Complete Specifications Sheath-type Electric Heater

Brief Introduction:

1. This electric heater consists of a heating core and a protective sheath. The heating core uses tubular electric heating elements as the heat source, and the protective sheath is made of thin stainless steel. It 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 maintaining the electric heater, there is no need to drain the oil in the tank; simply pull out the heating core and replace it 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 heating heat transfer oil or oil with good heat transfer effect and 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 much as possible ≤0.7W per square centimeter. When wiring, appropriate high-temperature wires should be used to connect the distribution control box to the electric heater.
