  • Technology


    The production is equipped with modern machines known and trusted manufacturers: Kanthal Machinery, Granlund, CSM Machinery, Rossler and others. It is organized into three independent production lines, enabling her flksibilnost and provided a diverse selection of heating elements.
    Due to its concept and equipment that differentiates us from other manufacturers, offers:
    - Large production capacity
    - Flexible production 
    - 100% control of the product during the process
    - Testing, examination, product development
    - New Product Development
    Our products are cost-effective, reliable, durable, good structure, corrosion resistant.
    Depending on the purpose of the heating element we care about the choice of surface pressure and power, that warm-up was optimal, but in order to avoid to load the heater.
    Selection of pipes is done on the basis of the environment and the purpose for which the element is made, and depending on the working temperature shell element temperature of the working environment, as well as vrest media that is heated.
    Tubular heaters are manufactured in lengths from 400 mm to 3000 mm, with that we can adapt the shape of customer request, taking into account the bending radius and its dependence on the type and diameter of the pipe heating element.

    For the production of heating elements, we choose the best materials.

    • All seamless copper tube Cu DHP which used in the production are subject to standard EN 12449 and EN 1057. Copper is an environmentally friendly material that can be recycled easily, and in accordance with that the acts and our production. Not only do we care about the quality, but also on resources.
    • When choosing a stainless steel take care about its purpose and quality, and we choose AISI 309 or AISI 316L depending on the working environment heater. Welded stainless steel pipes are made of the highest quality tapes known manufacturers such as Otelinox, Outokumpu, Terninox, subject to standard EN ISO 9445
    • Heating spiral made of a high-Kanthal D, Nikrothal-a, as well as the resistance wire of the famous German manufacturer BGH. FeCrAl alloys are used for temperatures up to 1300 ° C and are characterized by good resistance to oxidation. NiCr alloy has good ductility after use and excellent weldability.
    • It is very important to select the correct sealant, to prevent moisture absorption in the magnesium oxide. Therefore, we select the best - Wacker

  • Sketch cross section of tube heaters


    1. Heating spiral -resistant wire made of FeCrAl and NiCr alloys, resistant to high temperature.
    2. Electrically insulating mass made of visokočistog magnesium oxide (MgO), which serves as an electrical insulator and has a very good heat conductive.
    3. Terminal pins are designed for mounting electrical connections, while also serving to define negrejne zone electric heater. Linked with resistive wire using resistance welding.
    4. Insulating bead serves as insulation between the sheath heater (pipe) and the terminal pin. Beads are made of ceramics , C221 steatite
    5. Sealer - prevents the penetration of moisture into the interior of the heating element. For this purpose, the dedicated silicon with resistance to high temperature, dielectric strength of 21 kV / mm
    6. Pipe, tube of heating elements.Protective tube heaters may be made of copper or of stainless steel, ie. stainless steel. The maximum allowable temperature layer of copper pipe is 200 ° C, a layer of stainless steel pipe 850 ° C. The outer diameters of the reduced pipes are Φ Φ 8.1 mm and 6.5 mm. The selection of tube heaters depending on operating conditions and the purpose of the heater.


    In addition to the above mentioned, the basic elements, heaters comprise electrical and mechanical connections that are selected depending on the method of installation and connection of the heating element to the network. Electrical connections or contacts are usually steel, nickel-plated. Mechanical connectors are nipple, flange when required sealing and tin plates when it is stipulated that the heater works in liquids. We have a wide range of connections in our warehouse materials.
