1- RENOLIN THERM

Description
RENOLIN THERM oils are paraffinic heat transfer fluids for use in closed un-pressurized heat transfer systems operating at bulk oil temperatures up to 315°C (ISO 22 to 150). For ISO 5 & 10 the maximum bulk operating temperature is 200 oC.

They provide excellent resistance to thermal cracking and chemical oxidation and are nontoxic, have a very low odour 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.

Application
RENOLIN THERM grades have 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. RENOLIN THERM 22 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 (400oF).

· Velocity of 2.0 m/s (7 ft/s) for operating temperatures between 200 and 260oC (400 and 500oF).

· Velocity of 3.0 m/s (10 ft/s) for operating temperatures between 260 and 300oC (500 and 575 oF).

· Velocity of 3.5 m/s (12 ft/s) for operating temperatures above 300oC (575 oF).
