compressed air heater

Short Description:

compressed air heater as a special electric heating equipment, in the design and production process, must comply with the relevant explosion-proof codes and standards. The explosion-proof electric heater adopts explosion-proof structural design and explosion-proof housing, which can effectively prevent the impact of sparks and high temperature generated by electric heating elements on the surrounding flammable gas and dust, thus avoiding potential safety hazards. Explosion-proof electric heater also has multiple protection functions, such as over-current protection, over-voltage protection, lack of phase protection, etc., which can effectively protect the safety of the equipment itself and the surrounding equipment.

Working principle

The compressed air 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

When air is compressed, the distance between the air molecules becomes smaller, resulting in an increase in the average kinetic energy of the molecules, which generates heat. This heat is called the heat of compression. Compressed air will produce a certain temperature during the production process, but this temperature may not reach the rated temperature required by users.

In order to reach the desired temperature and keep it constant, the compressed air needs to be reheated using a heating device. The heater converts electrical energy into heat energy through an electric heating element, heating the fluid medium (such as compressed air) and raising its temperature.

The heater is equipped with an electric heating element, and when the compressed air flows through the heater, the temperature sensor at the outlet will test the temperature of the compressed air. If the temperature does not meet the requirements, the heating unit automatically starts to heat the compressed air through the electric heating element.

The heater uses a digital display of real-time temperature, and the temperature is adjusted by a potential regulator. The temperature measuring element and control module complete the measurement calculation and control loop to realize the control of the heating component. The measurement signal is sent to the control module for amplification and comparison and displayed on the display screen. At the same time, the analog quantity of 4~20mA can be output outwardly to realize remote external monitoring.

The compressed air pipeline heater achieves precise temperature control and heating of compressed air by using the auxiliary heating of electric heating elements to meet the needs of different application scenarios
