Product Description

This product is formulated using high-quality synthetic low-pour-base oil, combined with a variety of premium additives—including extreme-pressure, anti-wear, antioxidant, rust-inhibiting, and anti-corrosion agents—through advanced manufacturing processes. It delivers outstanding cold-temperature performance, making it ideal for outdoor use in extremely cold regions.

Product Performance

Outstanding viscosity-temperature and low-temperature performance ensure that the hydraulic system maintains excellent cold-start capability and pumpability even in cold conditions.

Outstanding wear resistance, corrosion and rust prevention, and oxidation stability—these properties help slow down equipment wear and extend its service life.

Outstanding emulsion-breaking, anti-foaming, air-release, and filtration properties ensure precise system power transmission;

Outstanding shear resistance ensures that the oil maintains excellent viscosity stability even under demanding operating conditions.

Technical Specifications

GB 11118.1-2011

Scope of application

Suitable for outdoor machinery operating in extremely cold regions (above -40°C), as well as medium- and high-pressure hydraulic systems exposed to significant temperature fluctuations or demanding operating conditions—such as those found in construction equipment, building machinery, mining machines, oilfield equipment, marine vessels, and vehicles.

Instructions for Use and Precautions

According to equipment lubrication guidelines, select oil products with the appropriate viscosity. During use and storage, prevent contamination by foreign objects, and strictly avoid mixing in mechanical impurities or water. Ensure the oil tank remains clean—when changing the oil, thoroughly flush both the tank and oil lines—and never mix it with oils of different types.
