IsoTec SE 300 Synthethic Transformer Oils
Synthetic Ester dielectric fluid sets a new benchmark for transformer performance and sustainability. Proven in demanding grid and industrial applications, it offers superior thermal stability, exceptional moisture tolerance, and enhanced fire safety compared to conventional mineral oils. Its long service life and biodegradable composition reduce maintenance costs and environmental impact, delivering reliable, efficient power for utilities and businesses committed to cleaner energy.
Why IsoTec SE 300?
POWER NETWORKS YOU CAN RELY ON- SAFE, SMARTER & STRONGER
IsoTec SE 300 is a high-performance synthetic ester transformer fluid designed to deliver maximum safety, reliability, and environmental responsibility. It provides excellent fire protection, insulation support, and operational efficiency for modern transformers. With a fire point above 317 °C and self-extinguishing properties, IsoTec SE 300 significantly reduces fire risk compared to mineral oils. Its low pour point of –56 °C ensures reliable performance in extreme cold, while its moisture tolerance of up to 2700 ppm protects insulation, slows aging, and extends transformer life. Fully biodegradable and non-toxic, it also minimizes environmental impact, making it an ideal choice for sustainable power systems.
High-Performance Ester Oil for Your transformer With Maximum Safety
IsoTec SE 300 is a K3 transformer fluid that replaces mineral oils. It provides excellent fire protection, strong cold resistance, and extends the service life of your equipment.
Superior Fire Safety and Risk Reduction
With a high flash point exceeding 317 °C and self-extinguishing properties, IsoTec SE 300 provides a superior level of fire safety compared to conventional transformer fluids such as mineral oil. These characteristics significantly reduce the risk of transformer fires, protecting not only the equipment itself but also surrounding infrastructure and personnel.
By greatly minimizing the likelihood of a fire incident, IsoTec SE 300 helps operators comply with strict safety regulations and improve overall system reliability. In many cases, the exceptional fire safety performance of this fluid can reduce or even eliminate the need for additional fire protection measures, such as fire barriers, suppression systems, or special containment structures.
This translates into lower operational risks and considerable cost savings over the lifetime of the transformer, while also simplifying the design and installation of transformer systems in sensitive or space-limited environments, such as urban substations, industrial facilities, or offshore platforms.
Biodegradable and Non-Toxic – Safe for Sensitive Environments
IsoTec SE 300 is readily biodegradable and non-toxic, making it an environmentally responsible choice for transformer operations. In the unlikely event of a leak or spill, the fluid breaks down naturally and quickly, ensuring a minimal and short-term impact on the surrounding environment. Unlike conventional mineral oils, which can cause long-lasting soil and water contamination, IsoTec SE 300 degrades safely without leaving harmful residues.
This high level of environmental compatibility provides a significant advantage for utilities and operators, particularly when transformers are installed in environmentally sensitive locations, such as near rivers, lakes, wetlands, nature reserves, or densely populated urban areas. Because the fluid poses no significant threat to ecosystems or human health, it helps to simplify containment measures and reduce the need for costly protective infrastructure, such as retention basins or complex drainage systems.
Moreover, the use of IsoTec SE 300 makes it easier to comply with strict environmental regulations and sustainability goals, supporting companies in achieving greener operations and meeting both corporate and governmental environmental standards. By choosing IsoTec SE 300, operators demonstrate a clear commitment to protecting natural resources while maintaining high levels of transformer performance and safety.
Engineered for Harsh Climates and Long-Term Durability
The extremely low pour point of –56 °C ensures that IsoTec SE 300 maintains outstanding fluidity and performance even under the harshest cold climate conditions. This makes it the ideal choice for transformer installations in arctic, alpine, or other sub-zero environments, where traditional mineral oils often become too viscous to operate effectively. As a result, transformers filled with IsoTec SE 300 continue to run smoothly and reliably, even during extreme winter conditions, ensuring uninterrupted power supply and system stability.
In addition to its cold-weather resilience, IsoTec SE 300 offers exceptional moisture tolerance, with the capability to handle water levels of up to 2700 ppm without a negative impact on performance. This property plays a critical role in protecting cellulose insulation inside the transformer. By effectively absorbing and managing moisture, IsoTec SE 300 slows down the natural aging process of insulation materials, thereby prolonging transformer life and reducing the frequency of costly maintenance or replacements.
This combination of cold-climate reliability and long-term insulation protection makes IsoTec SE 300 an ideal solution for transformers operating in demanding environments, ensuring both operational continuity and asset longevity.
