The MIDEL Range

MIDEL eN 1215 is a versatile, fire-safe ester transformer fluid made from renewable soybean crops. Environmentally safer than mineral oil, MIDEL eN 1215 has a pour point of -18°C and delivers excellent performance in non-free breathing transformers in temperate climates. Reliable performance from an ester fluid with sound sustainability credentials.

MIDEL eN 1204 is a superior natural ester transformer fluid, made from renewable rapeseed/canola oil. It delivers very effective cold weather performance (-31°C pour point) and has better oxidation characteristics than soya-based natural ester fluid. The right solution for non free-breathing transformers in cooler climates.

MIDEL 7131 is the world’s leading biodegradable synthetic transformer fluid. Proven to 433kV and with a pour point of -56°C, this is a robust fluid for mainstream and the most demanding environments – including extremes of heat or cold, sub-sea, underground, offshore wind and traction applications – for both sealed and free-breathing units.
