What BBS does

BBS GmbH is a German industrial boiler manufacturer specializing in custom-engineered steam boilers, hot water boilers, thermal oil systems, marine/offshore boilers, waste heat recovery systems, and biomass furnaces. The company was formed in summer 2004 through the merger of BAY Wärmetechnik GmbH and Bay Engineering and Consulting, with operational heritage tracing back to predecessor entities active since approximately 1959. Headquartered in Freiberg am Neckar, Germany, BBS produces equipment ranging from 50 kg/h to 25,000 kg/h steam capacity, with operating pressures up to 120 bar, temperatures up to 400°C, and thermal oil outputs up to 16 MW. Its proprietary engineering covers three-pass flame tube boilers, water tube boilers, composite marine boilers that recover ship engine waste heat, fluidised bed furnaces paired with pyrolysis reactors, and TÜV-approved containerized boiler plants.

The product portfolio spans six categories: steam boilers (50-25,000 kg/h, up to 120 bar), hot water boilers (100 kW-35 MW, up to 300°C), thermal oil systems (0.1-16 MW, up to 420°C), marine and offshore boilers certified by Germanischer Lloyd, Lloyds Register, and RMRS, biomass furnaces (0.5-50 MW), and ancillary plant equipment including heat exchangers, economisers, flues, electrical control systems, and steam tanks. Customers include automotive manufacturers (Audi Hungary, VW Slovakia), hospitals (Kliniken Ludwigsburg-Bietigheim, Carl Gustav Carus University Hospital Dresden), oil and gas operators (CNOOC, Lukoil, Transbalt), food processors (Universal Robina, Santa Bremor, BEWEKA), marine operators (BLS AG, Russian fishing fleets), and energy/biomass projects (Bauer Holzenergie, FLLC VMG Industry).

BBS operates a direct enterprise field sales model with no distributor or reseller network, supported by a multilingual website (German, English, Russian). All sales are quote-based with multi-year project contracts; no public pricing is disclosed. Revenue is generated from three streams: industrial boiler equipment sales (one-time, project-based), complete boiler plant engineering and installation (professional services), and aftermarket services and spare parts. The company employs 11-50 people and is privately held with Rudolf Schwarzenberger as Managing Director; no outside investors are identified. International project reach spans Russia, China, CIS countries, Southeast Asia, and Europe.
