It is widely used in the high-temperature refining process of oil processing, the setting and drying equipment in textile printing and dyeing, and the heating links of some special chemical synthesis reactions, providing a solid heat guarantee for these high-temperature, high-pressure, and technically demanding production processes and helping enterprises achieve high-quality production goals.

Mineral Heat Transfer Oil

  • Thermo – M1 (Maximum Operating Temperature 280°C): Based on high-quality mineral oil and refined and formulated through a special process, it has good heat conduction performance and a moderate Price, with obvious cost-effective advantages. It can operate stably in general industrial heating systems and meet the heat transfer needs of most conventional industrial productions. Its kinematic viscosity at 40°C is 30.1 mm²/S, 5.8 mm²/S at 100°C, with a viscosity index of 95, a pour point of -15°C, and a flash point of 180°C. It is suitable for hot presses in wood processing, heating tanks in small food processing enterprises, and heat exchangers in heating and heating supply systems. While ensuring a certain heat transfer efficiency, it saves equipment operation costs for enterprises and is an ideal choice for users with limited budgets and relatively low heating temperature requirements.
  • Thermo – M2 (Maximum Operating Temperature 300°C): It has relatively high thermal stability among mineral heat transfer oils and can adapt to relatively high-temperature working environments. It has good anti-emulsification performance and can effectively prevent emulsification when water is mixed in, which may affect the heat transfer effect. The kinematic viscosity at 40°C is 35.6 mm²/S, 6.5 mm²/S at 100°C, with a viscosity index of 100, a pour point of -12°C, and a flash point of 195°C. It is often used in some medium-temperature reaction processes in the chemical industry, injection molding machine heating in plastic processing, and dye vat heating in the textile industry. In these application scenarios, it can not only meet the process temperature requirements but also ensure the normal operation of the equipment and the stability of product quality with its relatively good stability and anti-emulsification properties.

Guide to Selecting Heat Transfer Oil

When choosing heat transfer oil, multiple factors need to be considered comprehensively. First, clarify the maximum heating temperature requirements in the industrial production process. If the temperature is relatively high and strict stability is required, such as in the in-depth processing of the petrochemical industry, synthetic heat transfer oil should be preferred; if the temperature is relatively low and the budget is limited, such as in the simple heating process of small food processing, mineral heat transfer oil may be more suitable. Secondly, consider the material and operating conditions of the equipment. Some special material equipment may have requirements for the corrosiveness of the heat transfer oil. At this time, products with stable chemical properties and low corrosiveness need to be selected. In addition, pay attention to the viscosity characteristics of the heat transfer oil. Appropriate viscosity can ensure good fluidity and heat transfer efficiency in the system. For example, in a low-temperature startup environment, low-viscosity heat transfer oil is more conducive to rapid circulation and heat transfer.

Key Points for the Use and Maintenance of Heat Transfer Oil

Usage Points

  • During installation, ensure that the pipeline connection of the heat transfer oil system is tight and leak-free. Install it strictly in accordance with the design requirements and perform sufficient exhaust operations to prevent air resistance from affecting the heat transfer effect.
  • Before starting the heat transfer oil system, conduct a comprehensive inspection of the equipment, including whether the instruments are normal and whether the valve opening and closing states are correct. The startup process should be slow heating to avoid sudden temperature rises that may cause local overheating of the heat transfer oil or a sudden increase in system pressure.
  • During operation, closely monitor the changes in parameters such as temperature, pressure, and flow to ensure that they are within the normal range. If abnormal fluctuations are found, the cause should be promptly investigated. It may be equipment failure, heat transfer oil degradation, or system blockage, etc., which need to be dealt with in a timely manner.

Maintenance Points

  • Regularly filter the heat transfer oil to remove impurities and sediments to prevent them from depositing on the surface of the pipeline and heat exchanger and affecting the heat transfer efficiency. It is recommended to perform a filtering operation every 6 months according to the usage situation.
  • Regularly test the quality indicators of the heat transfer oil, such as acid value, viscosity, and flash point. When these indicators exceed the specified range, it indicates that the heat transfer oil may have deteriorated and needs to be replenished with new oil or replaced in a timely manner. Generally, a comprehensive oil quality test is carried out every 1 years.
  • If water is found to be mixed in the heat transfer oil system, it should be dehydrated in a timely manner. Vacuum dehydration or adding a dehydrating agent can be used to avoid emulsification of the heat transfer oil caused by water or vaporization at high temperatures, which may lead to system failures.

Actual Application Case

A large pharmaceutical enterprise adopted our Thermo – S2 synthetic heat transfer oil in its reactor heating system. Before using it, the enterprise faced problems such as unstable temperature control in the reactor, decreased heat transfer efficiency due to coking of the heat transfer oil, and high costs caused by frequent replacement of the heat transfer oil. After using Thermo – S2, through its excellent thermal stability and anti-coking performance, the heating efficiency of the reactor was significantly improved, and the reaction temperature could be accurately controlled within ±2°C, effectively improving the production quality and output of drugs. At the same time, no coking phenomenon occurred during continuous operation for more than 5 years, greatly extending the service life of the heat transfer oil and reducing equipment maintenance and heat transfer oil replacement costs, bringing significant economic and production benefits to the enterprise.
