Today, hydro-electric power stations make an important and sustainable contribution to the world‘s energy supply. HYDAC is determined to play its part in enabling people to gain maximum benefit from hydropower. In opening flood gates and intake gates. And in efficiently regulating and protecting turbines and generators. HYDAC proves its expertise with hydraulic and filtration solutions in all sectors.

HYDAC has decades of experience in oil hydraulics and process water treatment. With individual components constantly being ­added to the product range, such as filters, accumulators, valves, pumps, coolers and sensors, HYDAC has built up an extensive and complete product portfolio over the years that leaves nothing to be desired when it comes to designing systems for the hydropower industry. In addition to supplying individual components, HYDAC also provides complete systems for almost all hydropower applications. These are comprehensive systems which are specially tailored to suit the customer‘s needs. HYDAC was founded in 1963 as a company for hydraulic accessories and is today an international, family-run company group with over 11‘500 employees, 45 subsidiaries and more than 500 sales and service partners worldwide. Our motto is: global yet local. HYDAC components and systems can be found in all sectors of industrial and ­mobile hydraulics.

Comprehensive product portfolio
In the hydropower industry, HYDAC is represented in the following applications for both large and small hydropower stations:

• Hydraulic steel structures and trash rack cleaners: hydraulic units and cylinders for gate, sluices, weirs and trash rack cleaners

• Shut-off devices: hydraulic systems for ball valves, shut-off valves and needle valves, piston and bladder accumulator stations for ­s­toring closing power and water-powered servo motors with corresponding protective filters

• Turbines: bearing lubrication systems, hydraulic turbine controllers, piston and bladder accumulator stations for the emergency ­shut-down function

• Process and cooling water treatment: for the filtration of seal water, cooling water and extinguishing water, the required components – e.g. the automatic back-flushing filter RF3 or ATF – are mounted on a compact frame (skid)

Generators: lifting and brake cylinders, oil lubrication cooling ­systems and cooling water systems, high-pressure discharge systems (HP systems), brake lifting systems, oil mist separators.

Worldwide services
HYDAC also supplies products for Condition Monitoring, such as sensors for monitoring water content (Aqua Sensor), metallic con­tamination (MCS Sensor) and the automatic monitoring oil cleanliness (CS Sensor) along with service instruments for maintenance such as dewatering units (FAM), offline filtration units (OLF), nitrogen charging units for accumulators (N2 server) and mobile units for measurement and data acquisition (HMG). The HYDAC portfolio is rounded off with extensive fluid engineering services which help to optimise your key components and fluid power systems. We are very happy to support you in areas such as energy efficiency, process and system reliability, conservation of resources and system availability.
