R-Temp fluid, manufactured by Cooper Power Systems under
strict quality control for optimum transformer cooling
characteristics, has a higher fire point and higher
dielectric strength than mineral oil. The special formulation
is less-flammable as defined by the National Electric
Code (NEC) and National Electric Safety Code (NESC).
Since its introduction in 1975, over 90,000 R-Temp fluid-filled
transformers have been installed, approaching one million
unit years of service. The fire safety record is flawless.
R-Temp fluid is classified by Underwriters Laboratories®
and approved by Factory Mutual for use in indoor or
outdoor installations.
Envirotemp
200 Fire-Resistant Fluid
Envirotemp 200 fluid is a fire-resistant
dielectric coolant developed for applications requiring
high performance under extreme temperature conditions.
Its unique formulation provides very low freezing and
melting points. It is also a low viscosity fluid with
excellent dielectric, thermal and mechanical properties.
These properties make it particularly well suited for
forced liquid cooling operations such as in traction
transformers.
Envirotemp
FR3 Fire-Resistant Fluid
Envirotemp® FR3 Fluid, available in
Envirotran Transformers, is a natural ester-based fluid
formulated from a renewable natural resource -- seeds.
The base oils from the seeds are blended with food grade
performance enhancing additives to produce a fluid that
has exeptional fire-resistant properties and favorable
environmental attributes.
Envirotemp FR3 Fluid is classified by Underwriters Laboratories
and approved by Factory Mutual for use in indoor or
outdoor installations. It has an even higher fire point
than R-Temp fluid, for an even greater margin of fire
safety.
Plus, Envirotemp FR3 fluid is readily
biodegradeable and is non-bioaccumulating. Because it
is a seed-oil based fluid it can be differentiated from
mineral oil regulation per the Edible Oil Regulatory
Reform Act: Public Law 104-55. FM Approved Transformers
can be filled with R-Temp fire-resistant dielectric
coolant, which has a flawless fire safety record in
over 90,000 installations since 1975, or they can be
filled with Envirotemp FR3, a new even higher fire point,
edible seed oil-based fluid that is readily biodegradable,
non-toxic and performs even better. FM Approved Transformers
filled with Envirotemp FR3 fluid are sold under the
trade name Envirotran.
