Seven-Air has relied on Switzerland as a production location since the company was founded in 1971. The high level of vertical integration at the Hitzkirch plant with the processes of sheet metal working, powder coating, insulation, housing frame production, unit and electrical assembly is unique for Swiss air conditioning unit manufacturing. So that the specialist knowledge learned in the theory room also has a practical relevance, the participants of the Air Conditioning Academy therefore decided to broaden their horizons with an insight into Seven-Air. Our project manager for refurbishments and also a participant in the Academy of Air Conditioning Technology, Roger Trösch, guided the 11 participants through our state-of-the-art production and drew their attention to crucial details.
