What Zehnder Group does

Zehnder Group AG is a Swiss publicly listed indoor climate solutions provider founded in 1895 and headquartered in Gränichen, Switzerland, with shares trading on the SIX Swiss Exchange under ticker ZEHN and the founding family retaining majority control. The company operates across four product lines: comfortable indoor ventilation systems with up to 96% heat recovery (ComfoAir Q, ComfoClime, ComfoConnect gateways), decorative radiators including the Studio Collection premium line, heating and cooling ceiling systems for large spaces, and industrial air cleaning solutions with smart monitoring. Underlying technology combines proprietary heat and moisture recovery, radiant ceiling panel engineering, and cloud connectivity for system monitoring. Zehnder operates 16 production plants and serves customers in 70+ countries through local sales companies, an academy-trained installer network, and a portfolio of 12+ acquired regional brands including Acova, Caladair, CORE, Enervent, Filtech, Greenwood, Siber, Lifebreath, Rittling, Runtal, Fortuneway, and Nather.

Revenue is generated almost entirely through B2B hardware sales of ventilation units, radiators, climate ceilings, and air cleaning systems, with FY2025 group revenue of EUR 760.7 million (ventilation 66%, radiators 34%). Pricing is project-based and quote-driven through regional sales contacts, with the company targeting commercial, residential, and industrial end markets via direct enterprise sales, channel distributors, and installer partners. The company trained 25,000 installer customers in 2025 and employs approximately 3,500 people globally, with FY2025 adjusted EBIT of EUR 65.2M (8.6% margin) and operating cash flow of EUR 80M. Active M&A in ventilation (notably the EUR 86M Siber acquisition in 2024) is accelerating the company's strategic pivot away from its legacy radiator base.
