The circulating industrial hot air blower adopts the patented cooling device, and the continuous air inlet temperature can reach 230 ℃ / 350 ℃. The standard air volume regulation adopts the frequency converter to adjust the speed, which is more energy-saving, high controllability and less heat loss. There are also one key start and close functions. The circulating industrial hot air blower is equipped with temperature resistant blower, which can recycle hot air and save about 50% - 80% electric energy consumption. It is especially suitable for heating, heating, drying and so on.

The circulating hot air blower is composed of three parts: fan part, heating part and control part. After passing through the volute of the medium pressure fan, the air becomes a fast flowing air flow. After the resistance wire is electrified, the resistance wire rapidly heats up and exchanges heat energy with the air flow, the air outlet blows out quickly, and works directly on the workpiece and space. The fan and heating are controlled by the control part as a whole. The temperature rise precision is high, the temperature rise time is short, the speed is fast, and the energy consumption is low.

After the hot air blower is powered on, the blower will blow the air into the heater, so that the air passes through the inside and outside of the spiral electric heating wire evenly. The heat generated by the electric heating wire after being electrified exchanges with the cold air passing through, so that the air temperature at the air outlet is increased. The thermocouple at the air outlet timely feeds back the detected air temperature to the temperature controller. The instrument monitors the actual working temperature according to the set temperature, and transmits the relevant information back to the solid state relay to control whether the heater works. At the same time, the fan can use the air volume regulator to adjust the air volume of the blowing air, so as to realize the control of the working temperature and air volume. In addition, the circulating industrial hot air fan also has over temperature protection circuit for the air inlet and motor of the fan and the emergency brake switch for the main circuit to further improve the protection of the equipment.
