Electric heater features

Electric heater features

1. Small size and large power: The heater mainly uses bundled tubular heating elements.

2, fast thermal response, high precision temperature control, high overall thermal efficiency.

3, high heating temperature: heater design high working temperature up to 850 °C .

4, the media outlet temperature is uniform, high temperature control accuracy.

5, a wide range of applications, adaptability: The electric heater can be applied to explosion-proof or ordinary occasions, explosion-proof grade up to dIIB class and C class, pressure up to 20MPa .

6, long life and high reliability: The heater is made of special heating materials, the design of the surface power load is low, and the use of multiple protection, so that the safety and life of the electric heater is greatly increased.

7, can be fully automated control: According to the requirements of the heater circuit design, can easily achieve the outlet temperature, flow, pressure and other parameters of automatic control, and computer network.

8. The energy-saving effect is remarkable. The heat generated by electric energy is transferred to the heating medium by almost 100% .

The electrical energy is converted into heat energy to heat the object. It is a form of electrical energy utilization. Compared with the general fuel heating, electric heating, gives a relatively high temperature (e.g., arc heating, up to a temperature of 3000 deg.] C), easy to implement automatic temperature control and remote control, the vehicle-mounted electric heater may need to be heated object held A certain temperature distribution. The electric heating can directly generate heat inside the object to be heated, so that the heat efficiency is high, and the heating speed is high. According to the heating process requirements, the overall uniform heating or local heating (including surface heating) can be achieved, and vacuum heating and controlled atmosphere heating can be easily achieved.

In the process of electric heating, less exhaust gas, residue and smoke are generated, and the heated object can be kept clean without polluting the environment. Thus, the electric heater Electric heater, is widely used in the production, research and testing and other fields. In particular, electric heating is used in the manufacture of single crystals and transistors, mechanical parts and surface hardening, smelting of ferroalloys, and manufacture of artificial graphite. Depending on the mode of the power converter, electric resistance heating is typically divided into heating, induction heating, arc heating, electron beam heating, infrared heating and dielectric heating.
