Ducted electric heaters are mainly used for air heating in air ducts, which are classified into low temperature, medium temperature and high temperature. A common feature of this structure is that the steel plate is used to support the electric heating tube to reduce the vibration of the electric heating tube, and it is equipped with an over-temperature control device. In addition to control and overheat protection, an intermodal device is installed between the fan and the heater to ensure that the electric heater must be activated after the fan is started and that the differential pressure device is added before and before. The air pressure of the duct heater should not exceed 0.3Kg / cm2. If you need to exceed the above pressure, use a circulating electric heater. The maximum temperature of the low temperature heater gas heating does not exceed 160 ° C; the medium temperature type does not exceed 260 ° C; the high temperature type does not exceed 500 ° C. Air duct electric heaters are used in industrial air ducts, air conditioning ducts, and air in various industries to increase the temperature of the output air by heating the air, and are typically inserted into the lateral openings of the air duct. According to the working temperature of the air duct, it is divided into low temperature, medium temperature and high temperature; according to the wind speed in the air duct, it is divided into low wind speed, medium wind speed and high wind speed.

Air duct electric heater product features

1. The electric heating tube adopts the production method of the outer corrugated stainless steel strip, which increases the heat dissipation area and improves the heat exchange efficiency.

2, the heater design is reasonable, in line with electric power, wind resistance is small, heating is uniform, no high, low temperature dead angle.

3, double protection, good security. The thermostat and fuse are mounted on the heater and can be used to control the air temperature of the duct over temperature and without wind to ensure safety.
