Explosion-Proof Electric Heater for Oil Tanks Detailed Information:
Product Introduction:
It is widely used in petroleum, chemical and other industries for heating flowing or static liquids and gases in tanks and containers. The heating part of the immersion electric heater is completely immersed in the medium, while the electrical junction box is outside the tank or container. Its characteristics are:
1. 100% of the generated heat is transferred to the medium, resulting in extremely high thermal efficiency.
2. The electrical junction box is made with an explosion-proof structure, allowing safe operation in explosive atmospheres of Zone I and Zone II.
3. The protection level reaches IP56, enabling long-term operation in outdoor and marine environments.
4. Typical temperature measurement points are installed inside, allowing the electrical temperature control device to detect whether the heater is overheating, and to control it in time to prevent damage.
5. The immersion electric heater manufactured by our company has a safety factor far exceeding national requirements, with a long service life and good insulation performance.

Product Features:
1. This model of electric heater is manufactured by imitating German products. The electric heater consists of a heating core and a protective sleeve. The heating core uses tubular electric heating elements as the heat source, and the protective sleeve is made of thin stainless steel tubes. The wiring device is protected by a bolted cover shell, which is waterproof, moisture-proof, and oil-proof.
2. The protective sleeve is connected to the oil tank body with straight thread, providing strong sealing. The sleeve isolates the core from the heated oil. When replacing the electric heater, there is no need to drain the oil from the tank; only the heating core needs to be extracted, making maintenance convenient.
3. The surface power of this model of electric heater is designed according to JBT2379-93 standard, and its surface power should be selected at ≤0.7W/cm2.
