The most important production processes:
We cut pipes made of stainless steel in such a way so that they get the right length for the designed heating elements. The pipes serve as the outer sheath of the heater. We always choose the right grade of stainless steel depending on the conditions in which a given heater is to work.
In order to make a suitable resistance element, we wind a spiral of Kanthal or Nikrothal resistance wire onto a matching mandrel. Thanks to this, the produced element will quickly release heat to the outside of the heater.
To ensure reliable isolation of the spiral from the casing tube, we cover the resistance element in the stainless steel tube with magnesium oxide. We use high quality magnesium oxide, which affects the excellent electrical insulation of the heater with very good thermal conductivity.
The rolling process serves to reduce the outer diameter of the heater. This way magnesium oxide inside the heater thickens, which significantly increases its heating parameters, allowing to achieve the best results.
Heating in furnaces at approx. 1000 ° C
Annealing heating elements in high-temperature furnaces, which can reach a temperature of up to 950°C, softens the casing pipe. This allows to bend the heaters so that they match the previously designed shapes.
Annealed elements are subjected to bending on numeric benders. Thanks to this, we achieve the desired shape of the entire element.
Heaters are soldered into heads or flanges. We use brazes that perfectly combine stainless steel and non-ferrous metals. This affects the perfect tightness of the connection, which allows the heaters to work in tanks with liquids.
We always achieve the most precise connection of components with the heating element. All thanks to reliable Tig welding.
Bonding is used to connect various types of current outputs in heaters. It provides a secure connection of the heater end to the current output element. It's a fast, repeatable and effective process.
