IsoTec NE 350 – Natural Ester Fluid for Safety and Sustainability
Protecting people, assets, and the environment.
Natural ester dielectric fluids have demonstrated their advantages—from early validation trials to global adoption in power and distribution transformers. They deliver a safer, more reliable, and higher-performing solution compared to traditional insulating liquids, while also ensuring cost efficiency and environmental benefits that help provide dependable energy to communities worldwide.
Why IsoTec NE 350?
IsoTec NE 350 is a K2-class, bio-sourced dielectric fluid that combines safety, sustainability, and reliability. With a high fire point above 350 °C and a pour point of −31 °C, it enhances transformer fire safety while ensuring dependable performance in colder climates. Biodegradable and non-hazardous, it supports environmentally responsible operations and can reduce containment and fire protection requirements. Its excellent moisture tolerance helps protect solid insulation, contributing to longer transformer life and reduced operating costs.
Power Networks That Work Harder and Smarter
IsoTec NE 350 offers exceptional fire safety, with a high flash and fire point for maximum protection. Transformers using the natural ester fluid can safely operate up to 20 °C hotter than those filled with mineral oil. Synthetic ester fluid helps meet fluctuating power demands without accelerating aging, potentially extending transformer life.
Unique chemical Properties - Moisture Tolerance
Compared to conventional mineral oils, IsoTec NE 350 natural ester can absorb more moisture without compromising dielectric strength. Its high saturation point and unique chemistry help protect solid insulation, slow aging, and maintain reliable operation—enhancing transformer reliability over time.
Better for the Environment
By choosing a biodegradable natural ester fluid, you support your company’s sustainability goals, protect the environments where your transformers operate, and reduce reliance on conventional oils.
As a biodegradable transformer fluid with outstanding performance, natural ester minimizes environmental impact far beyond what mineral oil can achieve. Its superior eco-friendly properties help you meet sustainability targets while potentially reducing costs—all without compromising on performance.
Maximizing financial benefits through optimized transformer fluid
Choosing a natural ester fluid over mineral oil provides multiple business advantages. It enhances grid reliability and resilience while reducing environmental impact.
In addition, natural ester fluid optimizes transformer performance, allowing higher operating temperatures and increased load capacity without accelerating insulation aging. This leads to fewer outages, lower maintenance requirements, and extended transformer life—all of which contribute to significant cost savings over the lifetime of the equipment.
By deploying natural ester fluid across your transformer fleet, you can maximize efficiency, cut operational costs, and still deliver safe and reliable service to your communities.
