ENVIROTEMP FR3™ FLUID - nttworldwide.com

1 DESCRIPTIONE nvirotemp FR3 FLUID is a Fire ResistantNatural Ester based dielectric coolant specifically for-mulated for use in distribution transformers where itsunique environmental, fire safety, chemical, and elec-trical properties are FR3 FLUID is formulated from edibleseed oils and food grade performance enhancingadditives. It does not contain any petroleum, halo-gens, silicones or any other questionable material. Itquickly and thoroughly biodegrades in both soil andaquatic environments. The FLUID tested non-toxic inaquatic toxicity tests.

2 It is tinted green to reflect itsfavorable environmental profile. ENVIROTEMP FR3 FLUID has an exceptionally highfire point of 360 C and flash point of 330 C. It has thehighest ignition resistance of less-flammable fluidscurrently available. It is referred to as a High FirePoint or "Less-Flammable" FLUID , and is Listed as aLess-Flammable Dielectric Liquid by Factory Mutualand Underwriters Laboratories for use in complyingwith the National Electric Code (NEC ) and insur-ance FR3 FLUID is compatible with standardtransformer insulating materials, components and withfluid processing equipment and procedures.

3 It demon-strates improved thermal characteristics with a vis-cosity closer to conventional transformer oil, superiordielectric strength in new and continued service appli-cations, and excellent chemical stability over time. Because of it excellent environmental, fire safetyand performance characteristics applications forEnvirotemp FR3 FLUID have expanded into a variety ofother equipment, including sectionalizing switches,transformer rectifiers, electromagnets, and voltagesupply circuits for luminaries. Other potential applica-tions under study include voltage regulators, high volt-age cables, and power substations.

4 The FLUID is alsoused in retrofill applications for other FLUID filled distri-bution equipment.

6 These properties are subject to change without CPS Dielectric Fluids Products for recommended accep-tance values. Ask for ENVIROTEMP FR3 FLUID Specification Guideline,Bulletin unique chemical structure of EnvirotempFR3 FLUID provides superior performance characteris-tics. The FLUID maintains its dielectric strength muchbetter than other dielectric fluids when used as aload-break switch medium, and has the lowestgassing tendencies under electrical stress. Its cool-ing performance is superior to other less-flammablefluids. It has lower viscosity at operating tempera-tures than other less-flammable fluids.

7 The fluidexhibited no measurable change in viscosity overexhaustive testing cycles. It has superior resistanceto coke and sludge formation when compared toconventional transformer oil. Under the same accel-erated coking tests, ENVIROTEMP FR3 FLUID producedless than 1/20 of carbonaceous coke than that pro-duced in mineral oil. Doble Laboratories sludge-freelife test resulted in no measurable Stability TestEnvirotemp FR3 FLUID has an exceptional abilityto draw out retained moisture and absorb water driv-en off by aging paper. It also chemically helps pre-vent the paper molecules from severing whenexposed to heat.

8 These attributes enable the fluidto significantly minimize the rate of aging of trans-former insulating paper. Tests have shown thatpaper aged in ENVIROTEMP FR3 FLUID takes 5-8 timeslonger to reach the same end-of-life points as paperaged in conventional transformer following chart shows a comparison of thetime to reach insulation end-of-life for thermallyupgraded Kraft paper aged in conventional trans-former oil and ENVIROTEMP FR3 FLUID .

9 Tobe conservative, extrapolation was not SAFETYE nvirotemp FR3 FLUID has a fire point of 360 C,well above the NEC minimum of 300 C. Its flash point(330 C) is higher than the fire point of most other cur-rently available less-flammable fluids. EnvirotempFR3 FLUID is certified as a less-flammable dielectriccoolant by Factory Mutual and UnderwritersLaboratories in compliance with the listing require-ments of the NEC.
