RAIDO Hetroil is transformer oil is a good refined mineral oil with a very big specific resistance. Moreover this is a thin oil, so that the eventually developed heat can quickly be removed by a good circulation. By addition of special additives this oil obtained the following properties:
- a very good high specific resistance
- a very good removal of heat
- a low vapour tension and "tangent delta" value
- a high breakdown voltage
RAIDO Hetroil is heat-transfer oil is suitable for use as heat-transfer medium in closed circulating type heat-transfer systems, which work with indirect heating and high temperatures (above 100 °C.
Up till 300 °C the system will function without an inert type of gas. When the bulk oil temperature comes between 300 °C and 320 °C there has to be a slight overpressure of an inert type of gas.
