Extensive know-how in hydropower 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
Shut-off devices realise safe operation in your hydropower plant. Mechanical hydraulic control devices handle the high pressure of the enormous volumes of water and enable short, safe closing times. HYDAC can support you with highly functional cylinders in accordance with AD2000 and DIN ISO 19704. Our many years of expertise in hydraulics, process filtration and accumulator technology make us the perfect partner.
Water turbine
Whether it is a Kaplan, Francis, Pelton or pump turbine – HYDAC produces custom system solutions with standardised components for your water turbines. In addition to hydraulic turbine controllers, which are essential for controlling a turbine’s adjustment devices, we provide impressively efficient accumulator solutions and expertise in process water filtration (e.g. shaft sealing). Thanks to our international service, we are on hand to advise you wherever you are.
Generator
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 impact on the productivity of your hydropower plant. It is not only the monitoring of the key parameters via condition monitoring that plays a major role, but also the extensive observation, treatment and filtration of operating media. Trust our expertise as a specialist in hydraulics and fluid power – since 1963.
Sustainability
Sustainably save costs, despite constantly rising energy and raw material costs - HYDAC makes this possible thanks to standardised, installation space-optimised components and systems. We use optimised filter systems and drive systems to help you conserve resources in an efficient way. Reduce your CO2 emissions as well as the expenses for your hydropower plant in the long term.
Sustainability in hydropower plants: our product solutions
HYDAC KineSys variable-speed drive solution
Reduce the energy consumption, noise emissions, tank size and maintenance intervals of your hydropower plant? How is this possible? The variable-speed hydraulics paves the way for resource-conserving plant operation. With electromechanical cylinders, you no longer need to use oil as an operating medium, which lowers your contamination potential.
HYDAC Air-X filter technology
Save installation space with optimised degassing of your lubrication systems – thanks to the innovative Air-X technology from HYDAC. Reduce your tank size by up to 40 % and sustainably optimise your hydropower plant’s use of resources.
HYDAC dewatering unit FAM
Our FAM series dewaters, degasses and filters your hydraulic fluids and lubrication fluids. The efficient care means that you benefit from longer oil change intervals, reduced life cycle costs, greater reliability and increased system reliability.
HYDAC Varnish Elimination Unit
Are solid or gel-like deposits blocking your plant? Then your problem is oil degradation products, also known as varnish. The solution is our service-friendly Varnish Elimination Units, as they can reliably remove varnish from your mineral oils.
System availability
The trend towards digitalisation is everywhere and shows no signs of stopping, even in water power. HYDAC can support you on your journey with smart sensors and innovative monitoring devices for your systems and plants. With condition monitoring combined with predictive maintenance, we can reduce your servicing and maintenance intervals. Together we can increase the productivity of your large or small hydropower plant.
System availability in hydropower plants: our product solutions
HYDAC Contamination Sensor Module
To increase your system availability, use our impressive compact and cost-effective online condition monitoring module. Rely on our tried-and-tested technology for measuring solid particle contamination and water saturation in the oil-hydraulic systems in your hydropower technology.
HYDAC Metallic Contamination Sensor
The HYDAC MCS continuously measures the particle contamination in your fluids. The sensor detects critical machine states early on, so that you can plan maintenance accordingly. The MCS can optionally be switched between ISO 4406:1999 / SAE AS 4059 and ISO 4406:1987 / NAS 1638.
HYDAC IO-Link sensors
With Industry 4.0 in mind, we have added IO-Link and smart sensors to our range, which can do much more than just measuring. Benefit from valuable detailed information such as the overload situation, process value statistics, temperature profiles and operating hours. For reliable condition monitoring of your hydropower plants.
HYDAC p₀‑Guard pressure switch
Our reliable p0-guard monitors the pre-charge pressure of your hydraulic accumulators. This can increase the safety of your hydropower plants and enables gas leaks to be discovered faster. This saves not only time but also costs. Minimise your failure costs with the HYDAC p0-guard.
Functional safety
Hydropower plants are climate-friendly, cost-effective and – above all – reliable. Many years of dependable plant operation confirm this. With HYDAC you are always on the safe side: reliable components and monitoring systems, developed for your country’s specific requirements with many years of successful operation in real applications. Together we can take care of the functional safety of your hydropower technology.
