Advantages
♦ Better viscosity-temperature and low temperature performance meeting application requirements of wider temperature range having better fluidity and pumping performance in low temperature condition
♦ Good thermal stability strong anti-oxidation reducing formation of various harmful oxides prolonging service life of oil
♦ Better oil-water separation ability meeting application requirements of severer operating mode reducing oil consumption
♦ Better anti-corrosion anti-rust and anti-foaming performance effectively inhibiting occurrence of corrosion and wear on parts providing better protection for equipment
♦ Perfect carrying ability ensuring smooth operation of heavy duty gears reducing scratch of gear surface effectively reducing operation noise
Applications
♦ Suitable for gears of various severe operating modes especially for heavy duty industrial gears requiring higher low temperature fluidity and water separation performance in such industries as mining metallurgy cement and so on
♦ Applied temperature range: -20ºC~120ºC possibly reaching 130ºC in short time
