Due to its characteristics such as uniform heat transfer and low operating pressure, heat transfer oil is being used more and more widely in various industries. However, some enterprises are prone to accidents due to the improper use of heat transfer oil, which can lead to its deterioration and other issues, affecting production and the economic efficiency of the enterprise. Therefore, proper use of the heat transfer oil system can effectively extend its lifespan and ensure stable production. I. Selecting the appropriate heat transfer oil is a prerequisite for ensuring its service life. When selecting heat transfer oil, the first thing to consider is choosing an appropriate one based on the process temperature. The service life of heat transfer oil is inversely proportional to its operating temperature. Therefore, when selecting heat transfer oil, it is necessary to consider not only meeting the temperature requirements of the production process but also ensuring the longest possible service life for the heat transfer oil. The maximum operating temperature of the heat transfer oil should be 20°C higher than the required temperature range to ensure safety and prevent the oil from suffering from overheating and degradation, which could affect its service life. Schulz Chemical provides customers with a range of Schulz SCHULTZ® synthetic heat transfer oil products that operate in a wide temperature range of -75°C to 400°C, meeting the diverse operational needs of clients in various industries around the world. II. Strengthening operation management is key to extending the service life. Choosing high-quality and suitable heat transfer oil is necessary, and it is also important to prevent overheating, oxidation, and contamination during use, as well as to enhance the following aspects of operation management. 1. Regularly sample and analyze the heat transfer oil to address any issues promptly. New oil must pass inspection before being introduced into the system; existing heat transfer oil should be sampled for inspection at least once a year. For those whose analysis results meet the **standard criteria for disposal, use should be stopped immediately and new oil should be replaced. The following items that meet the safety warning criteria should be addressed promptly: 1) Those with abnormal appearance should be checked immediately for leaks, and the inspection interval should be shortened. 2) In cases where there are abnormalities in the flash point, moisture content, or the distillation temperature of the 5% low-boiling compounds, check whether there are any abnormalities in the temperature of the heating furnace, and carry out dehydration and degassing operations promptly. And sampling for inspection can be carried out at any time as needed in the following situations: 1) A leakage accident occurs in the system ； 2) When the used heat transfer oil discharged from the system is reintroduced into the system ； 3) When other abnormal phenomena occur in the system. 2. Adhere to strict operating procedures and establish a scientific safety management system for the heat transfer oil system. During the operation of the heat transfer oil system, it is necessary to follow the operating procedures strictly to prevent overheating and thermal degradation ； Stabilize the flow rate to prevent localized overheating. Start and stop the furnace in accordance with the regulations. When stopping the furnace, do not stop the pump immediately; wait until the oil temperature drops below 70°C before stopping the pump. The system should be equipped with dual power supply or reliable emergency power failure protection mechanisms to prevent localized overheating and cracking of the heat transfer oil due to sudden power outages. Heat transfer oil acts like “blood,” supplying nutrients to the production equipment and influencing and controlling the quality of the products. We must pay attention to the heat transfer oil system in order to extend its service life, ensure the safe, reliable, and stable operation of the equipment, maintain normal production in the enterprise, and thus guarantee its economic viability. While providing customers with high-quality heat transfer oil products, Schulz Chemical also offers comprehensive and innovative 360° services throughout the entire product lifecycle. It provides consultation and product selection assistance during the pre-sales phase, training and commissioning support during the sales phase, and sample testing, operation and maintenance, as well as regeneration services after sales, all to ensure a longer service life for the heat transfer oil.
