What Satek does

Satek GmbH is a German specialty manufacturer of complete sanitary wet cell systems for rail vehicles, headquartered in Salach, Kreis Göppingen, Baden-Württemberg. Founded in September 2004, the company designs, develops, and produces modular WC cabins (standard, universal, and TSI PRM wheelchair-accessible variants), door systems (revolving and the proprietary Samove sliding door), tank systems with bioreactor wastewater treatment, grey water and fresh/waste piping, convection and surface heating, and rail-specific accessories such as the patented PRM folding support handle, IR-sensor taps, and the Sambino baby care line. Underlying technology is mechanical and industrial — CNC-machined stainless steel and PE assemblies, certified adhesive bonding (DIN 6701-Class A2) and welding (DIN EN 15085-2 CL4) — supported by an IRIS Rev.03 / ISO 9001 / ISO 14001 quality stack and an in-house PDM/ERP backbone.

Satek operates a B2B enterprise field-sales model, engaging directly with rail vehicle OEMs and operators as a strategic partner that assumes full system responsibility from development through after-sales service. Revenue is generated primarily through project-based hardware sales of complete cabins, subsystems, and individual components, supplemented by professional services (commissioning, maintenance, spare parts, retrofit, and training). The customer base is anchored by Siemens AG — across the Velaro high-speed platform (Eurostar e320, Turkey, BR 407), the ICx inter-city programme (over 2,400 cabins delivered 2013–2024) and the Sambino Seat co-development — with Bombardier Transportation as a co-supplier on ICx and Swiss operators SBB and BLS as additional references. Products are installed in rolling stock operating across Germany, Austria, Switzerland, the UK, France, Belgium, the Netherlands, Turkey, and China, with manufacturing and storage capacity of 5,500 m² supporting serial delivery to approximately 110 employees.
