The difference between air tubular electric heater and compressed air electric heater

The difference between the electric heater and the compressed air electric heater is that the electric air heater can use a duct type electric heater or a duct type electric heater, and the compressed air electric heater can only use a duct type electric heater. The connection between the air electric heater and the compressed air electric heater is that both electric heaters can be used.

Compressed air, the air compressed by external forces. The air has compressibility, and the air compressor works mechanically so that the volume of the air is reduced. The compressed air is compressed air. Compressed air is an important power source. Compared with other energy sources, it has the following obvious features: clear and transparent, convenient transportation, no special harmful performance, no fire risk, no fear of overload, can work in many adverse environments, air everywhere on the ground, take it Inexhaustible.

The electric air heater is mainly used to heat the required air flow from the initial temperature to the required air temperature up to 850°C. Has been widely used in aerospace, weapons industry, chemical industry and universities and many other research and production laboratories. Especially suitable for automatic temperature control and high flow high temperature combined system and accessories test. Electric air heaters have a wide range of applications: they can heat any gas, and the resulting hot air is dry, dry, non-conductive, non-flammable, non-explosive, non-chemically corrosive, non-polluting, safe and reliable, and the heated space is heated quickly ( Controllable).

Duct-type electric heaters are mainly used for air heating in ducts. The specifications are divided into three forms: low temperature, medium temperature, and high temperature. Common in structure is the use of steel plates to support electric heating pipes to reduce the vibration of electric heating pipes. Both are equipped with over-temperature control devices. In addition to the convenience of control, in addition to the over-temperature protection, it is also necessary to add an intermodal transport device between the fan and the heater to ensure that the electric heater must be started before the fan starts and a differential pressure device is added before and after the heater to prevent the fan from heating. Fault, the gas pressure of the channel heater heating should not exceed 0.3Kg/cm2, if exceed the above pressure specifications, please use the circulating electric heater, the maximum temperature of the low-temperature type heater gas heating does not exceed 160 °C; medium temperature type does not exceed 260 °C; high temperature type does not exceed 500 °C.
