Air duct heater
Working principle
Air duct heater is mainly used for air heating in the duct, specifications are divided into low temperature, medium temperature, high temperature three forms, the common place in the structure is the use of steel plate to support the electric pipe to reduce the vibration of the electric pipe, the junction box is equipped with overtemperature control device. In addition to the control of the overtemperature protection, but also installed between the fan and the heater, to ensure that the electric heater must be started after the fan, before and after the heater added a differential pressure device, in case of fan failure, the channel heater heating gas pressure generally should not exceed 0.3Kg/cm2, if you need to exceed the above pressure, please choose the circulating electric heater; Low temperature heater gas heating higher temperature does not exceed 160℃; Medium temperature type does not exceed 260℃; High temperature type does not exceed 500℃.

Working condition application overview
Air duct frame type electric heater, mainly acting on the flow of air in the air duct heating, can be directly installed in the required heating environment of the pipe, the use of steel plate to support the electric heat pipe, air duct heater for industrial pipes, air conditioning pipes and various industrial air, by heating the air to increase the temperature of the output air. Usually inserted into the lateral opening of the air duct.
The inner cavity of the air duct electric heater is provided with a plurality of baffles (deflectors) to guide the gas flow direction and extend the retention time of the gas in the air duct, so that the gas is fully heated, the gas is heated evenly, and the heat exchange efficiency is improved. The heating element of the air duct electric heater is a stainless steel heating tube, which is filled with electric heating wire in the seamless steel pipe, and the void part is filled with magnesium oxide powder with good thermal conductivity and insulation. When the current passes through the high-temperature resistance wire, the heat generated is diffused to the surface of the heating tube through the crystalline magnesium oxide powder, and then transferred to the heated gas to achieve the purpose of heating.
Application
Air duct electric heater is mainly used to heat the required air flow from the initial temperature to the required air temperature, up to 500 ° C. It has been widely used in aerospace, weapons industry, chemical industry and many scientific research and production laboratories in colleges and universities. It is especially suitable for automatic temperature control and high flow and high temperature combined system and accessory test. The electric air heater can be used in a wide range: it can heat any gas, and the generated hot air is dry and water-free, non-conductive, non-burning, non-explosive, non-chemical corrosion, pollution-free, safe and reliable, and the heated space is heated fast (controllable).
