated greater fire resistance than other dielectric fluid types. Based on large-scale arc ignition testing, The probability of a pool fire evolving from SHRIPARTH FR3 fluid was so low that heat release rate need not be determined.
Based on large-scale arc ignition and hot metal ignition tests, SHRIPARTH FR3 fluid as an equivalent safeguard to space separation, fire barriers, and fire suppression systems for most installations.

Applications :

Power Transformers:

Ideal for distribution and power transformers in utilities, renewable energy systems, and industrial applications.

Retro fill Project s:

Suitable for replacing mineral oil in existing transformers to improve safety and extend equipment life.

Renewable Energy Systems:

Used in transformers for solar, wind, and other renewable energy projects, supporting sustainable power generation.

Critical Infrastructure :

Preferred for transformers in hospitals, data centers, and other essential facilities due to its high fire safety.
