Envirotran Transformers

Envirotran™ transformers are specifically designed and manufactured to take advantage of the performance benefits of Envirotemp™ FR3™ fluid. Envirotran transformers are the industry’s first transformers to use an edible vegetable oil-based, high-fire-point dielectric coolant.

This technological and environmental design breakthrough is the result of years of research and development in dielectric fluids and their use in transformers. Confirmed with extensive laboratory and field testing, Envirotran transformers are safer for Earth and its inhabitants. They have exceptional performance characteristics, making them ideal for indoor or outdoor installations.

Environmentally Desirable

Envirotran transformers are friendlier to the environment. While traditional liquid-filled transformers use mineral or synthetic oils, Envirotran transformers use the revolutionary, vegetable oil-based, dielectric coolant, Envirotemp™ FR3™ fluid. Envirotemp™ FR3™ fluid is a unique dielectric coolant whose base oils come from a renewable natural resource—seeds. Specially formulated with performance-enhancing food-grade additives, this non-toxic, readily biodegradable insulating fluid is the first truly green fluid.

Unmatched Safety and Performance

Not only are they safer for the environment, Envirotran transformers are safer for the people and buildings they serve. Based on electrical fire code regulations and Nationally Recognized Testing Laboratory certifications, Envirotran transformers can be installed indoors and outdoors, adjacent to buildings, walkways or on roof tops, typically without additional fire safety requirements.

This additional margin of safety makes Envirotran transformers ideal for commercial or industrial complexes, office buildings, institutions and other fire safety sensitive applications.

Increased Electrical Power and Reduced Footprint

Following the determination of Envirotemp™ FR3™ fluid’s life extension properties, tests show that paper aged in Envirotemp™ FR3™ fluid takes 5-8 times longer to reach the same end-of-life points as paper aged in conventional transformer oil.

Rather than build a transformer with an insulation system lasting over 100 years, Cooper Power Systems has taken the next step in improved transformer performance. Cooper Power Systems now offers the option of specifying 75°C temperature rise in selected products. This provides the same electrical power as a standard 55° or 65°C rise, but with a reduced footprint and first cost. Users can also specify 55 - 75°C temperature rise, allowing for a 22% electrical power increase.

Higher Performance Lower Total Owning Cost

Envirotran transformers provide all the inherent advantages of liquid-filled transformers when compared to dry and cast resin types, including higher overload capacity, higher efficiencies, cooler and quieter operation, sealed construction, and longer life. Envirotran transformers also have a lower Total Life-Cycle Cost and Total Owning Cost. Liquid-filled transformers are typically lower in initial price and are less expensive to install than open dry-types with comparable ratings and features and are much lower when compared to cast resin types. They also require less room than comparable dry-type transformers.
