MOBILTHERM® 605
Mobiltherm® heat transfer oils must not be mixed with other oils, as this may impair the excellent thermal and oxidation stability, which could lead to a change in other properties and complicate the analyses for determining the oil's service life.
Mobiltherm® 605: Closed systems (up to 315º C), Open systems (up to 180º C)
Mobiltherm® heat transfer oils must not be mixed with other oils, as this can impair the excellent thermal and oxidation stability, which may lead to a change in other properties and complicate analyses for determining the oil's service life.
If the oil is used above the recommended operating temperature, a gas bubble may form, unless the equipment is designed to operate at a higher temperature by increasing the pressure with an inert gas such as nitrogen.
At higher temperatures, the oil's service life is shortened because thermal degradation increases significantly as the temperature rises above the recommended limit. In a well-designed installation, the temperature of the oil film in the heating element must be kept approximately 15°C to 30°C above the bulk temperature of the oil. Higher temperatures shorten the oil's service life and can lead to sludge and coking, which can impair heat transfer.
As with other mineral oils, Mobiltherm® heat transfer oils must only be used in systems equipped with a circulation pump. Systems in which only convection moves the oil do not provide sufficient flow to prevent localized overheating and rapid oil aging. Furthermore, these oils are not recommended for use in open installations where the hot oil is in direct contact with the air.
