FR3
Since 2005, Brandon & Clark has offered their customers the option to fill & retro-fill their electrical equipment with an environmentally friendly and EPA approved fluid called FR3®. Envirotemp FR3® fluid is made from food grade seed oils and food grade performance enhancing additives, which makes it completely biodegradable. FR3® fluid can help to extend the life of your transformers insulation and improves the transformers fire resistancy, through higher flash and fire points.
