Depping

What Depping does

Depping AG is a Swiss privately held distributor and light-producer of ventilation and air conditioning accessories, headquartered in Zuchwil, Switzerland. Founded on 1 April 1993 by Dieter Lüthi and operated continuously since, the company maintains a catalog of approximately 3,000 SKUs spanning flexible hoses, flexible ventilation pipes, sound absorbers, flat duct systems, weather protection grilles, perforated and slot grilles, supply and exhaust valves, mounting accessories (clamps, ties, tapes), fire protection and shut-off elements, and the proprietary airTUBE controlled residential ventilation system for MINERGIE-compliant buildings. Products hold VKF/AEAI fire-safety certifications and are also offered as standardized BIM data through the Buildup platform for construction planning workflows.

The business is run from a single 2,500m² facility with 13 employees and serves an installed base of roughly 2,000 customers across Switzerland and select European markets. Go-to-market is a hybrid B2B and B2C channel mix: a direct e-commerce storefront for trade and individual buyers, wholesale distribution relationships, and direct sales to ventilation, HVAC, kitchen, and chimney installation firms. Reference projects cited include Prime Tower Zürich, Messeturm Basel, Diax Tower Zürich, Skyguide Dübendorf, and Migros Verwaltung Limmatplatz Zürich.

Revenue is generated almost entirely through one-time unit-priced product sales in Swiss Francs and Euros (standard terms: 2% discount within 10 days, net 30), with a blanket 3% price increase applied across categories effective 1 May 2024 to offset raw-material and transport cost inflation. The company is wholly owned by Dieter Lüthi and has no external investors, parent entity, or public listing.
