BGY8 Explosion-proof Electric Heater
1. This model of electric heater is manufactured by imitating German products. The electric heater consists of a heating core and a protective tube. The heating core uses tubular electric heating elements as the heat source, and the protective tube is made of thin stainless steel tubes. The wiring device protection adopts a bolted cover seal, which is waterproof, moisture-proof, and oil-proof.
2. The protective tube and the oil tank body are connected by straight pipe threads, with strong sealing performance. The protective tube isolates the core from the heated oil. When replacing the electric heater, there is no need to drain the oil in the tank; only the heater core needs to be pulled out, making maintenance convenient.
3. The surface power of this model of electric heater is designed according to the JBT2379-93 standard, and its surface power should be selected at ≤0.7W/cm2.

Product Introduction:
It is widely used in the 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, and the electrical junction box is outside the tank or container. Its characteristics are:
1. 100% of the generated heat is transferred to the medium, with extremely high thermal efficiency.
2. The electrical junction box is made into an explosion-proof structure, which can work safely in Zone I and Zone II explosive atmospheres.
3. The protection level reaches IP56, allowing long-term operation in the field and marine environments.
4. Typical temperature measurement points are set inside, and an electrical temperature control device can detect whether the heater is overheating, allowing timely control to prevent damage.
5. The immersion electric heater manufactured by our company has a safety factor far higher than national requirements, long service life, and good insulation performance.
