HRY6 Sheath Type Electric Heater
Darui Electric recommends for you
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, which has a large heat dissipation area and fast heat transfer. The terminal connection part is divided into ordinary type (using iron-made drawn cup-shaped housing) and special type (using bolted explosion-proof housing seal). 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 from 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 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 other oils with good heat reception, and for internal heating of media.
HRY6/HRY7 Sheath Type Electric Heater Materials
Common outer tube materials include In800, In840, 304, 316L, 310S, aluminum, copper, low carbon steel, etc.
Magnesium oxide powder is selected according to different usage requirements, including high-temperature powder, medium-temperature powder, etc.
The resistance wire serves as the heating element, with two common materials: Ni-Cr wire and Fe-Cr-Al.
Lead terminal materials generally include two types: stainless steel and free-cutting iron.
Sealing materials include: epoxy, silicone, glass, etc.
HRY6/HRY7 Sheath Type Electric Heater Features:
1. Small size, high power: The heater mainly uses bundled tubular electric heating elements.
2. Fast thermal response, high temperature control accuracy, high overall thermal efficiency.
3. High heating temperature: The heater is designed with a maximum working temperature of up to 850°C.
4. Uniform medium outlet temperature, high temperature control accuracy.
5. Wide application range, strong adaptability: The heater can be used in explosion-proof or ordinary environments, with explosion-proof grade up to dⅡB and C, and pressure resistance up to 20MPa.
6. Long life, high reliability: The heater is made of special electric heating materials, with low surface power load design and multiple protections, greatly increasing the safety and service life of the electric heater.
7. Fully automatic control: According to requirements, through the heater circuit design, automatic control of parameters such as outlet temperature, flow, pressure can be easily achieved, and it can be networked with computers.
8. Significant energy-saving effect, almost 100% of the electrical energy is transferred to the heating medium.
