January 2024 – extrutec GmbH

The new heating concept developed by extrutec (EHKO), consisting of an electrically resistance-heated base heating system in combination with an inductive taper, has already been sold to the first customers Purso and Mäkelä from Finland. To test the new concept, a test zone consisting of a 2.5-meter-long segment for 12-inch logs was set up and put into operation at the Menden site. The first series of tests are very promising and confirm the previously simulated data. The heating output of 280 kW is realized via resistance-heated heating registers. The test zone will be available for customer demonstrations next February from 21st February to 29th of February 2024 (week 8 and 9). Heating tests and control behavior will be demonstrated, and there will also be the opportunity to visit the production facility for induction systems at the Menden site. If you are interested in a visit, our sales manager Ulrich Bucher will be happy to answer your questions and arrange an appointment.

Successful EHKO-Customer Inhouse Event:

The Showing of our electrically resistance-heated highspeed convection oven (EHKO) was a highlight of the event

We cordially invited you to our EHKO customer event at our new location in Menden, Germany. The main highlight of the event was the prototype of our newly developed electrically resistance-heated high-speed convection oven (EHKO), which had already been operating successfully there for several weeks.

Heating tests and the control behavior of the EHKO test zone were demonstrated. Additionally, visitors had the opportunity to explore the production of induction systems and the operations of our subsidiary TCT Induktionstechnik at the Menden site.

extrutec's newly developed heating concept (EHKO), consisting of an electrically resistance-heated base heating system in combination with an inductive taper, was successfully sold to the first customers, Purso and Mäkelä from Finland. To test the new concept, a test zone consisting of a 2.5-meter-long segment for 12-inch bars was set up and put into operation at the Menden site. The first test series were very promising and confirmed the previously simulated data. The heating output of 280 kW was achieved via resistance-heated heating registers.

Purso becomes first customer to buy newly developed EHKO-heating furnace

The extrutec long term customer Purso oy from Siuro Finland is widely known for their aluminum profile production of sustainable solutions for a wide range of uses from industrial applications and building facades to lighting. The company pursues an ambitious goal to reduce their CO₂ emissions with every new investment.

extrutec will deliver the new EHKO heater with hot log saw as a replacement for an old gas fired furnace. The installation will start at the beginning of 2025. Purso is the first customer worldwide to buy such a heating system.

Mäkelä becomes the first Inline-EHKO customer

The production line modernization of Mäkelä Alu in Finland will reduce its co2 emission by 960 tons. This is made possible by the complete electrification of the heating process. The so called electrically heated high speed convection furnace (EHKO), developed by extrutec, combines the highest possible energy efficiency with a pure electrical heating source. Special about the EHKO für Mäkele is the patented Inline-Version. This combines the resistant heated base heating with a directly connected induction oven. This saves additional energy and is extremely space saving, in that way that old gas/LPG furnaces can be replaced without major modifications of the equipment setup.
