Biotransol HF is a natural ester based dielectric fluid based on renewable vegetable oils. The fluid is readily biodegradable as per US EPA OECD 301B, environmentally friendly and non–toxic to aquatic life. The product is certified for its electrical and chemical properties by CPRI, a reputed laboratory in India for dielectric fluid testing. It is also tested & certified at the reputed laboratories of Intertek for its biodegradability & absence of aquatic toxicity.

Designed to have superior properties as compared to conventional mineral based oils, Biotransol HF is classified under K class based on its high flash and fire point. These characteristics make Biotransol HF the ideal choice for applications requiring high fire safety and environmental protection in case of accidents or spillages.

With over 40 years in the business of designing dielectric fluids for Transformers, Savita has crafted Biotransol, to not only protect the environment but also significantly increase the life and performance of your transformer. Biotransol is your ideal dielectric fluid in applications requiring higher levels of efficiency, safety and environmental consciousness.

Efficient

  • Faster moisture extraction from paper insulation while maintaining BDV, thereby increasing performance and extending life of your transformer.
  • Slows ageing of transformer by enhancing life of solid insulation material.
  • Transformer load can be enhanced as a result of diminished paper ageing.
  • Reduces maintenance time and cost.
  • Less consumption of fluid relative to conventional oils.
  • Lower insurance premiums as a result of superior safety properties.
  • Lowers cost of clean-up and impact in case of accidental spillages.
  • Delays asset replacement and capex by prolonging the life of an aged transformer after Retrofil.

Safe

  • With a high Fire and Flash Point (>320°C, > 300°C), Biotransol significantly reduces risk of ignition and fire in case of accident.
  • Enhances safety for workers during installation, maintenance and condition monitoring.
  • Minimum damage in the event of spillage, as a result of its biodegradable nature.

Eco-Friendly

  • Designed from entirely renewable sources.
  • Reduces carbon footprint by being completely biodegradable.
  • Non-toxic and eco-friendly to the environment and aquatic life.
