The air duct electric heater is mainly used for air heating in the air duct. The specifications are divided into three forms: low temperature, medium temperature and high temperature. The common place in the structure is that the electric heat pipe is supported by steel plate to reduce the vibration of the electric heat pipe.
In addition to overtemperature protection, a combined transport device is also installed between the fan and heater to ensure that the electric heater should be started after the fan starts, and a differential pressure device is added before and after the heater to prevent the fan failure. The gas pressure heated by the channel heater should not exceed 0.3Kg/cm2 in general. If the pressure exceeds the above, please choose the circulating electric heater. Low temperature heater gas heating high temperature does not exceed 160℃; Medium temperature type does not exceed 260℃; High temperature type does not exceed 500℃. Air duct electric heater is used for industrial air duct, air conditioning duct and various industries by heating the air to improve the temperature of the output air, generally inserted in the transverse opening of the air duct. According to the working temperature of air duct, low temperature, moderate and high temperature; According to the wind speed in the duct, it can be divided into low wind speed, medium wind speed and high wind speed.
Air duct electric heater, using electric heating method to heat liquid, air drying. Full set of automatic control, power saving, no pipeline leakage, good working environment, rapid heating.
It is suitable for heating in liquid PH≥7, and can be made into daily tubular electric heating element dry burning tube, drying room, oven, static, flowing air, oil, water, press mold and other ways. Sanitary seamless stainless steel pipe, strong corrosion resistance, suitable for low concentration alkaline liquid heating; Duct electric heater adopts low surface power design of 5.6W/cm2 to ensure the service life of duct electric heater; The air duct electric heater has good stability and insulation performance, to eliminate the heater leakage, short circuit phenomenon which is often encountered in electroplating factory.
Generally speaking, the explosion-proof electric heating furnace is based on heat conduction oil as the heat carrier. The internal high temperature voltage system is forced to process by the circulating pump of heat conduction oil after electric energy, and the heat of the internal high temperature voltage is transported to one or more electric heating equipment. After the transition function in the high temperature voltage system of the electric heating equipment, the heat conduction oil begins a new heating operation power, that is, through the circulating pump again, back to the electric heating furnace to absorb heat twice and transmit it to the internal high temperature voltage system of the electric heating furnace. After this circulating operation, the electric heating furnace passes through the uninterrupted transfer of heat. The internal high temperature voltage system of electric heating furnace can obtain the power to continue high temperature. Then satisfy the heating medium in the process of high temperature heating demand.
