Terralus BVG Hydraulic Oils are a range of readily biodegradable hydraulic oils manufactured to meet the requirements of hydraulic systems in industrial, horticultural and earth moving equipment. This range is mineral oil free and has been specially developed to meet concern over the inevitable spills, leakages and total system losses that frequently occur from burst hoses on hard worked hydraulic equipment. This is particularly important if hydraulic equipment is working where soil or water contamination is a possibility. In addition to the problem of mineral oil pollution, there is now evidence that zinc anti-wear additives in conventional hydraulic oils may have long-term harmful ecological effects. Terralus BVG Hydraulic Oils are completely free of zinc and all other heavy metals.
