1.the surface power is large, is 2 ~ 4 times of air heating surface load.
2. highly dense, compact structure. Because the whole is short and dense, so the stability is good, installation without bracket.
3. the combined type mostly uses argon arc welding to connect the electric heating tube with the flange, but also can use the form of fastening device, that is, each electric heating tube is welded with fasteners, and then the flange cover with the nut locking, pipe and fastener using argon arc welding, no leakage. Scientific technology is adopted in the sealing part of the fastener, which is very convenient for single replacement and greatly saves the maintenance cost later.
4. choose imported and domestic materials, scientific production process, strict quality management, to ensure the excellent electrical performance of the electric heating tube.
