Description

Perfecto^TM HTS 16 is a high-temperature synthetic heat transfer fluid. It has a higher thermal stability than conventional mineral oil heat-transfer fluids, and thus can be used at bulk temperatures up to approximately 20°C / 68°F higher. It has low vapour pressure, high specific heat and high thermal conductivity.

Application

Perfecto HTS 16 is recommended specifically for use in non-pressurized liquid-phase systems that operate at bulk fluid temperatures in the range 320°C - 350°C / 608°F - 662°F, and at maximum film temperature of 374°C / 705°F. (In systems where the bulk temperatures are below 320°C / 608°F, the mineral-based Perfecto HT 5 may be used). Where the expansion-tank temperature exceeds 50°C / 122°F a nitrogen blanket should be employed, to minimize oxidation of the fluid. Before being commissioned, the system should be pressure-tested for leaks and thoroughly flushed through with Perfecto HTS 16. Under no circumstances should water be used. When the system has become clean, the flushing charge should be drained off and the system filled with Perfecto HTS 16. Careful venting should be carried out while the fluid's temperature is being raised, to remove all air and moisture from the system.
