What are the application areas of electric tubular heater? What are the characteristics?

- Aug 07, 2020-

The electric tubular heater uses stainless steel as the sheath, magnesium oxide rod as the inner core, magnesium oxide powder filler, and nickel-chromium wire as the heating wire. It can be roughly divided into single-end electric tubular heater and double-end electric tubular heater.


"Stainless steel" refers to its material. Electric tubular heater, scientific name metal tubular heating element, the most commonly used. Classification of stainless steel electric tubular heaters: single-end electric tubular heaters, double-end electric tubular heaters, stainless steel electric tubular heaters, heat sink electric tubular heaters, water heating electric tubular heaters, dry heating tubular heaters, mold electric tubular heaters, high-temperature color-changing hoses, hot runner electric heating coils, cigarette equipment Electric tubular heaters, tubular heater for pharmaceutical machinery, heating tubes for electroplating equipment, Teflon heaters, titanium heating rods, far infrared tubular heater, ceramic heating tubes, titanium lead-free tin furnace heating tubes, heating coils, plastic machinery heating coils, etc.


The application range of electric tubular heaters is stainless steel finned electric tubular heaters, which can be installed in blowing ducts or other static and flowing air heating occasions; in metal stamping, machinery manufacturing, automobiles, textiles, food, home appliances and other industries, especially in air conditioning Electric heating tubes in the air curtain industry and stamping industry are widely used as hot air components. The common shapes and structures are: I type (straight tube), U type, W type (M type), O type (ring), etc.


Features of electrictubular heater:

1. Energy saving is the biggest feature of electric heating tubes

Carbon fiber is a pure black body material. During the electrothermal conversion process, visible light is very small, and the electrothermal conversion efficiency is more than 95%.

1.1 Compared with nickel-chromium, tungsten-molybdenum and other materials as heaters, it can save energy by 30%;

1.2 Boiling water can save energy by 15.5%.

1.3 Under the same power, the radiation temperature is 30℃ higher than that of nickel-chromium metal electric heating tube, and 15℃ higher than that of tungsten-molybdenum wire quartz electric heating tube.

1.4 The far infrared rays emitted by it are directly absorbed by the human body, clothing, water, etc., and the heat loss is small during the heat transfer process, and the energy saving is strong;

1.5 is more absorbent to carbohydrates, has a good carbon atom resonance effect, and greatly improves product efficiency.

2. The characteristics of the electric heating tube also include no instantaneous current impact

The ignition does not require a ballast, and there is no pulse current impact when starting, which simplifies the lighting power supply and protection circuit, and prolongs the service life of the power supply and related electrical appliances.

3. The heat radiation direction of the electric heating tube is high, which can improve the design directional heat radiation.

4. Environmental protection is the biggest feature of carbon fiber electric heating tubes

4.1 No light pollution, no eye irritation and skin burns

4.2 No ultraviolet radiation and harmful gas

4.3 No high-frequency radiation (only far-infrared radiation), no microwaves, electromagnetic waves, and the ability to absorb harmful light waves.

5. The light radiation of the electric heating tube is concentrated in the infrared band between 1.5-15μm.

 What are the advantages of the electric heating tube compared with the infrared light of the metal heating element

6. The electric heating tube has strong acid resistance and corrosion resistance
