MIDEL eN 1215

Manufactured and available in the USA, MIDEL eN 1215 is a versatile, fire-safe transformer fluid. Made from a renewable soya source, it outperforms mineral oil and delivers real benefits to utilities and transformer manufacturers.

Fire safe fluid

Safety is critical. MIDEL eN 1215 has a 100% fire safety record for unrivalled risk mitigation. Certified as K-class, its low flammability and high fire point (>300ºC) makes it the safest choice of transformer fluid.

With the reassurance of a protected network comes the benefit of cost savings. Reduced need for fire suppression and containment systems offer tangible financial advantages.

Biodegradable

The renewable raw material base of MIDEL eN 1215 gives it a lower carbon footprint compared to mineral oil. Fully biodegradable, it is less harmful to soil, and is non-water hazardous in case of spillage.

Moisture tolerant

Compared to mineral oil, MIDEL eN 1215 has the potential to absorb substantially more water without affecting dielectric properties.

Extended asset lifetime

MIDEL eN 1215 is scientifically proven to prolong the ageing of cellulose insulation at standard temperatures.

Do you need to run your transformer harder? Or for longer than originally intended?

Do you need to use smaller, lighter transformers?

The versatility of MIDEL eN 1215 guarantees performance over a standard lifetime, even when power output or temperature is increased.

MIDEL 7131

MIDEL 7131 is a versatile synthetic dielectric fluid. It’s used in a wide range of transformer applications, including sealed and free-breathing designs which delivers cost savings and social responsibility.

First produced in the 1970s, MIDEL 7131 meets the need for a safer alternative to mineral oil. Its success is proven with its use up to 400kV and in thousands of transformer applications across the world.

Ultimate protection

Superior fire safety is vital, especially in demanding or high-density urban locations.

MIDEL 7131 has an unrivalled safety record. The combination of a high fire point (>300ºC) and low net calorific value (<32 MJ/kg) gives it K3-class status, guaranteeing maximum safety.

Increased safety brings reduced project costs. Costs for safeguarding against the risk of fire can be significantly moderated when using a fire-safe ester fluid.

Safe for the environment

Far safer than mineral oil, MIDEL 7131 is readily biodegradable (OECD 301). A non-toxic fluid, if leaked or spilled it is non-hazardous in water and soil, and safe to marine life.

Oxidation and low temperature stability

The high oxidation stability of MIDEL 7131 means the fluid can be safely used in breathing transformers. The extremely low pour point of -56C, makes it a highly effective solution for colder climate installations.

Enables innovation

Designers have been able to develop a wide range innovate solutions around the properties of MIDEL 7131, including Bio-Slim wind turbine transformers, sub-sea applications, cable connectors, mobile flexible transformers and power transformers withy waste heat utilization.

Where is MIDEL 7131 used?

Optimized transformers

The high moisture tolerance of MIDEL 7131 ester fluid keeps transformers performing. Its water absorption rate avoids the need for unnecessary maintenance servicing and refills, keeping costs down and power sustained.

Third-party testing proves MIDEL 7131 contributes to extended cellulose life. Insulation lasts longer at standard and higher temperatures, enabling optimized transformer performance.

MIDEL eN 1204

MIDEL eN 1204 is a natural ester transformer fluid, now available in the USA. Made from renewable canola oil, it has a high rate of biodegradation. With superior risk mitigation and dielectric properties, it’s proven to outperform mineral oil.

100% fire safety

Taking operations to a safer place, MIDEL eN 1204 is a classified K2 liquid. Its high fire point ensures power continuity, protecting people and valuable assets. Where safety is paramount, MIDEL eN 1204 makes the grade.

Sustainable

There are times when fluids may spill or leak. Unlike Mineral and Silicone oils, eN 1204 is fully biodegradable and non-water hazardous.

Moisture tolerant

Compared to mineral oil, MIDEL eN 1204 has greater water absorption properties. Less moisture extends transformer performance and avoids costly downtime. Breakdown voltage is maintained (up to 300ppm moisture at 20ºC) and power networks sustained.

Asset extension

Cellulose is guaranteed to last longer with MIDEL eN 1204. Whether running at higher temperatures or through sustained use, transformer insulation life can be extended, ensuring profitable power performance.
