The heat transfer oil has the properties of resistance to thermal cracking and chemical oxidation, good heat transfer efficiency, fast heat dissipation and good thermal stability. As a heat transfer medium for industrial oils, heat transfer oil has the following characteristics: Under almost normal pressure conditions, high operating temperatures can be obtained. That is, the operating pressure and safety requirements of the high-temperature heating system can be greatly reduced, the reliability of the system and equipment can be improved, the process requirements of heating and cooling of different temperatures can be met in a wider temperature range, or the same type can be used in the same system. The heat transfer oil simultaneously achieves the process requirements of high temperature heating and low temperature cooling. That is, the complexity of the system and operation can be reduced; the water treatment system and equipment are omitted, the thermal efficiency of the system is improved, and the maintenance workload of equipment and pipelines is reduced. That is, the initial investment and operating costs of the heating system can be reduced.

      In the preparation of medical pharmaceuticals, raw material mixing, disposition, disinfection, distillation, evaporation, melting and other equipment and equipment heating requires heat transfer oil; in the chemical industry, heat transfer oil furnace is mainly used for distillation, evaporation, polymerization, condensation / De-milking, lipidation, drying, melting, dehydrogenation, forced insulation and heating of synthetic equipment such as pesticides, intermediates, antioxidants, surfactants, perfumes, etc.

Heat transfer oil should pay attention to the following problems in use:

1. The heat transfer oil must be stored indoors, strictly waterproof, acid and alkali mixed;

2. The heat transfer oils of different grades and varieties of different manufacturers cannot be mixed; if it is necessary to mix, it must be sent to the relevant unit for testing;

3, rinse or special cleaning agent cleaning; change the oil or overhaul to clear out the sediment;

4. The heating device with pump circulation should start the circulation pump first, then ignite after normal operation, open the exhaust valve, dehydrate and remove the light components, and close the small valve when the smoke is not used; during use, 100 °C Do not heat up too quickly, do not exceed 20 ° C per hour, stop using the pump when the heat transfer oil drops to 100 ° C;

5. The heat transfer oil should be inspected regularly (twice a year) to check the oil quality, extract the oil sample, carry out the test, and comprehensively analyze the indicators to determine whether to change the oil or refuel.
