Provides reduced toxicity without reduced performance

LE’s Low Tox® Turbine Oil (6412-6414) provides long-lasting performance, equivalent to conventional turbine oils while providing lower toxicity than biodegradable turbine oils. Its advanced technology formulation – with highly refined mineral oil and specially selected additives – offers low toxicity, but it does not sacrifice lubrication performance or necessitate shortening of lubricant change intervals; there is no worry of premature oxidation or failure of the lubricant as there is with most vegetable oil-based products. Low Tox Turbine Oil meets or exceeds OEM requirements for many generators, turbines and governors; it is especially suited for use in hydroelectric facilities and flood control structures requiring lubricants.

Why Low Toxicity?

N/A One question confronting scientists in environmental risk assessment is whether it is better for a material to be quickly biodegraded and possess relatively high toxicity or be low in toxicity and biodegrade at a slightly slower rate. Lubrication Engineers believes that the latter option provides the best protection of the environment because it minimizes overall impact on the ecosystem.
