Complete Specifications Sheath Type Electric Heater

Brief Introduction:

1. This electric heater consists of a heating core and a sheath tube. The heating core uses tubular electric heating elements as the heat source, and the sheath 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 housing) and special type (using bolted explosion-proof device housing sealed). The special type meets the requirements of explosion-proof mark dIICT4 and protection level IP65 series standards.

2. The electric heater is connected to the oil tank container body by flange. The sheath 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 extracted and replaced with a new one, making maintenance convenient.

3. During design, the contact area between the sheath and the heated oil should be considered. The oil will not be locally carbonized due to excessive heating temperature. This model of heater is only suitable for use with heat transfer oil or oil with good heat transfer effect and for internal heating of media.

Complete Specifications Sheath Type Electric Heater Note: When selecting, the actual conditions of the heating medium and the installation dimensions of the equipment should be considered. The surface heating power should be as far as possible ≤0.7 W per square centimeter. During wiring, appropriate high-temperature wires should be used to connect the power distribution control box to the electric heater.
