ESh oil

ESH oil for hydraulic systems of highly loaded mechanisms (GOST 10363-78) is a medium-viscosity distillate, which undergoes deep selective-treatment and deparaffination followed by the addition of a polymeric thickener and a pour point depressant. Designed for hydraulic control systems of highly loaded mechanisms (walking dredges and other similar machines). It is efficient in the temperature range from -40°С to +(80-100)°С.
