Extensive expertise in hydropower plant technology
Hydraulic steel structures
In hydraulic steel structures, durable and high-quality hydraulic systems are required for the gates, weirs and intake gates. Using standard components, we supply these to you cost-optimised in the tried-and-tested HYDAC quality. As one of the few providers worldwide, we offer you – in addition to cylinders to DIN ISO 19704 – large cylinders with up to 20 m strokes. Take advantage of our extensive portfolio.
Shut-off devices ensure the safe operation of your hydropower plant. Mechanical-hydraulic control devices manage the high pressure of the water masses and allow for short, safe closing times. HYDAC supports you with highly functional cylinders in accordance with AD 2000 and DIN ISO 19704. Our decades of experience in hydraulics, process filtration and accumulator technology make us your perfect partner.
Whether it's Kaplan, Francis, Pelton or pump turbines - HYDAC produces custom system solutions with standardised components for your turbines. In addition to hydraulic turbine controllers, which are essential for controlling the adjustment components of a turbine, we impress with our efficient accumulator solutions and expertise in process water filtration (e.g. shaft seals). Thanks to our international service, we are able to provide consultations on-site.
The energy converter in the hydropower plant: driven by turbines, the generator uses the water's kinetic energy and converts this into electric energy. Its functionality must be guaranteed at all times. An optimal oil supply for lubrication and cooling makes a significant contribution to safe system operation. HYDAC provides comprehensive advice on solutions for lifting, braking and cooling systems as well as lubricating oil systems.
Balance of Plant
The auxiliary functions have a significant influence on the productivity of your hydropower plant. It's not just the monitoring of the most important parameters via condition monitoring that plays an important role here, but also the extensive inspection, treatment and filtration of operating fluids. Rely on our expertise as a specialist in hydraulics and fluid technology – since 1963.
