Eni Alaria 3 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 3 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: 320°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.
CUSTOMER ADVANTAGES
• High thermal exchange properties, in forced circulation condition, ensures optimum heat
transfer
• Very high resistance to thermal cracking contributes to the control of the formation of
sludge and deposits
• Improves operational efficiency thanks to high thermo-oxidative stability
• Excellent demulsibility ensures the rapid and effective water separation
