Deep refined base oil is used, and additives such as anti-oxidant, anti-rust, anti-foam, and anti-emulsification additives are added and prepared by scientific formula.Outstanding thermal oxidation stability, long-term use will not produce harmful sediment.Excellent anti-emulsification, can quickly separate from the contacted water and maintain sufficient oil film strength.
Applicable to the lubrication and sealing of mechanical equipment such as electric power, ships and other industrial steam turbines, hydraulic turbines, and generator bearings. It can also be used in ordinary hydraulic systems.
