HEAT TRANSFER OIL
Tridon Therm oils are paraffinic heat transfer fluids for use in closed unpressurized heat transfer systems operating at bulk oil temperatures up to 315ºC (600F). They provide excellent resistance to thermal cracking and chemical oxidation and are non-toxic, have a very low odor level and have no detrimental effect on selected seals. They provide high specific heat and thermal conductivity at all temperatures and therefore give rapid heating and efficient operation of the heat transfer system.
Tridon Therm oils can be used up to bulk oil temperatures of 315ºC (600F). Tridon Therm 22, 32, 46 and 68 has high specific heat and thermal conductivity at all temperatures and, therefore, will give rapid heating and flexibility in a system. The characteristics of these products make them ideal where high heat transfer rates combined with high flow rates are desired. Tridon Therm is especially suited for systems where heating and cooling cycles are required since it functions effectively at both high and low temperatures and repeated thermal cycles.
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:
- Velocity of 1.5 m/s (5 ft/s) for operating temperatures below 200ºC (400F).
- Velocity of 2.0 m/s (7 ft/s) for operating temperatures between 200 and 260ºC (400 and 500F).
- Velocity of 3.0 m/s (10 ft/s) for operating temperatures between 260 and 300ºC (500 and 575F).
- Velocity of 3.5 m/s (12 ft/s) for operating temperatures above 300ºC (575F).
