A guide baffle is installed inside the shell to ensure even heating during air circulation

The electric heater body is composed of multiple tubular electric heating elements, a shell, a protective cover, a base, and other components. The heater is a tubular electric heating element made of high-temperature resistance alloy wire, with stainless steel tubes as protective sleeves and crystalline magnesium oxide fillers. It is formed by compression process and has the characteristics of good mechanical strength, high thermal efficiency, wear resistance, and corrosion resistance. A guide baffle is installed inside the shell to ensure even heating during air circulation.

The working principle of the control cabinet is to use an intelligent digital temperature controller, high-power thyristor, and thermal resistance to form a measurement, adjustment, and control circuit. Using a thermal resistor to convert the outlet temperature of the heater into a milliampere signal, it is sent to an intelligent digital temperature controller for amplification, comparison, and display of the corresponding temperature value. When the displayed value is higher than the set value, the thyristor does not conduct. When the displayed value is lower than the set value, the intelligent digital temperature controller triggers thyristor conduction. When the displayed value is close to the set value (i.e. entering the vicinity of the set value), the intelligent digital temperature controller changes according to P, I, and D rules, making the control cabinet have good control accuracy and adjustment performance. The intelligent digital temperature controller automatically changes the number of triggering pulses of the thyristor based on the milliampere signal sent by the thermal resistance, that is, controls the conduction angle of the thyristor within a unit time, adjusts the voltage, controls the heating power of the heating element, ensures energy conservation and constant temperature, avoids current shocks, and extends the service life. When the device suddenly shuts down and restarts, the control cabinet can automatically adjust smoothly.

1. It can heat the air to a very high temperature, up to 850 ℃, and the shell temperature is only about 50 ℃.

2. High efficiency: up to 0.9 or above.

3. The air is clean and the volume is small.

4. Multiple types of air electric heaters can be designed according to user needs.

5. Durable and long-lasting, with a lifespan of several decades, when not in violation of usage regulations.

6. The heating and cooling rate block can reach 10 ℃/S, with fast and stable adjustment. There will be no phenomenon of controlled air temperature leading or lagging, which will cause temperature control drift and uncertainty, making it very suitable for automatic control.

7. Good mechanical performance: Because its heating element is made of specially made alloy material, it has better mechanical performance and strength than any heating element under the impact of high-pressure air flow. This is more advantageous for systems and accessories that require long-term continuous heating of the air.
