SPC HEAT TRANSFER OIL 3A is formulated from carefully selected paraffinic base stocks used for heat transfer systems. It has excellent oxidation and thermal stability and is able to withstand decomposition.

Benefits
SPC HEAT TRANSFER OIL 3A provides the following benefits:

• Resistance to high-temperature degradation, thus preventing deposit and sludge formation.
• Prevents deposit and sludge formation during operation, while the superior quality level ensures thermal stability up to temperatures where cracking starts.
• Good demulsibility 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 transfer characteristics of the oil remain practically unchanged while in service, due to the very good oxidation resistance of the oil and their high temperature stability.

Application
SPC HEAT TRANSFER OIL 3A is recommended for all 'open' or 'closed' type units with:

• maximum boiler outlet temperature of 305 Deg C.
• maximum boiler wall temperature of 320 Deg C.

CAUTION
When starting-up a new unit or when restarting after maintenance, and also in the case of irregular operation at normal temperature caused by residual moisture in the oil, the temperature of the unit should be reduced to around 100 deg C. All steam should be blown off before returning to the normal working temperature.
