14 interested specialist craftsmen from the Netherlands visited the OEG at the Lienen production site from Friday to Saturday.
On Friday, the group started in the early afternoon with a tour of the tank production. All important and interesting production steps were explained live: from the automated winding of the stainless steel corrugated pipe and the heat exchangers, through the plasma cutter and welding stations, to the foaming of the high-quality insulation.
Then the solar and storage seminar started.
Here, the focus was primarily on the 4flex + ® heatpipe tube and hygiene tanks.
In addition to tips and tricks for installation on site, the most important quality features came up:
With a 20-year warranty on the solar tubes and a 10-year warranty on the OEG storage, the specialist tradesman stands out from the competition in customer talks.
All participants made intensive discussions and after the subsequent dinner they exchanged experiences late into the night.
