Air duct heater is mainly used for air heating in the air duct, the specifications are divided into low temperature, medium temperature, high temperature three forms, the common feature in the structure is the use of steel plate to support the electric heating tube to reduce the vibration of the electric heating tube when the fan stops, and the junction box is equipped with an overtemperature control device. The low temperature type can be directly installed on the air duct, while the medium temperature type and high temperature type have a 100mm thick insulation material sandwiched from the outer wall of the channel to the heater junction box due to the difference in structure, which reduces the external heat dissipation of the entire channel on the one hand, and reduces the temperature in the wiring cavity on the other hand.
Air duct heater structure
1. The air duct heater adopts stainless steel heating tube as the heating element
2. Use carbon steel or stainless steel material as bracket
3. It is composed of a combined connection method
Air duct heater product features
1. The electric heating tube adopts externally wound corrugated stainless steel strip, which increases the heat dissipation area and greatly improves the heat exchange efficiency.
2. The heater design is reasonable, the wind resistance is small, the heating is uniform, and there is no high and low temperature dead angle.
3. Double protection, good security performance. A thermostat and fuse are installed on the heater, which can be used to control the air temperature of the air duct and work in the absence of wind to ensure that nothing goes wrong.
Air duct heater product applications: heating air, drying/vulcanization of various substances, heat treatment, reheating and dehumidification and other similar applications.
Technical characteristics of air duct heater products
1. It can heat the air to a very high temperature, up to 450 degrees Celsius, and the shell temperature is only about 50 degrees.
2. High efficiency, up to 0.9 or more.
3. The heating and cooling rate is fast, and the adjustment is fast and stable. There will be no leading and lagging phenomenon of the controlled air temperature and the temperature control will float, which is very suitable for automatic temperature control.
4. Good mechanical properties, because its heating element is a special alloy material, so under the impact of high-pressure air flow, it is better than the mechanical properties and strength of any heating element, which is more superior for systems and accessory experiments that require long-term continuous heating of air.
5. When it does not violate the use regulations, it is durable and has a service life of up to decades.
6. Clean air and small size.
Application areas of air duct heaters
Air duct heaters are 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 in aerospace, ordnance industry, chemical industry and colleges and universities and many scientific research and production laboratories. It is especially suitable for automatic temperature control and high flow high temperature combined system and accessory test.
Air electric heater has a wide range of use: it can heat any gas, and the hot air produced is dry and waterless, non-conductive, non-combustible, non-explosive, non-chemically corrosive, non-polluting, safe and reliable, and the heated space heats up quickly (controllable).
The company's main electric heater products: pipe heater, pipeline electric heater, heat transfer oil heater, electric heating stirring tank, jacket heating stirring tank, flange heater, air duct heater, heater, heavy oil heater, crude oil preheating heating, drying room, drying equipment, etc
