Midel en 1204 Natural Ester Transformer Fluid
Midel en 1204 Natural Ester Transformer Fluid
MIDEL eN 1204 is an excellent dielectric fluid. It has a high fire point, making it demonstrably safer than mineral oil and is one of the most environmentally friendly dielectric fluids available.
Not only is MIDEL eN 1204 manufactured using renewable vegetable oil (rapeseed), it is also non-toxic and readily biodegradable. In addition, MIDEL eN 1204 offers superior moisture tolerance and has the potential to increase the lifetime of cellulose based solid insulation, which in turn can extend transformer life.
Natural Ester Transformer Fluid Advantages
With a pour point of -31°C (much lower than soya-based ester fluids), MIDEL eN 1204 is the premier natural ester transformer fluid. Made from sustainable rapeseed oil, it is readily biodegradable, non-toxic and is FM Global (Factory Mutual) and UL (Underwriters Laboratories) approved.

Why use MIDEL eN 1204 Natural Ester Fluid?
INCREASED FIRE SAFETY
MIDEL eN 1204 has a high fire point, significantly increasing the fire safety of your transformers and reducing the need for fire protection equipment.
100% fire safety record
High fire point (>300°C)
K class classification: less flammable fluid
Designed for indoor and outdoor installations
GREATER ENVIRONMENTAL PROTECTION
MIDEL eN 1204 is sustainably sourced and readily biodegradable, avoiding environmental damage should leakage occur and enabling reductions in containment measures.
Renewable vegetable oil
Lower carbon footprint than mineral oil
Readily biodegradable
Non-toxic
No corrosive sulphur
IDEAL SOLUTION FOR COLD CLIMATE
MIDEL 7131 has an extremely low pour point of -56˚C, making it a highly effective solution in colder climates.
Allows for compact transformer design
Permits greater flexibility and temporary overload resilience
SUPERIOR MOISTURE TOLERANCE
MIDEL eN 1204 has a high moisture tolerance. This characteristic enables the extension of cellulose insulation life.
Absorbs large amounts of moisture with no reduction of breakdown voltage (up to 300ppm)
High saturation limit (1100ppm @20˚C) making precipitation of free water virtually impossible
ASSET LIFE EXTENSION
MIDEL eN 1204 offers the ability to safely increase transformer loading or reduce transformer size. It is currently used in a wide range of transformer applications and is ideal for non free-breathing transformers located indoors or outside.
Slower rate of cellulose ageing than mineral oil
Longer cellulose lifetime at standard temperatures
Option to run at a higher temperature, for a standard lifetime
Provides a higher power output, without the need for high temperature insulation
