Circulating Electric Heater I. Overview: Circulating electric heater is an internationally popular high-quality, long-life electric heating equipment. It is used for heating, maintaining temperature, and warming flowing liquid or gaseous media. When the heating medium passes through the heating chamber under pressure, it uniformly带走 the huge heat generated by the electric heating elements using fluid thermodynamics principles, raising the temperature of the heated medium to meet user process requirements. Working Principle: The circulating electric heater converts electrical energy into thermal energy to heat the required material. During operation, low-temperature fluid medium enters the input port through a pipe under pressure, flows along a specific heat exchange channel inside the electric heating container designed based on fluid thermodynamics principles,带走 the high-temperature thermal energy generated by the electric heating elements, raising the temperature of the heated medium. The outlet obtains the high-temperature medium required by the process. The internal control system of the electric heater automatically adjusts the output power based on the temperature sensor signal at the outlet, ensuring uniform outlet temperature. When the heating element overheats, the independent overheat protection device immediately cuts off the heating power, preventing coking, deterioration, carbonization due to overheating, and effectively extending the service life of the electric heater. II. Application Scope: Typical applications include: 1. Chemical material heating, powder drying under pressure, chemical processes, and spray drying. 2. Hydrocarbon heating, including crude oil, heavy oil, fuel oil, thermal oil, lubricating oil, paraffin, etc. 3. Process water, superheated steam, molten salt, nitrogen (air), water gas, etc. 4. Due to advanced explosion-proof structure, it can be widely used in chemical, military, petroleum, natural gas, offshore platforms, ships, mining areas, etc. III.
