Envirotemp® FR3™ Dielectric FluidcargillFR3
Revolutionary. Reliable. Responsible

Because the benefits of Envirotemp® FR3™ Fluid are so extraordinary, it no longer makes sense to specify other  dielectric fluids.  FR3™ Fluid sets the new standard for environmental responsibility, ignition resistance, and extended transformer life.

ENVIRONMENTALLY RESPONSIBLE
 
 
FR3-Fluid-IV
A renewable resource consisting of 98.5% vegetable oil, FR3™ Fluid sets the new standard for environmental responsibility.  Not only is it biodegradable to 99% in just 21 days, it is covered by the Edible Oil Regulatory Act, and therefore eligible for current and future regulatory relief.
 
HIGHEST FIRE POINT OF ALL LESS-FLAMMABLE FLUIDS
With a fire point of 360C, FR3™ fluid has the highest fire point of all listed Less-Flammable fluids.  In fact, FM Global® concluded that the probability of a pool fire was so low, that heat release rate need not be determined or considered in determining the installation requirements of the fluid.
 
SIGNIFICANTLY EXTENDS TRANSFORMER LIFE
FR3™ Fluid extends the end of life points of insulation paper 5-8 times longer than paper aged in mineral oil.  FR3™ fluid 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.
 
 

PRODUCT QUICK LINKS

 

USES

  • Used in transformers and other fluid-filled distribution and power equipment.
  • Proven applications include new and retrofilled sectionalizing switches, and transformers with loadbreak accessories such as bay-o-net fusing, on-off switches, sectionalizing switches and Vacuum Fault Interruption protection devices.
  • Other applications include industrial electromagnets, klystron modulators, transformer/rectifier sets, power supplies for luminaries and heat transfer applications for testing equipment.

ENVIRONMENTAL BENEFITS

  • Formulated from edible vegetable oils and food grade performance enhancing additives.
     
  • Does not contain and petroleum, halogen, silicones or any other questionable material.
     
  • Quickly and thoroughly biodegrades in soil and aquatic environments.
     
  • The base oils in FR3™ Fluid come from renewable resources – commodity seeds – and are easily recyclable and reusable.
     
  • Envirotemp® FR3™ fluid does not require genetically altered vegetable oils.
     
  • Deemed “ultimately biodegradable” by the EPA.
     
  • In one of the most extremely sensitive acute toxicity tests, the Trout Fry Acute Toxicity test OECD 203, Envirotemp FR3 fluid out-performed other dielectric fluids by achieving a zero mortality rate throughout the entire test period.
     
  • Because Envirotemp® FR3™ Fluid is formulated form food grade oils and additives, it is not subject to Federal Regulation of Used Oils.  It is instead covered by the Edible Oil Regulatory Act, and therefore eligible for current and future regulatory relief.
     
  • Option of alternative spill response procedures, such as bioremediation, are now more viable.
     
  • Not listed as hazardous by EPA, OSHA or DOT.
     
  • Candidate for classification as “Environmentally Preferred Products”.
     
  • Hazardous Material Information System (HMIS) rating is 0 for both health and reactivity.
     
  • Not listed as a carcinogen by National Toxicology Program (NTP), International Agency for Research on Cancer (IARC) monographs and OSHA regulation.
     
  • Decomposition byproducts are limited to CO2 and H2O with a trace of CO depending on availability of oxygen and temperature.
     
  • Cannot produce PCDFs (Furans), PCDDs (Dioxins), nor silicates.
     
  • Well-suited as a replacement fluid for upgrading the safety margin of fluid-filled transformers from both an environmental and fire safety aspect.

FIRE SAFETY / TEMPERATURE RESISTANCE BENEFITS

  • High fire point of 360 and flash point of 330.
  • Highest ignition resistance of less-flammable fluids available.
  • Listed as a Less-Flammable Dielectric Fluid by FM Global® (FM) and Underwriters Laboratories® for use in complying with the National Electric Code® (NEC) and insurance requirements.
  • Greater fire resistance than other askarel substitutes.
  • FM Global® concluded that the probability of a pool fire was so low, that heat release rate need not be determined or considered in determining the installation requirements of the fluid.
  • Has the lowest gassing tendencies under electrical stress.
  • Superior resistance to coke and sludge formation when compared to conventional oil.  Doble Laboratories sludge-free life test resulted in no measurable sludge.

TRANSFORMER LIFE EXTENSION BENEFITS

  • Exceptional ability to draw out retained moisture and absorb water driven off by aging paper.
  • Chemically helps prevent paper molecules from severing when exposed to heat.
  • Significantly minimizes the rate of aging of transformer insulating paper.
  • Takes 5-8 times longer to reach end-of-life points as paper aged in conventional transformer oil.
  • In a retrofilling application, the residual transformer fluid that remains in the transformer typically will not reduce the fire point below the NEC minimum 300 C.  This is true even after full equilibrium has been achieved between the replacement fluid and the residual oil in the paper.
  • Fluid acts as a drying agent for transformer insulation that has become wet from aging, this property helps extend the useful life of the transformer insulation system.

OTHER FEATURES / BENEFITS

  • Viscosity is closer to conventional transformer oil.
  • FM Global® accepted for fluid filled transformers indoors, typically with sprinklers or vaults, with minimum clearance of just 36 inches.
  • Fully miscible with conventional transformer oil, High Molecular Weight Hydrocarbons (HMWH), and most askarel.
  • Does not cause foaming like silicone oil can under vacuum degassing.
  • Unlike silicone, FR3™ Fluid does not cause paint adhesion problems, nor form the silicates during switching that can lead to a severe reduction in dielectric strength.
  • Excellent loadbreak switching mechanism at temperatures above -10 C.
