The world’s first regenerated ester transformer fluid
K-Class – Regenerated Synthetic Ester – Extends Asset Life
Shell MIDEL Regen is derived from in-service synthetic ester fluid which would otherwise be scheduled for disposal. It delivers the same Shell MIDEL benefits of superior fire safety and improved transformer performance.
The superior oxidation resistance over natural esters is what enables end of life synthetic ester to be regenerated into Shell MIDEL Regen. This can take place as assets are being decommissioned or at the end of the fluid’s initial useful life. Using Shell MIDEL Regen delivers:
- Increased fire safety
- Lower impact from accidental leaks
- Transformer life extension

Since the 1970s Shell MIDEL synthetic ester transformer fluid has been used in millions of assets worldwide as a fire-safe alternative to mineral oil and PCBs. With Shell MIDEL Regen, transformer owners and operators have the reassurance that the insulating fluid can be regenerated at the end of its useful life.
Shell MIDEL Regen meets the electrical and chemical performance parameters of IEC 61099, the standard for new synthetic ester transformer fluids.
