When heating the air, the elements should be evenly arranged, so that the elements have good heat dissipation conditions, so that the air flowing through can be fully heated.Safety measures should be considered when heating nitrate to prevent explosion accidents.
Wiring part should be placed outside the insulation layer, avoid contact with corrosive, explosive media, water;The wiring should be able to withstand the temperature and heating load of the wiring part for a long time, and the wiring screws should be avoided when fastening too hard.Components should be stored in a dry place, if long-term placed below 1 m Ω insulation resistance, can be in around 200 ℃ oven drying, or lower voltage electric heat, until the insulation resistance.Magnesium oxide powder at the outlet of the electric heating pipe should be avoided by pollutants and water infiltration in the place of use to prevent the occurrence of electrical leakage accidents.
