- Deposits
- Fouling
- Corrosion
Diesel fuel filters
-
In order to meet the requirements for diesel fuels, it is not sufficient to treat diesel only immediately before use on the machine. The fuel must be filtered and dewatered at every station in the transport chain - from refinery production to the end user. Monitoring particulate contamination and water content is essential to comply with high quality requirements.
Innovative solution in solid design.
In addition to the on-board products for smaller diesel quantities on consumer devices, products for larger volume flows are also available. These are used during transport between different reservoirs, at petrol stations, and thus at the transition to the engine.

- While fluids are practically incompressible, this does not apply to gases. Hydraulic accumulators use these basic laws of physics to store hydraulic energy. Nitrogen is normally used as the compressible medium. The various types of hydraulic accumulator are categorised on the basis of the separation element that keeps the gas section separate from the fluid section in the pressure vessel. In the case of metal bellows accumulators, this is a metallic corrugated or diaphragm bellows.
Hydraulic dampers

Coaxial valves
- The compressed air with the spring produces a pre-charge force on the closing cone and this is pressed onto the valve seat. Hydraulic compressive force is exerted on the opposite side of the closing cone. If this is below the pre-set pre-load force, the valve is closed. If the hydraulic compressive force exceeds the pre-set pre-load force, then the closing cone is lifted away from the valve seat and operating fluid flows from pressure port P to tank port T. This has the effect of limiting the pressure at port P. The hydraulic energy used is converted to heat and the operating fluid is drained to tank.

Thermal Management
Air coolers
- Air cooling is a convenient method of dissipating heat loss from industrial and mobile systems.
The medium to be cooled – usually oil or a water-glycol mixture – flows through a heat exchanger. A fan draws in ambient air and feeds it through the cooling element. The difference in temperature causes a heat exchange to take place, whereby the cooler air absorbs the heat from the medium and releases it back into the atmosphere.
This allows the medium to be cooled down to a few degrees Celsius above ambient temperature.
At HYDAC you will find the right air cooling unit to suit your needs, from standard to large coolers for use in the energy sector or even custom-made coolers for mobile machinery.
Fluid cooling
- Liquid cooling is an effective and cost-effective method for cooling high output densities. Cooling below ambient temperature is also possible, depending on the temperature of the cold water used. Plate heat exchangers used either as an intermediate circuit or as a separating circuit help protect the system components from contamination and corrosion due to poor quality cold water.
HYDAC can offer you highly specialised solutions, such as fluid cold plates for cooling electrical components, as well as highly efficient screwed and brazed plate heat exchangers.
Cooling systems
- Greater safety through cool system solutions.
The heat produced by internal losses in the main spindle, drives, control cabinets, cooling lubricants and hydraulics can be dissipated very effectively by means of liquid cooling.
HYDAC has a wide range of cooling systems including air cooling, water cooling or compressor cooling to provide you with the optimum cooling solution that meets your requirements in terms of installation space, noise levels, control accuracy or maintenance requirements.

Electric cylinders
-
HYDAC electric cylinders (HEZ) are also known as electromechanical linear actuators. They consist of a nut-spindle drive that is driven by an electric motor. Electric cylinders only require electrical energy, which means they can be used very flexibly and decentrally.
They do not contain any hydraulic oils, only lubricants. Our electric cylinders are available with adjustment forces from 1 kN to 500 kN and stroke lengths of up to 5 metres. There are various designs and series that differ in terms of the connection between the motor and the threaded spindle as well as the area of application. Our product range also covers all areas of application. From simple adjustment functions with occasional movement to highly dynamic work functions in continuous operation. Electric cylinders are maintenance-free for their entire life.
Variable-speed drive solutions
- Variable-speed drive solutions control the drive motor so that kinetic energy is provided according to requirements.
The drive controller with its three-phase motor is the core of variable-speed drive solutions. This controller either powers a hydraulic system or the spindle drive of an electromechanical cylinder.
This technology makes extensive customisation of traditional hydraulic systems possible and, through this, achieve efficiency, such as: Reduced power and cooling requirements, lower tank and oil volumes, less material and lower weight.
Be it electromechanical cylinders or hydraulic systems: Variable-speed drives make it possible to network drive systems and make control tasks, commissioning and troubleshooting significantly easier. 
Drive controller
- Our drive controllers in the HFI (HYDAC Frequency Inverter) series control the speed or torque of three-phase motors.
We use our drive controllers to implement drive solutions for hydraulic and electromechanical systems. Our drive solutions include simple component sets as well as complete drive system solutions. Be it electromechanical cylinders or hydraulic systems: Our drive controllers are the missing link. They make it possible to network drive systems, reduce the number of components and the space required, minimise complexity and create efficiency.
Our drive controllers differ in terms of how they are mounted and how they are used.
Drive kits - component sets
- The DVA kit and HFI-MM kit are drive component sets that make it easy to switch to speed-controlled hydraulic pumps.
The HFI-MM kit includes an asynchronous motor with a modular drive controller. It provides a simple interface for operating a hydraulic pump at a variable speed. The motor and drive controller are already in alignment, both mechanically and in terms of parametrisation. The user is responsible for the layout of the operating points and the hydraulic pump connection.
The DVA kit also includes the hydraulic pump connection. We are responsible for making sure the right decision is made when combining motor output, motor type and hydraulic pump, documentation and functional testing. This ensures that the necessary hydraulic operating points are reliably achieved.

- Our nitrogen charging unit programme (N2 Server) encompasses mobile – portable and wheeled – and also stationary device types. They are used for the loading of accumulators, for supplementing the gas charging pressure and/or for the charging accumulator stations.
Actuators
- Hydraulic actuators combine the advantages of electricity and hydraulics. Consisting of a hydraulic power unit, work cylinder and position control, they provide precise positioning at high adjustment speeds and actuating forces.
Gas extraction
- Our Gas Separation Units GSU are special air separation systems that generate nitrogen from a compressed air supply, achieving N2 concentrations of up to 99.5%.
Electromobility
- In order not to pollute the environment with exhaust fumes, combustion engines are not used. Instead, an electro-hydraulic drive unit is used, which is connected to the local power supply.
High pressure hydraulics components
- BIERI high pressure hydraulics components include pumps as axial or radial units and valves of all types, suitable for pressures of up to 1000 bar and displacement volumes of up to 62.7 cm3/rev. or flow rates up to 32 l/min, and the corresponding accessories.
Pumps
- The BIERI line of pumps consists of axial piston pumps, radial piston pumps, pump combinations (combination of high-pressure radial piston pumps with low-pressure gear pump or radial piston design), multi-outlet radial piston pumps and ATEX-certified radial piston pumps. BIERI pumps are suitable for a wide range of pressures and delivery rates.
Valves
- The Bieri valve range includes linear-position, pressure, flow and check valves, suitable for pressures of up to 1000 bar and flow rates of up to 63 l/min, and the corresponding accessories.
