What Hiller separation & process does
Hiller separation & process, legally Hiller GmbH, is a privately held German manufacturer of decanter centrifuges for solid-liquid and solid-liquid-liquid separation, founded in 1971 and headquartered in Vilsbiburg, Germany. The company is a member of the Ferrum Group, currently employs 200+ technical staff, and reports more than 7,000 centrifuges delivered across 30 countries. It serves five primary verticals: environmental technology and wastewater, food and beverage, mining and minerals, oil and gas/energy, and chemical/pharmaceutical/biotech.
The core product portfolio comprises three decanter lines — DecaPress (2-phase and 3-phase separation, up to 4,000 x g centrifugal force and 150 m³/h hydraulic throughput), DecaTec (next-generation industrial decanter for demanding applications including high temperatures and ATEX zones), and DecaSmart (compact plug-and-play system with integrated controls, pump, piping, and valves on a steel platform). These are supported by four proprietary drive options (DECA-DRIVE, FSG-DRIVE, HYDRAULICS, FULLY-HYDRAULIC, all available in ATEX versions), the SEE-Control Pro intelligent control system with Profinet and remote monitoring, tiered Quality Assurance Packages (QAP Basic/Certify/Evidence/Extended), and a mobile trial fleet of 20+ units (DP15 to DP764) for on-site pilots.
Hiller's revenue model combines one-time capital equipment sales (project-based pricing, e.g., EUR 860,000 for a DecaPress 574 system with peripheral equipment) with recurring service, maintenance, spare parts, retrofits, and mobile plant rentals. Distribution is hybrid: direct enterprise sales and two regional service offices in Germany, plus long-tenured channel partners — MSE Hiller (exclusive UK/Ireland, 25-year partnership, 200+ installed machines) and E3 Integrated Engineering (North America as "HILLER Systems by E3," 10+ years) — alongside a European mobile-unit partner network.

Hiller separation & process competitors and assessment
Company assessmentDirect peers
- GEA Group: German-based global mechanical and plant engineering group with a dedicated Separation & Flow Technologies division. GEA's decanter and separator portfolio overlaps directly with Hiller in dairy, food, wastewater, and chemical customers.
- Flottweg SE: German-headquartered manufacturer of decanter centrifuges and separation equipment based in Vilsbiburg-adjacent Bavaria. Highly comparable to Hiller on product line (2-phase and 3-phase decanters), end-markets (wastewater, food, chemical), and German-engineering positioning.
- Alfa Laval: Swedish industrial group and the global leader in separation technology. Alfa Laval's decanter centrifuge portfolio directly competes with Hiller's DecaPress/DecaTec across municipal wastewater, food, and mining applications, making it the most direct and largest comparable peer.
- Pieralisi: Italian manufacturer of decanter centrifuges with a strong specialty position in olive oil extraction (a segment Hiller also serves in Southern Europe) as well as broader industrial and wastewater applications. Directly comparable on product and end-markets.
- Centrisys Corporation: US-based manufacturer of decanter centrifuges focused on municipal and industrial wastewater, sludge thickening, and dewatering. A direct competitor with strong North American footprint, complementing Hiller's E3-led US push.
- Andritz Separation: Austrian-headquartered global supplier of solid-liquid separation equipment including decanter centrifuges. Competes head-to-head with Hiller in municipal and industrial sludge dewatering, food processing, and mining tailings applications.
Broad incumbents
- Tetra Pak: Switzerland-based global incumbent in food processing equipment with centrifugal separation solutions for dairy, beverages, and prepared foods. Broader portfolio than Hiller but overlaps materially in food & beverage customer accounts such as dairy and beverage processors.
- Veolia Water Technologies: Global water and wastewater services group that procures and integrates large-scale dewatering equipment (including centrifuges) as part of municipal and industrial turnkey projects. Adjacent — Veolia is a customer channel for upstream separation OEMs like Hiller rather than a manufacturer competitor, but materially shapes competitive procurement.
Regional players
- Mitsubishi Kakoki Kaisha: Japanese process equipment maker producing centrifuges and separation machinery for environmental, chemical, and food customers. Comparable technology with primarily Asian market focus; limited direct overlap with Hiller in Europe.
- Tomoe Engineering: Japanese manufacturer of industrial decanter centrifuges for wastewater, food, and chemical applications. Comparable on product but primarily serves Japan and Asia rather than directly competing with Hiller in Europe or the Americas.
