Thermal oil electric heater is an industrial heating device that uses electrical energy to heat thermal oil and transfers the heat to the heating equipment through a circulation system. Its core characteristics are precise temperature control, high thermal efficiency, and strong safety, widely used in industries such as chemical, petroleum, plastic, textile, and food.

Key selection points

Heating power: calculated based on the heat load of the heating equipment (such as heating time and heat dissipation loss).

Type of thermal oil: Choose synthetic oil suitable for high temperatures (such as biphenyl ether mixture).

System pressure: Design the pressure bearing capacity of the pipeline (usually ≤ 0.5MPa).

Explosion proof requirements: Explosion proof heaters should be used in flammable and explosive environments.

maintenance

Regularly replace the thermal oil: usually 2-3 years or determined based on the results of oil testing.

Cleaning pipelines: Remove carbon deposits and impurities to ensure heat transfer efficiency.

Check electrical components: avoid dry burning of heating tubes or insulation aging.

Comparison with traditional heating methods

Comparison item: Thermal oil electric heater, steam boiler, gas heating

The temperature range can reach 350 ℃, usually ≤ 180 ℃ (normal pressure), limited by combustion efficiency

Direct conversion of energy consumption into electrical energy, efficiency>95%, large heat loss (pipeline condensation) dependent on gas prices

Environmentally friendly zero emissions require treatment of wastewater with CO ₂ emissions
