Envirotemp FR3, the ester-based dielectric coolant for distribution transformers, is a fire-resistant ester-based dielectric coolant for distribution transformers. Envirotemp FR3 is formulated from edible seed oils and food grade performance-enhancing additives. Envirotemp FR3, the ester-based dielectric coolant for distribution transformers, does not contain any petroleum, halogens, silicones – or any other questionable material. Envirotemp FR3 biodegrades quickly and thoroughly in soil and aquatic environments. Envirotemp FR3 tested non-toxic in aquatic toxicity tests. Envirotemp FR3 is tinted green to reflect its favourable environmental profile.

Envirotemp FR3, the ester-based dielectric coolant for distribution transformers, has an exceptionally high fire point of 360 C and flash point of 330 °C. Envirotemp FR3 has the highest ignition resistance of less flammable fluids currently available. Envirotemp FR3 is referred to as a High Fire Point or ‘less flammable’ fluid. Envirotemp FR3 is listed as a ‘less flammable dielectric’ by Factory Mutual and Underwriters Laboratories for use in complying with the National Electric Code (NEC) and insurance requirements.

Envirotemp FR3, the ester-based dielectric coolant for distribution transformers, is compatible with standard transformer insulating materials, components and with fluid processing equipment and procedures. Envirotemp FR3 demonstrates improved thermal characteristics with a viscosity closer to conventional transformer oil, superior dielectric strength in new and continued service applications, and excellent chemical stability over time.
