NATURAL ESTER FLUIDS / ENVIROTEMP® FR3™


Envirotemp® FR3® is a patented, biodegradable, seed-based dielectric fluid designed by Cooper Power Systems. Formulated from edible vegetable oils, FR3 fluid has been proven to add value to new and retrofilled power equipment.



MAIN BENEFITS OF ENVIROTEMP® FR3® DIELECTRIC FLUID:

Environmental Biodegradability
In conjunction with recognized testing organizations, the U.S. Environmental Protection Agency (EPA) created the Environmental Technology Verification (ETV) Program to further environmental protection by accelerating the acceptance and use of innovative, improved and more cost-effective technologies. By objectively and systematically documenting the performance of commercial-ready environmental technologies, the ETV Program intends to assist and inform those individuals in need of credible data before utilizing a new technology.

The EPA's report on its ETV Program tests and results on FR3 can be downloaded here in Adobe Acrobat (PDF) format:

Fire Safety
This benefit comes from having an exceptionally high fire point (360°C). Because of this, FR3 is listed as a Less-Flammable Dielectric Liquid by Factory Mutual and Underwriters Laboratories for use in complying with the National Electric Code® (NEC) and insurance requirements.
