Currently, heat transfer oil is widely used in industries such as paper crushing, wood, cement production, chemical production, etc., is a popular choice for many consumer businesses with its ability to protect and maintain the operation of the heat transfer system.

1. What is heat transfer oil?

Heat Transfer Oil (also known as Heating Oil, Heat Transfer Oil, Heat Transfer Oil, Insulating Oil, etc.) is a compound made from 85% high-grade base oil and 15% from a dedicated additive system for heat transfer systems. Oil with heat transfer ability, high thermal stability, high viscosity index, high flash point helps heat transfer system or heat exchanger operate at the required temperature as well as ensure absolute safety for system.

Widely used in heat transfer systems of industries such as processing, food, chemical plants, textile manufacturing, wood, paper, plastic, cement, asphalt cooking and dissipation equipment oil heat...

In which, heat transfer oil plays the role:

• Cooling, heating oil, insulation oil, heat carrier oil.
• In many industrial applications, heating is provided indirectly by circulating hot oil through a heat exchanger. This mechanism contributes to the reduction of hot spots and increased safety of the heating process.
• Heat transfer oils help to remove impurities in natural gas processing operations.
• By providing the right temperature, this oil helps to resist oxidation, preventing the formation of carbon and organic acids on metal surfaces.

2. Notes when using heat transfer oil

The heat transfer system, whether new or old, should be thoroughly cleaned and disinfected before it is put into operation. If necessary, use alkaline cleaning chemicals. When using detergents, they are usually pumped with hot water and continuously pumped in the system to remove deposits.

The system needs to be sealed to prevent hot oil from coming into contact with the air in the storage tank, otherwise the oil will oxidize very quickly. To do so, the equipment must have a residual expansion oil tank located in a suitable position so that the oil in this tank has a temperature lower than 55 degrees Celsius.

The amount of oil must always be maintained through the heater regardless of the operating mode of the heat exchanger. A pipeline parallel to the heat exchanger should be designed to conduct part of the oil when there is no requirement to pass all the oil through the heat exchanger. This helps to ensure that adequate oil flow is maintained through the heater.

In particular, it is recommended to regularly test the oil in use to check the viscosity, acid index, flash point and insoluble residue content in the oil. Sampling is recommended within a few days of system startup and then every 6 months thereafter. Usually the degree of change in the characteristics of the oil sample will dictate whether the heat transfer fluid should be continued or replaced.
