These are the oils used in the casting melting furnace of MotulTech, of which we are the regional dealer in the field of special hydraulic oils, and are called fireproof hydraulic oils in the industry. In addition, they are special hydraulic groups that work at high temperatures or very low temperatures in specially fixed aluminum extrusion presses, machines where proportional valves are used extensively, and work machines. These are oils with a high viscosity index, prepared by refining from special group base oils, and the product will be determined by our technical team.
