Product Features:
1. This model of electric heater is manufactured based on imitation of 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 tube. The wiring device is protected with a bolted cover shell, which is waterproof, moisture-proof, and oil-proof.
2. The protective tube and the oil tank body are connected with straight thread, providing strong sealing. The protective tube isolates the core from the heated oil. When replacing the electric heater, there is no need to drain the oil from the tank; simply extract the heater core, 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 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. All the heat generated is 100% transferred to the medium, with extremely high thermal efficiency.
2. The electrical junction box is made with a flameproof structure, allowing safe operation 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 overheated, allowing timely control to prevent damage.
5. The safety factor of the immersion electric heater manufactured by our company is much higher than national regulations, with long service life and good insulation performance.
