Air Pipeline Electric Heater
Working principle
The air pipeline electric heater is composed of two parts: body and control system.Electric heating element generates heat: The electric heating element in the heater is the core part of generating heat. When an electric current passes through these elements, they generate a lot of heat.
Forced convection heating: When nitrogen or other medium passes through the heater, the pump is used to force convection, so that the medium flows and passes through the heating element. In this way, the medium, as a heat carrier, can effectively absorb heat and transfer it to the system that needs to be heated.
Temperature control: The heater is equipped with a control system including temperature sensor and PID controller. These components work together to automatically adjust the output power of the heater according to the outlet temperature, ensuring that the medium temperature is stable at the set value.
Overheating protection: In order to prevent overheating damage to the heating element, the heater is also equipped with overheating protection devices. As soon as overheating is detected, the device immediately cuts off the power supply, protecting the heating element and the system.

Product advantage
1, the medium can be heated to a very high temperature, up to 850 ° C, the shell temperature is only about 50 ° C;
2, high efficiency: up to 0.9 or more;
3, the heating and cooling rate is fast, up to 10℃/S, the adjustment process is fast and stable. There will be no temperature lead and lag phenomenon of the controlled medium, which will cause the control temperature drift, suitable for automatic control;
4, good mechanical properties: because its heating body is special alloy material, so under the impact of high pressure air flow, it is better than any heating body mechanical properties and strength, which requires a long time continuous air heating system and accessories test is more advantageous;
5. When it does not violate the use process, the life can be as long as several decades, which is durable;
6, clean air, small size;
7, the pipeline heater can be designed according to the needs of users, multiple types of air electric heaters.
Working condition application overview
The working principle of the horizontal air duct electric heater is mainly based on the process of converting electrical energy into heat energy. Specifically, they are heated by internal electric heating elements, which are usually metal heating elements, such as nickel-chromium alloy, capable of maintaining high resistivity and emitting uniform heat at high temperatures. When the air flows through the electric heater, these heating elements exchange heat with the air through convective heat transfer, thus heating the air.
In the horizontal air duct electric heater, the air flows through the pipe under pressure, and the high temperature heat generated by the electric heating element is transferred through a path designed by the principle of fluid thermodynamics to heat the air to the required temperature. In addition, the internal control system of the electric heater automatically adjusts the output power according to the temperature sensor signal at the output outlet to maintain the uniformity of the temperature of the medium. When the heating element exceeds the temperature, the independent overheat protection device will automatically cut off the heating power supply to avoid the overtemperature of the heating material, thus effectively extending the service life of the electric heater
