Circulating electric heater

Circulating electric heater uses a pump to force convection to circulate the fluid between the storage tank and the heater to heat various gases and liquids. If the power-pump-pipe-heater is fully functionally connected and has control components, it becomes a circulating electric heater system. Its integral skid-mounted frame is easy to move and install.

Features:

1. Solid structure, compact and sealed, high thermal efficiency.
2. The highest heating temperature can reach 950℃, which is not reachable by general heat exchangers.
3. It is designed for thermal load polar, with multiple protections such as anti-dry burning protection device, and the service life is factory.
4. It can be applied to ordinary and explosion-proof occasions. The explosion-proof grade can reach B and C grades, and the pressure resistance can reach 50Mpa. It can be vertical or horizontal according to user needs.
5. The system can realize automatic operation without daily maintenance. The heating control system includes both a simple and easy-to-use expert-level intelligent PID temperature control instrument control system and a powerful PLC control system. The control scheme can be flexibly selected according to different heating systems. Through a complete electrical control system, the heater outlet temperature constant temperature control and automatic control of parameters such as pressure and flow can be realized. The system can communicate with the user's DCS system through hard wire or communication to realize remote control.

application:

Compared with traditional heating methods, circulating heating has significant energy saving, scientific technology, convenient installation and use, high degree of automation, low investment, long life, and obvious economic benefits. It is widely used in petroleum, chemical, food, pharmaceutical, textile printing and dyeing, light industry, metallurgy, building materials, plastics, film and other industrial fields.

1. Heating of fluid media in oil fields, refineries, chemical plants and other industries.
2. Heating of polysilicon production materials such as hydrogen chloride, silicon tetrafluoride, and silicon powder.
3. All kinds of water heating, including water heating in civil cleaning rooms and industrial process water heating.
4. Heating of hydrocarbons, including heat transfer oil, fuel oil, asphalt, paraffin and so on.
5. Heating of washing machine and ice melting tank, including NaOH solution and various detergents.
6. Gas heating, including various inert gases and organic gas mixtures such as H2, N2, etc., to filter steam.
7. Air heating is suitable for drying some powders under normal pressure, chemical process and spray drying.
