Manufacturer's description

Eni Alaria 3 is a high performance heat transfer fluid. Made from deeply refined mineral base oils, it is characterised by excellent oxidation stability and resistance to thermal cracking at high operating temperatures. Eni Alaria 3 can be used in any forced-circulation plant, closed or open. In modern closed systems, under controlled conditions, in the absence of air and atmospheric pressure or in systems pressurised with inert gas, the maximum operating temperatures are 300 °C for the bulk oil and 320 °C for the oil film. In open systems the presence of air affects the product's thermal stability, and the maximum bulk oil temperature is 180 °C. If the oil is held above the recommended temperatures it will degrade, with vapour bubbles appearing in the circuit and a drop in both the flash point and the service life of the product.

Applications

• 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.

Performance & benefits

• 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

Standards & approvals

• ISO 6743-12 QB

  Quenching oil QB — ISO 6743-12

  Class QB of the ISO heat-treatment (quenching) oil classification (family Q): a quenching oil whose cooling rate is accelerated by additives.
