The air duct electric heater is mainly used to heat the air in the air duct. This specification is divided into three forms of low temperature, medium temperature and high temperature. It is common in the structure to support the electric heating pipe with a steel plate to reduce the vibration of the electric heating pipe. The junction box is equipped with an over-temperature control device. In addition, in terms of control, in addition to over-temperature protection, a joint transmission device is installed between the fan and the heater to ensure that the electric fan heater must be started after the fan is started, and a pressure difference device is added before and after the heater to prevent fan failure.
The air pressure of the air pipe electric heater should not exceed 0.3kg≤cm2 .. If you need to exceed the above pressure, please choose a cycle electric heater; low temperature heater gas heating temperature does not exceed 160 ° C; medium temperature type does not exceed 260 ° C ; High temperature type does not exceed 500 ° C. The air pipe electric heater is an industrial air pipe, air conditioning air pipe and various industries. The air is heated to increase the temperature of the output air. Generally, it is inserted into the lateral opening of the air pipe. According to the working temperature of the air pipe, it can be divided into low temperature, medium Mild and high temperature; according to the wind speed in the duct, it can be divided into low wind speed, stroke wind speed and high wind speed ..

The electric tube heater is mainly used to heat the air from the initial temperature to the desired temperature, up to 850 ° C and higher. It has been widely used in aerospace, weapon industry, chemical industry, universities and many research and production laboratories. Especially suitable for high flow and automatic temperature control systems and accessories for thermotherapy testing. Wide range air electric heater is used: for any gas can be heated by drying moisture-free, non-conductive, non-combustible, non-explosive, non-chemical corrosion, safe, reliable, pollution-free hot air, fast The heating space is heated. The tube electric heater can heat the air to a very high temperature, up to 450 ° C, and the shell temperature is only about 50 ° C.
The heating and cooling speed block of the air tube electric heater can reach 10 ℃ / s, and the adjustment is fast and stable. It does not cause or lag behind the controlled air temperature, making the temperature control drift infinitely, which is suitable for automatic control. Because its heating element adopts special alloy material, it has better mechanical properties and strength under the impact of high pressure airflow than any heating element, which is more advantageous for systems and accessories that require long-term continuous air heating. Does not violate the use regulations, durable and has a service life of decades. The clean air and small volume are beneficial to the people. The air pipe electric heater adopts stainless steel heating pipe as the heating body, and carbon steel or stainless steel as the bracket, and adopts a combined connection method.
