Heat Transfer Oil
Hational Heat Transfer Oil ISO VG SAE VG 32 20L 205L
Description
National heat transfer oil is formulated with high viscosity index base oils and a selective advanced additive package to ensure a high level of thermal conductivity & specific heat thermal stability. Paraffinic heat transfer fluids for use in closed unpressurized heat transfer systems operating at bulk oil temperatures up to 320°C, and are widely used in the petroleum chemical industry, synthetic fiber, synthetic resin, medicine, printing and dyeing, and other industries.
Features and Benefits
- Velocity of 1.5 m/s (5 ft/s) for operating temperatures below 200°C (400°F).
- Velocity of 2.0 m/s (10 ft/s) for operating temperatures between 200 and 260°C (400 and 500°F).
- Velocity of 3.0 m/s (10 ft/s) for operating temperatures between 260 and 300°C (400 and 575°F).
- Velocity of 3.5 m/s (12 ft/s) for operating temperatures above 300°C (575°F)
The application limits of heat transfer oils depend first on circulating speed, and second on temperature in closed circuit systems. In general, the minimum velocities vs. temperatures are as follows:
