Hydraulics specialist for power units, systems and service
Knoll Hydraulik GmbH & Co. KG is a specialist in custom hydraulic power unit construction and individual hydraulic systems for plant engineering. Its range of services covers engineering and design (CAD, 3D with SolidWorks, ePlan Fluid, ELCAD), manufacturing, hydraulic and electrical assembly, piping installation, wiring, commissioning, and test bench construction for flow, pressure, pulsation, endurance, high-pressure and burst pressure testing. This is complemented by manufacturer-independent repair and overhaul, maintenance, troubleshooting, fluid management including oil analysis and oil cleaning, component trading, control and drive technology, as well as training. As an official Bosch Rexroth sales and service partner (since 1978, Certified Excellence Partner since 2020), the company produces more than 1,200 units in-house per year. The group employs over 90 staff at four locations in Germany and Austria and generates a group-wide revenue volume of around 17 million euros. The headquarters are in Bindlach near Bayreuth; further locations are Chemnitz-Röhrsdorf, Unterschleißheim and Langenrohr (Eurofluid Hydraulik GmbH, Austria).
