Envirotemp™ 200 ester dielectric fluids

Envirotemp™ 200 fluid synthetic ester provides increased fire safety and improved performance

Envirotemp™ 200 fluid is a less flammable, synthetic ester-based dielectric liquid ideally suited for use in free-breathing transformers (both new and retrofill). It offers increased fire safety, greater environmental protection, high temperature performance and superior moisture tolerance.

Envirotemp 200 fluid has a high fire point (>300°C), and is classified as a K-class liquid (to IEC 61100/61039). Envirotemp 200 fluid has a flawless fire safety record, and enables reduced fire mitigation requirements when applied within a less-flammable fluid filled transformer.

Envirotemp 200 fluid is an environmentally superior alternative to mineral oil and silicone because it is classified as readily biodegradable (OECD 301) and non-hazardous in water and soil.

Envirotemp 200 fluid is a robust fluid that provides long-term stability even when exposed to extreme temperature variations. It also possesses excellent oxygen stability allowing it to be used in free breathing electrical equipment.

Envirotemp 200 fluid is relatively moisture tolerant and can absorb significantly more water than mineral oil before reaching saturation, while maintaining its dielectric strength. This interaction with water keeps the cellulose paper drier, slowing the aging rate of the solid insulation system. See IEEE C57.154™ Standard for the Design, Testing, and Application of Liquid-Immersed Distribution, Power, and Regulating Transformers Using High-Temperature Insulation Systems and Operating at Elevated Temperature.

Envirotemp 200 fluid has been thoroughly evaluated, and conforms to IEC 61099 “Specifications for Unused Synthetic Organic Esters for Electrical Purposes”.
