Electric heat made in Döbeln: there’s no such thing as “impossible”!
Döbeln Elektrowärme GmbH (DEW) is a full-service provider for the development and manufacture of electric heating elements. From tubular heaters to cartridge heaters and panel heater elements: our products and solutions have been used for decades wherever safe and efficient heating is required. At DEW, we build on a tightly interwoven combination of engineering services and our own production facilities on the one hand, but also on a high vertical range of manufacture with our own tool making facilities and an industrial measurement laboratory on the other. This enables us to offer precisely what the market wants: individual components that are ready to install and include all the necessary control systems. With a state-of-the-art range of machinery, excellent delivery reliability and a genuine spirit of innovation at the heart of everything we do, we are a reliable supplier for customers in all industries.
Competences
Our development activities include, among others, construction design and power calculations. The starting point for this is an intensive consultation and analysis phase.
The heating elements are wound into a spiral coil so that the maximum power can be accommodated in a compact space. The pipe jackets are cut to size at the same time.
The heating coils are paced in the stainless steel tubes. Spaces in between are filled with an insulating material made of magnesium oxide.
In our rolling mills the filled heating elements are densely compacted. In the annealing furnace the rolled tubular heating elements are recrystallized prior to further processing.
The heating elements are given their final shape. There are many designs here: from the classical “U” or “W” shapes to the three-dimensional spiral shapes familiar from immersion heaters.
The tubular heater can be fitted with flanges or threaded bushes at the ends for easy mounting or screw fitting in boilers, housings or containers.
Due to the pronounced hygroscopic properties of the magnesium oxide, the tubular heaters are sealed with a special temperature and moisture seal.
Based on the customer requirements, this is where the correct preconditions for the electrical connections are created – e.g. with threaded connections, welded-on blade connectors, cables and terminals.
Final assembly of the component assemblies is performed based on the design drawings – including electrical wiring, the terminal box with control systems and screwed cable glands.
As a company that is certified to ISO-9001, we not only carry out final checks but ensure that the quality is up to standard all the way along the entire process, from the receipt of incoming goods to the dispatch and shipping of goods.
This is where our heating elements are readied for dispatch: DEW supplies directly to customers throughout the whole of Europe and indirectly – arranged by customers – also to the USA and the Middle East.
In order to make the tubular heaters, we need auxiliary tools for processes like bending, shaping and welding. For small-scale applications we manufacture these in-house ourselves.
Statistical checks are performed for the heating elements in the laboratory. In addition, we can also carry out customer-specific tests for new developments here.
Our DEW instantaneous heaters are installed in heat pumps from renowned manufacturers.
The newly designed high rack warehouse ensures fast and effective picking of materials for production orders.
A century of competence in electric heating
The history of DEW reaches back to the 1920s. The company was founded by engineer Emil Schuppang in 1922 as a manufacturer of, among other things, electrical devices for the heating of household appliances. In the decades after the war, the structure and product portfolio varied according to the planned production targets that were set by government. As a nationally-owned company, VEB Elektrowärme Döbeln and its affiliated companies employed up to 640 employees, and it was the sole manufacturer of heating elements in the former East Germany. In 1991 the core company was sold by the Treuhandanstalt, the Trust Agency appointed with the task of privatising the publicly-owned enterprises in East Germany, and it has operated since then under the name Döbeln Elektrowärme GmbH with the same range of products and services.
Certified quality from Döbeln
Quality is not something you can just measure. But it is something you can craft if you put the right processes in place. This is why DEW trusts in uncompromising quality management on the basis of the requirements of DIN EU ISO 9001: 2015. In addition, external UL auditors check our processes every six months to examine them with regard to the specific requirements for products for export to Canada and the USA. As a RoHS-compliant company, we also ensure that the requirements of the EU directive that restricts the use of hazardous materials in electrical equipment are met.
Jobs with long-term prospects
Fair pay, an informal working atmosphere and long-term prospects: DEW offers secure jobs to skilled professionals with and without a background in engineering in the Döbeln region. We are a medium-sized company supplying to customers in important growth industries. We have a rock solid business model and are firmly established in the market.
