Brief introduction:
1. This electric heater consists of a heating core and a protective sleeve. The heating core uses a tubular electric heating element as the heat source, and the protective sleeve is made of thin stainless steel. It has a large heat dissipation area and fast heat transfer. Electric heater HRY5 220V 8KW sheathed heater 380V 8KW The terminal device part is divided into ordinary type (using iron drawn cup-shaped cover) and special type (using bolted flameproof device cover 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 protective sleeve isolates the heating core from the heated oil. When maintaining the electric heater, it is not necessary to drain the oil in the tank. Only need to extract the heating core and replace it with a new one, which is convenient for maintenance.
3. When designing, the contact area between the protective sleeve and the hot oil should be considered to prevent local carbonization of the oil due to excessive heating temperature. This type of heater is only suitable for heating heat transfer oil or oil media with good heat receiving effect.

Process:
The heating tube is made by inserting electric heating wire into an outer tube (carbon steel tube, titanium tube, stainless steel tube, copper tube), filling the gap with magnesium oxide powder with good thermal conductivity and insulation, then shrinking the tube. After heat treatment process (some tubes do not need), it is processed into various shapes required by users. It has simple structure, high thermal efficiency, good mechanical strength, and good adaptability to harsh environments. Electric heater HRY5 220V 8KW sheathed heater 380V 8KW can be used for heating various liquids and acid-base salts, and is also suitable for melting metals with low melting points.
Scope of use of tubular heaters: suitable for heating air, oil, water, chemical media, hot pressing molds, melting salts, alkalis, and low melting point alloys, etc. It has the characteristics of high thermal efficiency, long service life, high mechanical strength, easy installation, safety and reliability.
