Midel 7131 Retro Filling

Grosvenor Oil Services Limited has been appointed by M&I Materials as a Midel Service Partner (MSP), enabling us to carry out Retro Filling on customer transformers.

Retro filling is the process of replacing mineral oil insulating fluid in an existing transformer with MIDEL fluid. Doing so effectively upgrades the transformer while delivering other demonstrable benefits.

Reasons for retro filling with MIDEL:

Makes financial sense – get all the benefits of MIDEL without investing in a new transformer

Remove fire risk – the high fire point of MIDEL fluids eliminates the possibility of transformer fire, thereby protecting lives and property plus reinforcing business continuity

Avoid risk of environmental contamination – MIDEL fluids are readily biodegradable, unlike mineral oil which is both toxic and non-biodegradable. Using MIDEL reduces the risk of environmental damage to the environment in case of either minor leak or catastrophic failure of the transformer

Demonstrate Corporate Social Responsibility – retro filling your transformer with MIDEL shows a commitment to your employees, customers and environment without needing to invest in a new transformer

Recommended by insurance companies – insurance companies, such as FM Global, acknowledge that all transformers are at risk of failure which can result in fire or environmental damage, and can adversely affect business continuity. They regularly advise their clients to retro fill mineral oil transformers with MIDEL fluids

Increase transformer life, delay transformer replacement – using MIDEL will extend transformer life and delay investment in a new replacement transformer. The superior water tolerance properties of MIDEL significantly increase the life of solid insulation, thereby extending the life of the transformer. MIDEL has also been successfully used to enable wet transformers to be brought back into service

Cut operating expenses – maintenance of mineral oil transformers can be costly – consider oil filtration operations and maintenance of fire suppression systems. Using MIDEL can help reduce maintenance OpEx requirements. MIDEL is also much more tolerant of moisture ingress than mineral oil. For areas prone to wet conditions, retro filling transformers with MIDEL fluids can lead to increased asset reliability

Reduce substation footprint – FM Global guidelines mean MIDEL transformers require significantly less space compared to mineral oil transformers. Using MIDEL enables more than one transformer to be installed in the same footprint required for mineral oil – a compelling solution if new capacity is needed in an existing substation
