Maxtop anti-ammonia steam turbine oil (MTARTO) is developed by adding anti-oxygen, anti-rust, anti-foam and other additives to highly refined base oil. It is designed to provide lubrication and sealing solutions for compressors and steam turbine units with ammonia as the medium. Excellent wear resistance, suitable for most conventional working conditions. Low temperature fluidity, ensure low temperature starting performance. Effectively neutralize ammonia, avoid precipitate formation, inhibit oxidation reaction, extend oil life, reduce bubble formation, and improve lubrication efficiency.
