What Buttner does
Siempelkamp Energy & Drying Solutions GmbH, operating under the historic Büttner brand until its 2025 rebrand, is a German engineering company founded in 1874 and headquartered in Krefeld, with a wholly-owned subsidiary structure under Siempelkamp Group since 1995. The company designs, engineers, supplies, installs, and services industrial drying systems, energy systems, multi-fuel burners, and emission-control equipment for global industrial customers in wood-based panels (MDF, OSB, particleboard, insulation boards), wood pellet production, biomass processing, sugar, animal feed, starch, and other bulk solids, claiming more than 2,030 installed plants across 52 countries.
Its core product portfolio comprises rotary drum dryers (trommeltrockner), tube bundle dryers (röhrenbündeltrockner), flash tube dryers (stromrohrtrockner), and belt dryers (offered in cooperation with Swiss Combi since 2023); energy systems including grate-firing combustion, steam generators, finned-wall boilers, and thermal oil heaters; combination and line burners for dust, gas, and oil; and wet and dry electrostatic precipitators developed in-house at the Kaiserslautern environmental technology competence centre established in 2022. The product mix is project-engineered for each customer, with completion scope from process engineering and supply through installation, commissioning, and after-sales service, modernization, and training.
The company monetizes through custom turnkey plant sales (hardware) on multi-year contracts, complemented by recurring spare parts, remote and field service, modernization/rebuild orders (including non-Büttner plants), and academy training. It sells via direct enterprise field sales supported by wholly-owned subsidiaries in the US (Charlotte), Brazil (Curitiba), Singapore, and Australia (Brighton), plus channel partners in Spain/Portugal, France, and Turkey, and maintains a 51-100 employee base with headquarters in Krefeld, a branch in Hanover, and the Kaiserslautern R&D centre.

Buttner competitors and assessment
Company assessmentBroad incumbents
- Bühler Group: Large-scale process technologies and plant engineering for feed, food and bulk materials. Overlaps with Büttner in animal-feed drying applications (DDGS, beet pulp) though Bühler operates much broader across the food value chain.
- Atlas Copco: Broad industrial equipment group with compressor and process-gas solutions that intersect with industrial drying air systems and emissions-handling equipment. A larger incumbent with overlapping but non-identical scope.
Direct peers
- GEA Group: Engineered process equipment and drying systems serving food, feed, and bulk-solids industries. Directly comparable in industrial drying technology and serves overlapping customer segments including feed and starch processors.
- Valmet: Supplier of process technologies, machinery and aftermarket services for pulp, paper and energy. Competes in wood-based-panel adjacent process lines and in biomass-fired energy systems serving similar industrial customers.
- ANDRITZ: Global supplier of industrial drying, separation, and pulp/paper processing equipment. Competes directly with Büttner in industrial drum and belt dryers and supplies biomass energy systems — the closest like-for-like competitor across the drying and energy portfolio.
- Thermax: Industrial boiler, steam generator and energy-systems supplier with strong biomass/heavy-oil fired equipment portfolio. Directly comparable in industrial steam generation, thermal-oil heaters and combustion systems.
- Dieffenbacher: Turnkey plant supplier for wood-based panels (MDF, OSB, particleboard). Competes directly with Siempelkamp Group on complete greenfield panel plants, including drying, forming, pressing and finishing lines.
- Swiss Combi: Swiss manufacturer of belt dryers and bulk-material drying systems. Both a strategic cooperation partner (belt dryer segment) and a competing specialist in gentle-material drying for biomass and bulk-solids applications.
Emerging players
- Munters: Specialist in air-treatment and humidity-control solutions for industrial applications including paper and biomass drying. Adjacent competitor in process-air dehumidification and drying-system technology.
- Cotes International: Smaller specialist in industrial adsorption dryers and dehumidification for industrial processes. Addresses a narrower niche but competes in process-air drying applications overlapping with Büttner's environmental-technology portfolio.
