HTO Oil 68 Plus is used as heat transfer fluid in both closed and open heat transfer systems with forced circulation where a Mineral-type heat transfer fluid is required.
HTO Oil 68 Plus is suitable for open or closed heat transfer systems with forced circulation operating under the following conditions: Maximum bulk oil temperature: 288°C
Systems must have forced circulation of the heat transfer fluid.
Note for open systems:
Due to oxidation which is increased in open systems due to exposure to oxygen, the Life of any Mineral oil in an open system declines rapidly at temperatures beyond the region of 100°C. Therefore, a reduced service Life must be expected for these oils at higher temperatures in open systems.
