NYTRO BIO 300X is the result of years of intensive research. We are now able to offer a 100% renewable product with superior performance. A true innovation. 

A key advantage of this new fluid is that it offers exceptionally good cooling thanks to its ultra-low viscosity. The transformer's winding hot spot temperature can be significantly reduced. Initial studies show up to 10 degrees improvement compared to mineral oils that comply with IEC standard 60296 and around 20 degrees lower compared to ester liquids that comply with IEC standard 61099 or 62770. There is huge potential for thermal design optimization as well as improved over-loading capability. 

NYTRO BIO 300X is also the product that combines ready biodegradability with superior oxidation stability. Just like all the other Nynas products for the electrical industry, NYTRO BIO 300X is fully recyclable. 

NYTRO BIO 300X meets and exceeds the IEC 60296 specifications. 

This newest addition to our portfolio allows transformer OEM's and Utilities more flexibility in selecting the best suited fluid for a certain application.
