LTG’s founder, Dr. Albert Klein, was a pioneer in systems for supplying workplaces with fresh air and improving process conditions in factories. In 1924, upon his return from the USA, he founded the company Cärrier Lufttechnische Gesellschaft Dr.-Ing. Albert Klein in Stuttgart: at the outset this was an engineering consultancy concerned with air processing, a technology about which very little was known in Europe. The first systems for creating a uniform climate led to significant savings in production processes. They were initially put to use in the automotive and tobacco industries, and later also in the textile industry.
In the 1930s, LTG expanded its operations: in addition to planning and installing innovative air-processing systems, it began to manufacture products of its own. The company was successful in enlarging its product range and broadening its customer base in Europe. Besides installing air-conditioning for industrial processes, it increasingly provided room air-conditioning systems, often based on the induction principle developed by Dr. Klein. In the years after World War II, LTG experienced swift growth thanks to reconstruction and the building of new factories and administrative buildings. In 1993, the company’s original area of activity, engineering services, became a separate business segment. The in-house laboratory now provides a solid foundation for research and development, with more than 50 patents testifying to the company’s innovative prowess. In 1999, LTG’s product and development activities were combined under the umbrella of LTG Aktiengesellschaft.
Today, the company is active throughout the world, providing high-quality products and customised solutions for room air and process air. Its core products are air/water, air diffuser and air distribution systems, fans of all types, and filtration and humidification systems. The main areas of application are air-conditioning in offices, hotels, schools, museums and hospitals, plus special areas such as passenger ships and trains, while industrial applications include thermal engineering, process engineering, recycling and wind simulations.
