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”, and “non-propagating” fluid. SHRIPARTH FR3 fluid is Approved4 by FM Global and Classified5 by Underwriters Laboratories as a Less-Flammable Dielectric Liquid for use in complying with the National Electric Code6 (NEC) and insurance listing requirements7.
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, see Cargill document S900-20-1, SHRIPARTH FR3 Fluid Storage and Handling Guide for additional information.

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, FM Global concluded that the probability of a pool fire evolving from SHRIPARTH FR3 fluid was so low that heat release rate need not be determined or considered for FM Global approval.
Based on large-scale arc ignition and hot metal ignition tests, FM Global recognizes SHRIPARTH FR3 fluid as an equivalent safeguard to space separation, fire barriers, and fire suppression systems for most installations.
FM Global recognizes SHRIPARTH FR3 fluid as a component of Approved transformers per FM Global Standard 3990. When used in transformers containing 10,000 gallons of fluid or less, transformers separation distance to buildings and other equipment may be up to 1/10th the distance required for mineral oil filled transformers, without fire walls or deluge systems.

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.

Benefits of Using FR3 Oil

Environmental Responsibility : Reduces carbon footprint and aligns with global sustainability goals.
Cost Savings : Longer transformer life and reduced maintenance lower total ownership costs.
Regulatory Compliance: Meets or exceeds IEC, IEEE, and ASTM standards.
