What Zimmer & Hälbig does
Zimmer & Hälbig GmbH is a Bielefeld-headquartered specialist in technical building equipment (Technische Gebäudeausrüstung / TGA), operating across Germany since 1974 with approximately 330 employees and 6-7 regional offices. The company delivers HVAC-R systems (Heating, Ventilation, Air Conditioning, and Refrigeration) for technically demanding facilities including hospitals, laboratories, pharmaceutical cleanrooms, data centers, and industrial production sites. Its technical scope spans VRF and heat pump technology, air-handling and ventilation, refrigeration, MSR (measurement, control, regulation), and digital energy monitoring compliant with the German Energieeffizienzgesetz (EnEfG/GEG).
The business model combines one-time project-based revenue from turn-key planning, construction, and installation work — with individual projects reaching the multi-million euro range — with recurring service and maintenance revenue from a nationwide 24-hour service network covering maintenance, inspection, repair, and optimization. The company sells directly through its regional offices (Bielefeld, Osnabrück, Leipzig, Köln, Tuttlingen, Hannover) with no channel intermediaries, targeting enterprise and public-sector customers across healthcare, education, manufacturing, and government verticals.
As of July 31, 2025, Zimmer & Hälbig has signed an acquisition agreement with VINCI S.A., under which it would be integrated into VINCI Energies Building Solutions' network of 150 German business units, pending German competition authority approval. The transaction marks the end of 51 years of independent operation and positions the company to leverage VINCI's scale, procurement, and cross-referral capabilities while preserving its regional brand and management.
