EMI’s flagship product, EMRO 60HT, is a severely hydrotreated 60-viscosity naphthenic oil engineered for high-performance electrical insulation and thermal stability. Designed for demanding applications, EMRO 60HT delivers excellent dielectric strength, oxidation resistance, and long-term reliability in transformers and other oil-filled electrical equipment.
We also produce EMRO 60TO, a 60-viscosity naphthenic oil formulated for use as an insulating fluid in electrical transformers. EMRO 60TO exceeds the industry standard ASTM D3487, providing dependable insulating performance, equipment protection, and extended service life across a wide range of operating conditions.
Beyond our transformer oil offerings, EMI supplies high-quality naphthenic base oils in viscosities ranging from 60 to 600 to support a variety of industrial and specialty applications. With bulk storage capacity exceeding half a million gallons and dedicated blending tanks, we have the flexibility and capability to develop custom-blended base oil solutions tailored to your specific performance and formulation requirements.
EMRO 60HT
EMI’s proprietary insulating oil is engineered for high performance and long-term reliability in demanding electrical applications. Our EMRO 60HT formulation undergoes additional treatment and advanced refining processes to enhance purity, oxidation stability, and dielectric strength. This careful processing ensures consistent performance under elevated thermal and electrical stress. As a result, EMRO 60HT not only meets but is designed to exceed the requirements of the industry-standard specification ASTM D3487 for mineral insulating oils. This guarantees exceptional insulating properties, improved equipment protection, and extended service life for transformers and other oil-filled electrical apparatus.
