SIEGLE + EPPLE has grown from a small craft business with five employees, founded in Feuerbach in 1922 by Wilhelm Siegle and Friedrich Epple, into today's company, which now has more than 700 highly qualified, motivated employees and is one of the most efficient companies in building services engineering, particularly in ventilation and air conditioning technology.
The following milestones demonstrate what we have achieved in the past – but they also mean that we see the future and its challenges as an opportunity to improve what we already have a little bit every day, as well as to develop and enable new things – for ourselves and our business community, for our customers and business partners!
A total of 15 full air conditioning units for outdoor installation were delivered to the US Klinikum Weilerbach construction project with the special feature of a completely plug-and-play design including media modules, piping, control cabinets, and control systems. Cross-departmental planning and complete pre-assembly at our Heimerdingen plant ensured quick installation and commissioning on site.
With the launch of a dual study program, SIEGLE + EPPLE is creating new prospects for training young talent. In doing so, we are sending a clear signal for promoting young talent, practical relevance, and securing our technical expertise in the long term.
