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.
