Molygrafit - Special Lubricants
OT-25 > 100% SYNTHETIC ESTER-BASED OIL. CONTAINS ADDITIVES THAT PROVIDE THERMAL STABILITY AND RESISTANCE TO OXIDATION.
MOLYGRAFIT OT-25 is a fully synthetic ester oil, suitable for the lubrication of gas turbines in various industrial sectors.
Its formulation includes additives that give the oil excellent thermal stability and oxidation resistance, providing a high degree of lubrication even at temperatures up to 250°C.
Because it is a synthetic lubricant, it adheres to metal surfaces, preventing dripping and sludge formation.
It has low consumption due to its low evaporation rate.
It has a high viscosity index, lubricating effectively at high temperatures.
Formulated with a metal binder and anti-corrosion agent, it protects equipment from corrosion.
MOLYGRAFIT OT-25 does not attack Viton seals or nitrile and silicone rubbers.
The lubrication interval and the volume of oil to be used will depend on the equipment manufacturer’s specifications.
Molygrafit OT-25 is a product that meets international and military standards for thermal turbines.
It is a non-toxic, biodegradable (OECD-301 B), and non-flammable product, offering complete safety to the operator.
