Gomero Complements the Use of Midel 7131

More and more grid owners are today choosing more environmentally friendly alternatives for their power transformers. Midel 7131 is a synthetic ester fluid used to cool transformers and offers several important advantages compared to traditional mineral oil.

Significantly Reduces Fire Risk 
Midel 7131 has a much higher flash point than mineral oil, making it considerably safer to use. This means less risk of fire at power stations and substations. You need less fire protection such as bund walls or complex underground tanks, which saves both money and space. The transformers can also be placed closer together, reducing the total footprint of the installation.

Provides Better Performance 
Power transformers are critical infrastructure where outages are very costly. Midel 7131 conducts heat away more efficiently than mineral oil, which improves equipment performance and reliability. This provides higher productivity and fewer costly downtime periods. Less volume is required, meaning both the transformer and oil catch pit can be made smaller.

Extends Equipment Lifespan 
Midel 7131 has excellent insulating properties that reduce the risk of electrical failures and faults. This protects your equipment better than traditional mineral oil and provides longer equipment lifespan with less need for maintenance and repairs.

Better Environmental Protection 
Midel 7131 breaks down naturally in the environment, unlike mineral oil which is toxic. In case of spills or leakage, environmental damage is much less, helping you avoid costly environmental fees and remediation efforts that follow mineral oil releases.

Regulations That Favour Environmentally Friendly Alternatives 
The EU's stricter environmental requirements and ecodesign regulations for transformers favour the use of biodegradable fluids like Midel 7131. This means simpler regulatory compliance and potentially lower construction costs through reduced requirements for protective structures around the transformers.

Even though Midel 7131 is more environmentally friendly than mineral oil, it's important to handle all fluids correctly to completely protect the environment. Gomero's measuring cell detects leakage early and has very high accuracy. It is third-party validated and can detect both mineral oil and ester fluids down to 1PPM - regardless of which type of transformer fluid you use.

• Early detection of spills and leakage
• Protection of the environment from industrial emissions
• Long-term traceability and transparency
• Secure regulatory compliance

Midel 7131 offers significant advantages compared to traditional mineral oil: reduces fire risk, improves performance, extends equipment lifespan, and better protects the environment.

Combined with Gomero's measuring cell, you get a complete system that both optimises your power transformers and ensures environmental protection with full traceability.
