Eni Alaria 7 is a high performance product usable as a fluid for transfer of thermal energy to diathermic systems. Made by highly refined bases oils, at the reccommended operating temperatures they are characterized by an excellent oxidative stability and thermal cracking resistance.
Eni Alaria 7 can be used in any type of plant, either open or closed system and under forced circulation. In well-designed modern closed systems, in a controlled condition, in air absence and atmospheric pressure or in pressurized inert gas systems, the maximum operating temperatures are:
• Maximum bulk oil temperature: 300°C
• Maximum oil film temperature: 315°C
In open systems, the presence of air affects the thermal stability of the product, the Maximum bulk oil temperature is 180°C.
If the operational oil conditions are at higher than recommended temperatures, it will be subject to degradation phenomena that could result in vapor bubbles formation in the circuit and in a sensitive reduction of the flash point and reducing the oil shelf-life.
