Principles to follow during the operation of electric heater external components:
1. First, fully understand the temperature requirements of the heater, and select the appropriate duct-type electric heater equipment. Generally, the higher the power, the faster the heating, and the shorter the heating time, and vice versa.
2. Electric heater equipment is strictly prohibited from dry burning, especially immersion electric heating elements, which are made of stainless steel 304.
3. Choose the appropriate power of the electric heating tube, and pay attention to the power load issue while ensuring effective operating temperature.
4. Fully understand the operating environment of the electric heating tube, whether it is medium conduction or infrared radiation.
5. Fully understand the wiring method of the electric heater, usually star connection and three-star connection. A single electric heating tube can be connected to 220V or 380V, and multiple electric heating tubes can be directly connected to 380V.
Functional features of electric heater:
1. Small size, high power: The heater mainly uses clustered tubular electric heating elements.
2. Fast thermal response, high temperature control accuracy, and high overall thermal efficiency.
3. High heating temperature: The maximum operating temperature of the heater design can reach 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 places, 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 design surface power load and multiple protections, greatly enhancing the safety and 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 connected to a computer network.
8. Significant energy-saving effect, almost 99.99% of the electric energy is transferred to the heating medium.
