ENVIROTEMP® FR3 FLUID

Envirotemp® FR3 fluid is a Fire Resistant Natural Ester dielectric coolant specifically formulated for use in distribution and power transformers where its unique environmental, fire safety, chemical, and electrical properties are advantageous. Envirotemp FR3 fluid is formulated from edible vegetable oils and food grade performance enhancing additives. It does not contain any petroleum, halogens, silicones, or any other questionable material.

Envirotemp FR3 fluid has an exceptionally high fire point of 360°C and flash point of 330°C. It has the highest ignition resistance of less-flammable fluids currently available. It is referred to as a High Fire Point or “Less-Flammable” fluid, and is Listed as a Less- Flammable Dielectric Liquid by FM Global (FM) and Underwriters Laboratories® (UL) for use in complying with the National Electric Code® (NEC) and insurance requirements.

Because of its excellent environmental, fire safety, and performance characteristics, applications for Envirotemp FR3 fluid have expanded into a variety of other equipment, including power transformers, voltage regulators, sectionalizing switches, transformer rectifiers, electromagnets, and voltage supply circuits for luminaries. The fluid is also used in retrofill applications for transformers and other fluid-filled distribution and power equipment.

Envirotemp FR3 fluid is compatible with standard transformer insulating materials, components and with fluid processing equipment and procedures. It 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. Excellent performance has been confirmed in more than 10,000 field installations since 1998. Envirotemp FR3 fluid is not listed as hazardous by the EPA, OSHA, or the Department of Transportation (DOT).

Advantages of retrofilling with Envirotemp FR3 fluid:

1. High dielectric strength
2. Dielectric constant very close to kraft paper insulation
3. Excellent lubricity
4. Excellent material compatibility
5. A coefficient of expansion similar to conventional transformer oil
6. Acts as a drying agent for transformer insulation that has become wet from aging, which helps extend the useful life of the transformer insulation system

Spills Happen – How to clean FR3 oil without harming painted parts or transformer insulation

Under normal operating conditions, solvents are needed to clean oil that spills over the transformer’s cover.Ecolink Inc has partnered with Cooper Power Systems to develop an effective and safe solution to clean and maintain transformers filled with Envirotemp FR3. S-34 NG is a Cooper Power Systems approved cleaner that safely and cost-effectively cleans transformers without harming painted parts or transformer insulation. S-34NG is SCAQMD compliant with 25 gm/l of VOC content and guaranteed to remove: Envirotemp FR3, transformer oils, FR3 oil, biodegradable hydraulic fluid, fire resistant hydraulic fluid, also known as Cooper FR3.
