More Information


Andreas Egelseder has been chairman of the management board of LTG Aktiengesellschaft since November 1, 2021. He is responsible for sales of Comfort Air Technology and Process Air Technology, the commercial area and production. For many years, he was responsible for sales, marketing and business development at Felss Gruppe GmbH in Königsbach-Stein, most recently for sales and marketing at SMC Deutschland GmbH in Egelsbach.

Ralf Wagner is member of the management board and CTO. He joined the company in 1994 as a development engineer after studying aerospace engineering and took over as head of the research laboratory and the Comfort Air Technology development department in 1999. Since 2008 Mr. Wagner has been responsible for the entire area of engineering services and development for Comfort Air Technology and Process Air Technology. He is personally involved in many of LTG Aktiengesellschaft’s numerous inventions and patents and represents the company in various standardization committees and association bodies such as DIN and the FGK.





Supplying workplaces with fresh air and improving process conditions in companies was a pioneering task of LTG’s founder, Dr. Albert Klein. After his return from the USA, he founded the company “Cärrier Lufttechnische Gesellschaft Dr.-Ing. Albert Klein” in Stuttgart in 1924, initially as an engineering office for ventilation technology, which was largely unknown in Europe at the time. The first systems were realized in applications where a uniform climate led to noticeable savings in the production process, e.g. in the automotive, tobacco and later textile industries.

From the 1930s onwards, LTG expanded its business area of planning and installing innovative ventilation technology with its own production facilities. Both the product portfolio and the customer base in Europe were successfully expanded and, in addition to process air conditioning, more and more room air conditioning systems were installed, often using the induction principle developed by Dr. Klein. In the post-war years in particular, LTG grew by rebuilding or constructing new factories and administrative buildings. Engineering services, the root of the company, have been a separate business segment since 1993. The in-house laboratory is a solid basis for research and development and over 50 patents are an expression of the company’s innovative strength. In 1999, all product and development activities were bundled in LTG Aktiengesellschaft.

The company is still active on the global market today with high-quality products and customized solutions for room and process air. The core products are air-water, air diffuser and air distribution systems, fans in all common designs as well as filter and humidification systems. The main areas of application are room air conditioning, e.g. in offices, hotels, schools, museums and hospitals, but also in passenger ships, trains and other special uses as well as industrial applications in thermal, process engineering or material recovery processes and wind simulations.
