Envirotemp FR3 fluid is a bio-based, sustainable, natural ester dielectric
coolant for use in distribution and power class transformers where its
unique fire safety, environmental, electrical, and chemical properties are
advantageous.  Envirotemp FR3 fluid is formulated from seed oils and performance enhancing additives. It quickly and thoroughly biodegrades1 in the environment. The fluid is non-toxic in acute aquatic2 and oral toxicity tests3.  Envirotemp 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.
