Insulation measures within the range of thermal oil heaters

1. To ensure the proper service life and heat transfer performance of the thermal oil, never operate a thermal oil heater at excessive temperatures.
2. Thermal oil heater manufacturers should carefully inspect the system during operation to prevent the entry of water, acids, alkalis, and low-boiling-point substances. The system should be equipped with filters to prevent the ingress of various impurities and ensure oil purity.
3. For oil or gas-fired boilers using Sida thermal oil as the heat transfer medium, the system should be equipped with an expansion tank, oil storage tank, safety components, measuring instruments, and control devices.
4. When commissioning a thermal oil heater, start the circulating oil pump at the beginning of operation. Allow it to run for half an hour before igniting and raising the temperature. During initial operation, increase the temperature slowly, approximately 20°C per hour. Once the temperature reaches 180-200°C, maintain the temperature for a period of time before commissioning. 5. After six months of use, a thermal oil heater should undergo an oil analysis. If poor heat transfer or other abnormalities are observed after extended use, the oil should be analyzed. The oil should be replenished or replaced based on the analysis results. The following criteria should be met: Alkaline Carbon No. 1.0%, Acid Value No. 0.5 mgK(OH)/g, Flash Point Change No. 20%, Viscosity Change No. 10%. If any of these criteria are exceeded, the oil should be replaced.
