What RIGGENBACH does

Riggenbach AG is a Swiss specialist contractor that plans, builds, and maintains ventilation, air conditioning, refrigeration, and energy technology systems for commercial, industrial, and public buildings across Switzerland. The company serves six primary verticals — industry and commerce, healthcare, office/administration, hospitality, retail/leisure, and residential construction — with project-based engineering, installation, and 24/7 service. Its competitive differentiator is vertical integration through in-house sheet metal production: Riggenbach fabricates its own ductwork, apparatus, and air outlets, processing roughly 380 tonnes of galvanized steel plus stainless steel and Peraluman annually across its 2,300 m² production hall. A 1,500-watt laser welding machine installed in May 2024 has accelerated custom component production by approximately 4x versus TIG welding.

The company operates from three Swiss branches (Olten headquarters, Brugg, Solothurn) with roughly 160 employees, 46 service vehicles, and a 24/7 emergency hotline. Riggenbach combines engineering, production, assembly, refrigeration/energy technology, and building automation (MSRT) under a single-source delivery model, and is SQS-certified for refrigeration systems up to Category III per DRG 2014/68/EU. Revenue is generated through project-based professional services for new construction and renovation, supplemented by recurring maintenance contracts with 1,500 service customers. Named anchor clients include F. Hoffmann-La Roche AG, Coop (30+ year relationship), Lindt & Sprüngli, Siegfried AG, R. Nussbaum AG, Lidl Schweiz (57 stores), Fondation Beyeler, Kernkraftwerk Gösgen (35+ years), and Paul Scherrer Institut (25+ years).

Riggenbach became a wholly-owned subsidiary of Burkhalter Gruppe on June 29, 2023, gaining access to broader building-technology capabilities while retaining its brand, locations, and contracts. Lukas Probst succeeded Peter Eggimann as CEO effective January 1, 2024, with further leadership expansion in January 2025 adding Tobias Rudolf von Rohr and Thomas Pfeiffer to the Geschäftsleitung and Isabelle Gut to the extended management. Annual revenue is approximately CHF 40 million.
