Thermal fluid is the core heat transfer medium of a thermal fluid heater, and its service condition directly determines the heating efficiency, equipment stability and service life of the whole system. Regular replacement of thermal fluid is an essential part of daily equipment maintenance for industrial production lines.
Under standard normal operating conditions with stable temperature, clean fuel and standardized operation, the thermal fluid of industrial thermal fluid heaters needs to be replaced every 12 to 18 months. For production lines with long-term 24-hour continuous operation, high-temperature load and frequent start-stop, the replacement cycle should be shortened to 8 to 12 months. During operation, if the thermal fluid turns dark black, generates peculiar smell, produces sediments or causes slow temperature rise of the heater, it indicates medium aging and deterioration, and immediate replacement is required regardless of the service time.
Timely replacement of thermal fluid can effectively prevent pipeline coking, pipe blockage and equipment overheating failure, and reduce operation and maintenance costs. As a professional thermal fluid heater manufacturer, we recommend users to establish a complete maintenance record system to monitor the medium status in real time and ensure long-term stable and efficient operation of the heating equipment.
