Manufacturers of air electric heaters believe that the control of air electric heaters is very convenient

It's very cold in winter, and everyone likes to stay in places with air conditioning. Why? Of course it's because it's warm. A typical electric heater manufacturer heats it with water or some medium. For example, the commonly used electric kettle in our daily lives heats water through a kettle. The air electric heater manufacturer and it is an electric heating device used to heat airflow. How does the gas in the heated space work? The following is a brief introduction of the manufacturer of electric air heaters.

Electric air heater is an electric heating device that mainly heats the airflow. The heating element of the electric air heater is a stainless steel electric heating tube. The inner chamber of the heater is equipped with multiple baffles (guide plates) to guide the direction of the airflow, extend the residence time of the gas in the inner chamber, fully heat the gas, heat evenly, and improve heat exchange efficiency. The heating element of the air electric heater - stainless steel heating tube, is made by installing the electric heating wire into a seamless steel pipe, filling the gap with magnesium powder with good thermal conductivity and insulation, and then shrinking the tube.

When the current passes through the high-temperature resistance wire, the heat generated is diffused to the surface of the heating tube through crystalline magnesium powder, and then transferred to the heating air to achieve the purpose of heating. Both air electric heaters and compressed air heaters can use pipeline electric heaters. Pipeline electric heaters are mainly used to heat the required airflow from the initial temperature to the desired air temperature, while compressed air heaters can only use pipeline electric heaters. The air electric heater can be a tubular electric heater or an air duct electric heater, with a higher temperature of 850 ℃. Widely used in scientific research and production laboratories such as aerospace, weapons industry, chemical industry, and higher education institutions.

Electric heaters are particularly suitable for automatic temperature control, high flow and high temperature combined systems, and accessory testing. In addition to over temperature protection, a connecting device must be added between the fan and heater to ensure the start of the electric heater. After the fan is started, in order to prevent fan failure, a differential pressure device must be installed before and after the electric air heater. The gas pressure heated by the channel heater generally does not exceed 0.3kg/cm2. If the pressure exceeds the above specifications, please choose a circulating electric heater. The gas heating temperature of the low-temperature heater shall not exceed 160 ℃; Medium temperature type does not exceed 260 ℃; High temperature types shall not exceed 500 ℃.

Under the impact of high-pressure airflow, the heating element of the electric heater is made of special alloy. It has better mechanical properties and strength than any heating element, and is superior to continuous air heating systems and ancillary experiments in the long term. Under strict adherence to application procedures, the service life can exceed ten years. Fresh air is beneficial for environmental protection. Electric air heaters can heat air to very high temperatures, with the shell temperature only around 50 degrees. The efficiency is over 0.9, and the heating and cooling speed is fast, up to 10 ℃/s. Temperature control will not drift due to the controlled air temperature leading or lagging, making it very suitable for automatic control.
