Operation of electric heat guns, their design features and selection criteria
Heat electric guns are widely used in production for heating the premises, for heating or drying of various parts, to reduce humidity in the rooms. The main nodes of thermal guns are the heating element and fan, on high -performance devices, the heated flow is able to immediately spread by several tens of meters.
With the power of the heating element up to 3 kilowatts, a nichrome wire is usually used, which has a high specific resistance. With three -phase power and greater power, closed heaters are used, in which the spiral consists in the airtight shell made of metal. The installation of heating elements significantly increases the electrical safety of devices and their durability.
Electric guns are necessarily equipped with thermal and current protection. Additionally, a switch and power regulator can be installed. The efficiency of thermal heaters will directly depend on the difference in air temperatures and the heating element. The choice of the heating unit is made based on the required temperature, room volume, and thermal leaks. An approximate guideline can be the calculation: 1 kW on10 m² premises.
