What LTG does
LTG Aktiengesellschaft is a 100-year-old German air-technology manufacturer headquartered in Stuttgart with production in Weil der Stadt and a wholly-owned US subsidiary (LTG Incorporated) in Spartanburg, South Carolina. The company operates two divisions: Raumlufttechnik (room air technology) supplying air-water systems, air diffusers, and air distribution solutions for building climate control, and Prozesslufttechnik (process air technology) supplying fans (cross-flow, axial, and radial), modular filter and humidification systems, and airstream simulators for industrial applications. Its core engineering competencies include high-efficiency fan design (up to 89% efficiency), aerodynamic impeller and housing development for low-noise operation, and 300+ reference wind-tunnel airstream simulator installations serving WLTP, RDE, SC03, CFR §1066, and WMTC vehicle testing programs. The product portfolio is supported by in-house testing and development in Zuffenhausen and spans standardized series (VQS, VQC, VQ, VSR, VRS, VRK, VAN, VAR, VAH) as well as customized engineered systems.
The company serves industrial B2B customers across automotive (emissions/aerodynamic test labs and OEMs), printing and paper, textile/nonwoven, and commercial/residential building HVAC. Its go-to-market is sales-led: direct sales teams and technical consultants in Germany and the United States, complemented by 20 country representations through international sales partners. Revenue is generated primarily through one-time hardware sales of equipment and custom-engineered system solutions, with pricing handled via individual quotation on multi-year contracts rather than public list pricing. The company holds DIN EN ISO 9001:2015 certification (TÜV Süd, valid through November 15, 2027) and co-founded the 'Fan Replacement Makes It Efficient' industry initiative to promote energy-efficient fan retrofits.
LTG is structured as an independent German Aktiengesellschaft with no identified parent, venture capital, or private equity investors. Leadership is led by CEO Dipl.-Ing. Andreas Egelseder and Supervisory Board Chairman Dr. Franz Wimpffen. Across its three sites the company employs approximately 160 people (per scale commentary), operating as a stable, privately-held Mittelstand industrial manufacturer with multi-decade customer relationships and a regulated, project-driven revenue model.
