WULFF & UMAG Energy Solutions

What WULFF & UMAG Energy Solutions does

WULFF & UMAG Energy Solutions GmbH is a privately held German manufacturer of custom industrial boiler systems, headquartered and operating from a single facility in Husum, Schleswig-Holstein. The legal entity was incorporated in 2014, consolidating two Husum-based boiler builders — WULFF (founded 1932) and UMAG (founded 1979) — that merged in 2007. The company designs, engineers, and manufactures a portfolio of six core product lines: single-drum and two-drum water-tube boilers (up to 150 t/h, 120 bar, 550°C), smoke-tube boilers (5–60 t/h), waste heat / heat recovery boilers (1–50 MWel, up to 120 bar), hot water boilers (30–200 MW), and the Garant FSB 500/600 packaged quick steam generator, all supplemented by bespoke "Individual Solutions" engineering. Customers span district heating utilities (multiple Stadtwerke), industrial manufacturers (Airbus, Dow, BASF, Cargill, Hamburger Containerboard, British Sugar, Arla, Kerry), and gas turbine CHP operators across at least 16 countries in Europe, the Middle East, and South Asia.

Products and services

• Single-Drum Water-Tube Boiler Single-drum water-tube boiler designed for high steam parameters where conventional smoke-tube boilers cannot deliver required performance. Features natural water circulation, quick load change response, cleanable heating surfaces during operation, and capacities up to 150 t/h, 120 bar, and 550°C. Targeted at industrial manufacturers and energy utilities needing high-efficiency steam generation.
• Two-Drum Water-Tube Boiler Two-drum D-type water-tube boiler for medium steam parameters, featuring stable natural flow water circulation, high pre-manufacturing content with pressure testing in the workshop, and individually placeable superheater stages. Available in single or two-pass design and can also function as a waste heat boiler. Rated up to 100 t/h, 50 bar, and 550°C. Targeted at industrial steam users and OEMs.
• Smoke-Tube Boiler Smoke-tube boiler with cooled or dry combustion chamber for small to medium pressure ranges and steam outputs. Features large water content for short-term steam supply during pressure drops and can be combined with superheaters, economisers, and additional heating surfaces. Suitable for downstream gas turbines of 1-15 MWel, with steam outputs from 5-60 t/h at up to 40 bar. Targeted at smaller industrial steam users and CHP operators.
• Waste Heat Recovery Boiler Waste heat recovery boiler for gas turbines, motors, and thermal processes, designed for small- and medium-sized gas turbines, reciprocating engines (especially gas motors), thermal treatment plants, and waste heat from various processes. Enables efficient utilization of waste heat streams at 1-50 MWel, 5-100 t/h, up to 120 bar. Targeted at CHP operators and industrial plants with waste heat sources.
• Hot Water Boiler Hot water boiler in water-tube design with forced water flow for large heat loads and high hot water parameters. Features high boiler efficiency, solid durable construction, flexible operation options, and adjustable sizing for restricted site conditions. Compatible with various waste heat applications. Rated 30-200 MW heat load, 70-250°C, up to 40 bar. Targeted at district heating utilities and large industrial facilities.
• Individual Custom Boiler Solutions Custom-engineered boiler solutions tailored to specific customer requirements and plant conditions, considering fuels, parameters, boiler operation modes, restricted space, difficult erection sequences, exhaust gas and noise emission requirements, tight time schedules, and special site conditions. Targeted at industrial customers whose process requirements cannot be met by standard products.
• Garant FSB 500/600 Quick Steam Generator Saturated steam generator with adjustable steam output between 500-600 kg/h, operating pressure range 8-31 bar. Compatible with natural gas L or H, light fuel oil, or combination burners. Features large combustion chamber for low-NOx operation below legal emission limits. Efficiency up to 95.6% with downstream economiser. Manufactured per DIN EN 12952. Targeted at small industrial and commercial steam users needing a standardized rapid-delivery steam solution.
• Assembly, Commissioning, and After-Sales Service End-to-end project delivery services including cold checks, function tests, hot commissioning with control loop checks, performance tests, operator training, and post-handover after-sales support. Includes service contracts, repairs, maintenance, spare parts supply, and full-service maintenance contracts for both WULFF & UMAG-produced and third-party boiler systems.
