L-HV Low-Temperature Hydraulic Oil
L-HV10 / 15 / 22 / 32 / 46 / 68
Excellent viscosity-temperature properties and low-temperature fluidity ensure smooth starting and stable operation of hydraulic systems in cold environments, while also providing wear resistance, oxidation resistance, rust protection, and demulsibility to enhance system reliability and service life.
Product Description
Product performance: Excellent viscosity-temperature characteristics and low-temperature usability ensure good cold startability and pumpability of hydraulic systems at low temperatures; superior wear resistance, oxidation stability, anti-wear and anti-rust properties reduce equipment wear and extend service life; outstanding demulsibility, anti-foaming, air release, and filterability ensure accurate power transmission; excellent shear stability maintains oil viscosity under severe operating conditions; good compatibility with various conventional sealing materials ensures a leak-free system. Applications: Especially suitable for medium and high pressure hydraulic systems in construction machinery, mining equipment, oilfield machinery, ships, and vehicles operating in cold regions with significant temperature fluctuations.
