The air electric heater we usually said is a normal air electric heater, but it will have different characteristics of different models according to different models, so we will look at the characteristics of ordinary air electric heater today and wind Different characteristics of the cross air electric heater. Air electric heater air electric heater air electric heater air electric heater is mainly used to heat the required air flow from the initial temperature to the required air temperature, up to 850 ° C. It has been widely used to airborne aerospace, weapons industry, chemical industry and colleges indoor heater and universities, many research and production laboratory. It is especially suitable for automatic controlled temperature and large flow high temperature combined systems and accessories tests. The range of air electric heater uses wide range: can heat any gas, heat air, dry water, no conductive, no combustion, no explosion, no chemical corrosion, no pollution, safe and reliable, heated space heating fast ( Controlled) Characteristics of a normal air electric heater: 1. Air electric heater generally have two types: resistive wire electric heater and ceramic electric heater. 2. The electric resistance wire electric heater has two types of bare wire and tubular shape. 3. In actual engineering, there is a resistance wire electric heater and a ceramic electric heater. 4. The air electrical heater must be chained with a blower. Bottom sequence: air blower —- electric heater; shutdown sequence: air electric heater —— (1 minute) blower. The air electric heater must not be opened when the blower is not opened. 5. Air electric heater and metal air tubes to install air electric heater should be excellent ground. 6. The air tube in the range of 0.8 meters before and after the air electric heater, and its insulation material should be used in an insulating non-combustion material. Forming air electric heater technology features: 1, can heat the air to a very high temperature, can reach 450 ° C, the housing temperature is only about 50 ° C. 2, high efficiency: up to 0.9 or more. 3, temperature rise and cooling rate block, up to 10 ° C / s, fast and stable. The air-shaped air electric heater does not appear the controlled air temperature and lag, which makes the temperature control drift, and is very suitable for automatic control. 4, the mechanical properties are good: because the heating body of the wind-type air electric heater is a special alloy material, it is better than the mechanical properties and strength of the high pressure air flow, which is better than any heat generating body. The system and accessory test of the air temperature during long periods of continuously have more superiority. 5. When not violates the use procedures, the long-term durable and service life is decades. 6, air is clean, small size. 7, can design multiple types of air electric heater according to the needs of users.
