How to Accurately Control the Temperature of the Air Channel Heater
Date of issue:2020-06-19  Reading times:[835]

The air heater is mainly used for air heating in the air duct. The standard is divided into three ways: low temperature, medium temperature and high temperature. The common structure is to select steel plate to support the electric heat pipe to reduce the oscillation of the electric heat pipe. The junction box is equipped with overtemperature control equipment. ?

In addition to over-temperature protection, intermodal transport equipment is also installed between the fan and heater to ensure that the electric heater must be started after the fan starts, and a differential pressure equipment is added before and after the heater to prevent the fan from breaking down. The gas pressure heated by the channel heater should not exceed 0.3Kg/cm2 generally. If the above pressure is to be exceeded, the low temperature type heater should be selected. The maximum heating temperature of heater gas does not exceed 160 C; the medium temperature type does not exceed 260 C; and the high temperature type does not exceed 500 C. The air channel electric heater is used for industrial air duct, air conditioning air duct and air of various industries to heat the air and increase the temperature of the output air. It is usually inserted in the lateral opening of the air duct. According to the working temperature of the duct, it can be divided into low temperature, medium temperature and high temperature, and according to the wind speed in the duct, it can be divided into low wind speed, medium wind speed and high wind speed. ?

The advantages of duct heater are also obvious, small size and high power.
