1. The working principle is different: in heat conduction oil heater, heat is transferred by circulating heat transfer oil, while in heat conduction oil furnace, after the heat transfer oil is heated to a certain temperature, the heat is transferred to the heated object through a heat exchanger. Electric heating heat conduction oil furnace is to heat the heat-conducting oil to a certain temperature through an electric heater, and then transfer the heat to the heated object through a heat exchanger.
2. Different heating methods: heat conduction oil heater and heat conduction oil furnace usually use gas, oil or electric heater for heating, while heat conduction oil furnace uses electric heater for electric heating.
3. Different scope of application: heat conduction oil heater is suitable for occasions requiring heating, such as chemical industry, medicine, food and other industries. Heat conduction oil furnace is suitable for occasions requiring high-temperature heating, such as paint, coatings, plastics and other industries. Electric heating heat conduction oil furnace is suitable for occasions that need precise temperature control, such as printing, electronics, aviation and other industries.
4. Different maintenance: heat conduction oil heater and heat conduction oil furnace need to change the heat transfer oil regularly and clean the oil circuit and flue, while electric heating heat conduction oil furnace needs to check the working state of the electric heater and the connection of the circuit regularly.
In a word, heat conduction oil heater, heat conduction oil furnace and heat conduction oil furnace all use heat transfer oil as heat transfer medium, but there are still some differences between them, so it is necessary to choose the appropriate equipment according to the specific use occasions and needs.
