BMS Energietechnik

What BMS Energietechnik does

BMS-Energietechnik AG is a Swiss privately held engineering and systems company founded in 1985/1986 by Remo Meister and headquartered in Wilderswil, Canton of Bern. The company designs and supplies energy-efficient systems and components for refrigeration, air conditioning, heating, and industrial heat-recovery applications, with strong emphasis on waste heat utilization, two-stage evaporation thermodynamics, and plate heat exchanger engineering. Its core commercial product lines are the patented BMS power® modular technique (P200/P400 modules developed with HSR Hochschule für Technik Rapperswil) and the eXergiemaschine family (eXm-pro, eXm-compact, eXm-max at 100 kW, plus a remote-monitoring add-on) co-developed with German partner varmeco GmbH & Co. KG. Supporting products include waste-heat utilization systems (pipe-, wall-, enclosure-, and collector-mounted), brazed and gasketed plate heat exchangers, buffer and domestic hot water storage (300–5,000 L), latent heat storage, instantaneous fresh-water stations for legionella-safe hot water, air-cooled condensers/recoolers, and micro-bubble air separators.

The company makes money through three streams: (1) hardware sales of engineered systems and components; (2) engineering services covering calculations, system sizing, commissioning, and operational testing (including the FWS eXm commissioning program); and (3) education and training via courses, events, and presentations. It operates a regional distribution structure in Switzerland (HQ in Wilderswil, branch in Bulle for French-speaking Switzerland, representation in Ticino through THERMOZENITH SA) and a network of roughly 30 specialists inside the broader "BMS-Netzwerk" encompassing tier-1 component suppliers (Alfa Laval, Danfoss, Grundfos, Kelvion, SWEP, Beijer Ref), academic partners (HSR Rapperswil, HSLU Luzern, ETH Zürich, Berner Fachhochschule), and policy partners (EnergieSchweiz, energie-cluster.ch, Innosuisse). Ownership remains with founder Remo Meister and his wife Heidy; Roman Aebersold has led day-to-day operations since 1999 and as Managing Director since 2014, with Edward Nijgh as Chairman of the Board.
