Thermal oils should have a high heat transfer as their main property.
Water is the best medium for heat transfer, but has its limitations at colder and higher temperatures. That is why extremely thin types of oil (chemicals) are used for this. These are still liquid far below the freezing point and have a much higher boiling point than water.
The lower or higher the desired temperature is, the higher the bar of properties must be set for quality, read: chemical stability,
The synthetic thermal oils consist of different types of raw materials and compositions, which give each product its specific and unique properties.
At Rodun International BV, many products are available for a temperature range from -115ºC to + 400ºC.
In addition to excellent heat transfer, chemical stability must also be taken into account
wear for high thermal fluid durability.
The relative ratio of low-boiling and high-boiling formations and the solubility of the high-boiling fractions can vary widely and are critical factors in evaluating fluid properties, predicting top-up costs and the overall risk of product degradation.
