The world’s first regenerated ester transformer fluid

Circularity in Action

MIDEL Regen is derived from in-service synthetic ester fluid which would otherwise be scheduled for disposal. It delivers the same MIDEL benefits of superior fire safety, environmental protection and improved transformer performance.

Since the 1970s MIDEL synthetic ester transformer fluid has been used in millions of assets worldwide, displacing mineral oil and PCBs with a safer, greener alternative.

We have used our 45+ years experience in developing esters to regenerate used MIDEL 7131 into MIDEL Regen, so it can be redeployed into the power industry.

This reinforces the growing adoption of, and preference for, MIDEL 7131. That the liquid can be regenerated at the end of its useful life gives owner/operators the added peace of mind of having selected the most sustainable insulating liquid for their transformer fleets.

A K-Class, biodegradable insulating fluid manufactured from regenerated synthetic ester liquids, reclaimed from end of life transformers.

The superior oxidation resistance over natural esters is what enables end of life synthetic ester to be regenerated into MIDEL Regen.

This can take place as assets are being decommissioned or at the end of the fluid’s initial useful life. Using MIDEL Regen helps to make transformers even greener while also delivering:

– INCREASED FIRE SAFETY –
– GREATER ENVIRONMENTAL PROTECTION –
– IDEAL FOR TRANSFORMERS IN COLD CLIMATES –
– EXTENDS TRANSFORMER LIFE –
– SYNTHETIC ESTER ADVANTAGES –
– ENABLES INNOVATION –

MIDEL esters are positive contributors towards a number of UNSDGs through the displacement of harmful PCBs, mineral oil and SF6 as a fire safe, environmentally friendly alternative. As a regenerated fluid, MIDEL Regen also allows transformer owner/operators to avoid incinerating or disposing of end of life synthetic ester from their ageing transformer fleets.

In partnership with transformer OEMs and Utility providers, MIDEL fluids are also widely accepted as enabling more sustainable substations and power networks, for example in renewables, rail, distribution and power applications. As Utility providers implement grid hardening and climate resiliency programmes, MIDEL is also widely specified as policy and in large power resiliency transformers.

M&I Materials is committed to maximising its sustainability contributions both as an Ecovadis Silver organisation and through its products in respect to the UN Sustainable Development Goals.
