Electric heater has heating core and protective tube
1. This electric heater consists of a heating core and a protective tube. The heating core uses tubular electric heating elements as the heat source. The protective tube is made of thin stainless steel, which has a large heat dissipation area and fast heat transfer. The terminal device part is divided into ordinary type (using iron-made stretched cup-shaped cover) and special type (using bolted explosion-proof device cover seal). The special type meets the requirements of explosion-proof mark dIICT4 and protection level IP65 series standards.
2. During design, the contact area between the protective tube and the heated oil should be considered to prevent local carbonization of the oil due to excessive heating temperature. This model of heater is only suitable for heat transfer oil or oil with good heating effect and for internal heating in media. 3. The electric heater is connected to the oil tank container body by flange. The protective tube isolates the heating core from the heated oil. When repairing the electric heater, there is no need to drain the oil in the tank; only the heating core needs to be pulled out and replaced with a new one, making maintenance convenient.

This electric heater consists of a heating core and a protective tube. The heating core uses tubular electric heating elements as the heat source. The protective tube is made of carbon steel tube or stainless steel tube, which has a large heat dissipation area and fast heat transfer. The terminal device part is divided into ordinary type using iron-made stretched cup-shaped cover, and special type using bolted explosion-proof device cover seal. It meets the requirements of explosion-proof mark dⅡBT4 and protection level IP54 series standards. The electric heater is connected to the oil tank body by flange. The protective tube isolates the heating core from the heated oil. When replacing the electric heater, there is no need to drain the oil in the tank; only the heating core needs to be pulled out and replaced with a new one, making maintenance convenient. The protective tube has a large contact area with the heated oil, so the oil will not carbonize due to local high temperature. Long service life, safe and reliable.
