Main technical indicators:

1. Reduce preheating time by more than 2/3;

2. Intelligent multi temperature zone control;

3. The heating temperature can reach 600 ℃;

4. Working principle of reducing environmental temperature: Efficient heating converts electrical energy into electromagnetic effects, causing the heated object to sense electromagnetic energy.

And its heating method adopts high oscillation current, changing the traditional diffusion heating from inside to outside and using infiltration heating from outside to inside, thus avoiding the problems of low heating efficiency and low thermal energy utilization of traditional methods. The relative energy saving rate is over 60%, and the thermal effective energy is increased from about 32% to about 95%. The energy-saving space is self-evident.

Product performance and environmental protection: Through outward inward directional infiltration technology, the external heat is relatively small, reducing the ambient temperature and avoiding manual high-temperature operations. Reduce environmental temperature, extend equipment lifespan, improve production efficiency and worker productivity, and significantly reduce equipment and enterprise cooling costs.

Improving the working environment: The high-efficiency and energy-saving heating method adopts internal heating, where heat is concentrated inside the heating element and there is almost no external heat dissipation. The equipment surface can be touched by hand, and the ambient temperature has been reduced from above 40 ℃ when heated by the resistance coil to room temperature, greatly improving the working environment of the production site, reducing the cost of ventilation and cooling in the factory area, and effectively improving workers’ production enthusiasm.

Simple installation technology: Efficient and energy-saving equipment does not require changing or damaging the original equipment structure, but can directly remove the original resistance coil and apply it on the surface of the heating element without changing the original working principle and heating method, with stable, safe and reliable performance.

The post What are the application advantages of electromagnetic heating energy-saving technology? appeared first on Ran Zhi China.

Firstly, to answer this question, it is necessary to explain the theory of electromagnetic heating. Usually, in resistance heating, the conduction method is used, which involves first applying a thermoelectric wire to a conduit (load) and exposing certain wires to external air radiation. Raise the surrounding temperature. Therefore, a large amount of heat is lost. The selection of induction cookers has a completely different heating principle. This is an eddy current method with a very high load, and its position thermal efficiency is as high as 95%. The resistance type uses conductive methods, and its heat generation is very low, only 60% of the power. Therefore, electromagnetic heaters can save more than 30% of electricity. I believe many people know this.

When the resistance wire is heated, some heat will be transferred to the cylinder, and this part of the heat will be lost to the air. In daily use, the loss of heat can even exceed 50%, which makes the thermal energy utilization rate of resistance heating low and leads to long heating time.

Electromagnetic heaters generate a magnetic field through high-temperature coils. The coil itself does not generate heat. It heats the barrel through eddy current induction and wraps it with insulation cotton to prevent heat loss, resulting in high heat utilization efficiency. In the case of a water granulator, the refrigeration unit can heat up to a temperature exceeding 400 degrees Celsius within 10 minutes. As for the high heating temperature, it depends on the material. Usually, after iron is heated to a red color, its temperature no longer increases. We usually operate at around 500-600 degrees. If you want to heat the temperature even higher. Then you must use another machine or change the material of the load (such as graphite steel pot), usually a temperature of 500-600 degrees Celsius is sufficient for plastic machines.
