Duralife Heat Transfer oil is blended from high viscosity index base oils with oxidation inhibitors to enhance high temperature performance and stability.
APPLICATIONS:
Duralife Heat Transfer oil is recommended for use in closed heat transfer systems with a bulk temperature of 320oC maximum and a skin temperature of 360 oC maximum and for use in open systems with the maximum temperature should not exceed 200 oC at the point where the oil is exposed to the air.
BENEFITS:

S Excellent thermal stability and resistance to oxidation and thermal cracking at high temperatures, hence avoiding the formation of oxidation sludges which may affect efficient heat transfer.
S 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 hottest points.
S With a low pour point , it has good pumpability in cold weather start-up , thereby providing good circulation and diminishing the likelihood of hot spots.
S High specific heat and thermal conductivity coupled with a suitable viscosity enable it to conduct and distribute large amount of heat efficiently.

The above characteristics are average values based on recent production. Minor variations, which do not affect product performance, are to be expected in normal manufacture.
WARNING:
Continuous contact with used oil has caused skin cancer in animal tests. Avoid prolonged contact. Thoroughly wash exposed areas with soap and water. Keep out of reach of children.
Don't pollute. Conserve resources. Return used oil and bottle to collection centers
