Resistors used as the main equipment in channel-type electric heaters are produced in two different types: tubular and coiled. The resistance tube is made of AISI 304 quality stainless steel material. The resistance is produced by centering the Ni/Cr 80/20 wire in the middle of the stainless tube, filling it with MgO powder under vibration, and compressing the MgO powder. Once filled, the resistors are annealed in special tempering ovens for easy bending and annealing processes. M14 brass nuts are used at the ends of the resistance, ensuring easy assembly of the resistance to the casing.
Resistors can be produced in Ø6.5 mm, Ø8.5 mm, and Ø11 mm diameters depending on technical specifications such as channel dimensions or usage areas. Coiled resistors are obtained by winding a coil made of AISI 304 stainless material on the resistor produced as a tube using special winding machines.
