SPC HEAT TRANSFER OIL 4A 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 4A 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
PC HEAT TRANSFER OIL 4A is recommended for all 'open' or 'closed' type units with:

• maximum boiler outlet temperature of 305
