Velol ® 19 machine oil is an antifreeze oil derived from refined petroleum distillates.
It contains additives to improve lubricity, viscosity and temperature properties, additives to improve foaming resistance, as well as corrosion and oxidation inhibitors.
There are two types of machine oils, Velol ® 9Q and Velol ® 19. The numbers describing the type of oil indicate the lower limit of its kinematic viscosity at 20 o C. ISO 3448
