HILLER develops and manufactures decanter centrifuges and solid-liquid separation systems – from controls to system engineering.
Hiller GmbH
VilsbiburgNew on Amplifa
Separation technology from Vilsbiburg since 1971
Hiller GmbH, based in Vilsbiburg, has specialized since 1971 in the development, design, manufacturing and distribution of decanter centrifuges for solid-liquid separation. The product range includes the DecaPress and DecaTec decanter centrifuge series, compact systems (DecaSmart), the SEE-Control pro control technology as well as turnkey system installations from planning to commissioning. HILLER has manufactured its own hydraulic drives since 1980 and its own decanter gearboxes since 2010 – as one of the few decanter manufacturers with in-house drive production. The systems are used mainly in environmental and wastewater technology, the food and beverage industry, mining and tunneling, the oil and gas industry, and the chemical, process and pharmaceutical industries. The company, with more than 200 employees, has delivered over 7,000 centrifuges to more than 30 countries and has been part of the Ferrum Group since 2018. The portfolio is complemented by service, maintenance, retrofit, rental systems, testing technology and in-house laboratory analyses.
