- The high quality of eni Alaria ID guarantees their resistance to high-temperature degradation, thus preventing deposit and sludge formation.
- High-grade refining prevents deposit and sludge formation during operation, while the superior quality level ensures thermal stability up to temperatures where cracking starts.
- The paraffinic base stocks is refined to guarantee good demulsibilty and air-separation performance, thus ensuring proper operation of the heat transfer unit, by preventing the formation of steam and air bubbles at the hottest points.
- The heat characteristics of eni Alaria ID remain practically unchanged while in service, due to the very good oxidation resistance of these oils and their high-temperature stability.

eni Alaria ID 2 and 3 can be used in closed type units with: ˗ Maximum boiler outlet temperature 285°C ˗ Maximum boiler wall temperature 315°C eni Alaria ID is also suitable for open type unit with maximum temperature 150°C (eni Alaria ID 2 and 3) and 160°C (eni Alaria ID 5). Higher working temperatures reduce oil life; the closer the working temperature to the cracking temperature and the longer that condition persists, the shorter the life. eni Alaria ID is also suitable for lubricating textile and glass-making machinery, for the preparation of silk-screen printing impasses in the ceramic industry, for the cutting of small ferrous and non-ferrous parts, for soaking plant fibres and as process oil in the production of ceramics and rubbers.
When starting-up a new unit or when restarting after maintenance: 1. Increasing gradually the bulk temperature 20°C per hour to release residual air 2. Maintain a while during the temperature at 120°C - 140°C and again at 170°C - 190°C to release steam and gas through expansion tank and any release valve (if available) 3. Increasing gradually the bulk temperature to get operational/working temperature
