Hiller GmbH

Hiller GmbH, operating as HILLER Dekanterzentrifugen and Trenntechnik, is a German manufacturer of decanter centrifuges and separation technology based in Vilsbiburg, with over 50 years of experience and more than 7,000 centrifuges delivered worldwide to installations across 30 countries. The company's flagship DecaPress decanter centrifuge line handles two-phase and three-phase separation across a throughput range of 0.5 to 150 cubic meters per hour, generating centrifugal forces up to 4,000 times gravity. DecaPress units feature ATEX-compliant and hygienic design options, proven wear protection, compact footprint, and minimal polymer or flocculant requirements while achieving high dry solids content in the discharge. The DecaTec line addresses specialized process requirements with adapted construction, while the DecaSmart provides a compact option for smaller-scale applications. A standout technology is Hiller's Lysate system for sewage sludge disintegration, which reduces sludge viscosity by up to 40 percent, improves dewatering performance, increases biogas yield from anaerobic digestion, prevents recirculation of contaminated cell water, and reduces foam formation in the digester. Process control is managed through the SEE-Control pro system, which provides intuitive operation, precise process monitoring, and smart integration into existing plant infrastructure. Hiller provides turnkey project management from design through commissioning and offers rental and pilot testing programs for pre-deployment validation. Industries served include municipal and industrial wastewater, food and beverages, mining and minerals, oil and gas, and chemical, process, and pharmaceutical manufacturing.
