Comparison between electromagnetic heating furnace and resistance heating furnace

Electromagnetic heating furnace:

1, electromagnetic induction heating, real water-electricity separation, circuit water insulation.

2, low-voltage soft start, reduce the harm of current surge, avoid damage to equipment due to voltage fluctuation, and ensure safety.

3. The frequency conversion power output part can automatically adjust the control current according to the voltage fluctuation, so as to ensure the constant power, and will not be damaged due to insufficient power load caused by the increase of voltage and current.

Resistance heating furnace:

1, resistance heating, whether the resistance material is inside or outside, is conducted through the heat-conducting medium, which is not a real separation of water and electricity, and there are hidden dangers of dielectric corrosion or breakdown leakage.

2. The relay directly supplies power to the resistance bar, resulting in large impulse current, which is easy to cause overcurrent impulse and voltage fluctuation, and is also harmful to other electrical appliances.

structural design

Electromagnetic heating furnace: the whole structure is separated from water and circuit, with reasonable structure and high safety.

Resistance heating furnace: the water and electricity of the whole machine are not separated, which has great potential safety hazard.

conservation of energy

Electromagnetic heating furnace:

High-frequency electromagnetic induction heating directly acts on the water bladder through electromagnetic induction, so that the water bladder itself heats up, reducing the process of conduction through the medium, with less heat loss and high thermal efficiency. It can be heated immediately after being added without a heat storage container, and the instantaneous thermal efficiency can be as high as more than 98%, which is more than 30% more energy-saving than that of resistance type.

Resistance heating furnace:

1, resistance heating, heat is conducted to the water bag through the heat conducting medium, and the heat loss is large.

2, local fever, easy to produce scale, affecting heat conduction.

3. Some materials are seriously attenuated, resulting in low thermal efficiency.

life

Electromagnetic heating furnace: industrial electromagnetic, high temperature resistant, used for 15 years or more.

Resistance heating furnace: resistance wire is easy to age and has a short life, usually 3 to 5 years.

silent

Electromagnetic heating furnace: the frequency of heating power supply is 20000Hz, which exceeds the normal audio frequency of human body, which not only improves thermal efficiency, but also is silent and environmentally friendly.

Resistance heating furnace: the power frequency power supply has "buzzing" power frequency noise. When the surface water temperature is high, bubbles will make the sound of boiling water.

maintain

Electromagnetic heating furnace: electromagnetic induction heating. When working, the heating core component is a fixed magnetic field, and the water is magnetized after passing through, and the water structure is magnetized, so the system is maintenance-free.

Resistance heating furnace: generally, the resistance wire should be replaced once every 3 to 5 years, and the scale should be removed regularly.
