Oil synthetic B3V
turbine oils
Description
Oil B3V used in gas turbine engines, helicopter gearboxes and other equipment with oil temperature at the outlet from the engine to 200 ° C
Oil BeV – based on synthetic esters of pentaerythritol and fatty acids with additives complex
.
Applications
applied in gas turbine engines, helicopter gearboxes and other vehicles with an oil outlet temperature from the engine to 200 ° C. It has high lubricity. Disadvantage: precipitation pressure agent at low temperature operation due to oxidation, followed by dissolving the precipitate in the oil at 70-90 ° C
.
