Product Data Sheet

NOCO HEAT TRANSFER OIL 21

NOCO HEAT TRANSFER OIL 21 is manufactured from selected paraffinic type crude oils by modern refining processes. It has a high viscosity index (VI), so viscosity change is minimal over a broad temperature range. Under recommended service conditions, it resists both oxidation and thermal attack and offers excellent resistance to cracking and sludge formation. It is recommended for closed circulating hot oil systems with maximum sustained operating temperatures of 232 C (450 F) and maximum short duration temperature spikes to 288 C (550 F).

NOCO HEAT TRANSFER OIL 21 is not recommended for open systems.

BENEFITS

High thermal efficiency for rapid and efficient heat transfer
High thermal stability to resist excessive breakdown
High viscosity index with low viscosity to permit easy circulation
Low vapor pressure at elevated temperatures to prevent pressure buildup
No offensive odours caused by cracking or other degradation
Long service life for proven trouble-free operation.
