From setup and installation, through to pipework and system flushing, and finally to pressure testing and actual commissioning, an experienced team of project supervisors, electronic engineers, electricians, hydraulic engineers, fitters and welders are available for assignments around the globe.


We undertake repairs for the entire HYDAC product range as well as other makes of equipment. Depending on your requirements, we can carry out individually commissioned repairs with prior consideration to costs and develop repair packages to include spare and reserve parts.


Inspections and maintenance of system plants. Regular checking of the operating system prevents expensive downtime.
The HYDAC Service Centre monitors, oil condition, oil level, filter condition, accumulator pressures and valve settings. Switching shocks and vibrations are recorded using the latest measurement technology; parameters are analyzed and logged. Using this information as a basis, inspection intervals are adapted to the requirements.

We can also check safety components, such as steam testing units.

Fluid Handling

Fresh oil filling, tank cleaning or complete oil change.

Professional handling when transporting fluids over distances of up to 120 m and volumes of up to 200 m³, including the flushing of pipes.
Preliminary monitoring of the machine/system for cleanliness, safety equipment required and obvious leakage sources. Blanking off pipes / user unit and filling the machine/system tank from a tanker or other containers via a filtration unit.. Machine/system flushing in the main circuit until the required cleanliness class is achieved.

Continuous measurement of the cleanliness class in the flow as well as sampling of the oil to provide a reference sample for future comparative measurements. Connection of pipes/user unit and final leakage check. Complete documentation of the work and cleanliness class including completion of a Service Log which remains attached to the machine.

Fluid Management

Package concept for all aspects of fluid and components.

By entering into a full-service or maintenance contract, you will receive a coordinated package of services – from the supply of media and components, through engineering to hydraulics and facility services that are geared towards the following objectives: savings in maintenance costs, savings in investments and labour cost optimization. Fluid engineering means an increase in process reliability, taking proven technologies into account.

Technical services

With regard to specifications, spare parts, repair, maintenance and optimisation of oils, water, lubrication, cooling lubricants and air. We analyze your production and servicing workflow from the technical and commercial point of view of fluid power technology and make a critical analysis of existing concepts and cost accounting. In this way, we move from the individual examination of the medium or component to a holistic approach.

From the idea to the implementation. An idea alone is not a guarantee for success. The HYDAC Service Centre ‘accompanies’ you in every step of the implementation. Fluid engineering is a dynamic process that must be continuously monitored for its suitability. Here, you can rely on the HYDAC Service Centre with a team made up of fluid managers, team leaders and service staff.

Optimisation and Planning

Increasing operational availability and  productivity.

Technical progress waits for no-one. In many applications, machines purchased today can no longer produce the quality required tomorrow. Instead of buying new, an excellent alternative, both technically and in terms of cost, is often to convert and modernize the components and systems used.

By examining the hydraulic system in partnership, we can find potential for optimisation together. In other words, we can generate a reduction in costs and an increase in productivity and operational availability, with results to match.

Condition Monitoring

CM-Expert is a high-performance monitoring / archival and control system for Condition Monitoring which can be installed on any standard PC.
Its decentralized configuration makes the system extremely reliable and flexible for use in production systems. As regards connecting sensors, operating and signal components, control tasks and data exchange with other
systems, by using the data acquisition unit (MDE), no limits are placed on the system. All common physical parameters can be recorded by the MDE and processed by the CM-Expert: temperature, pressure, differential pressure, viscosity, water content, particles, flow rate, etc.

Areas of application:

  • Steel works
  • Wind turbines
  • Plastics machinery
  • Paper machines
  • Machine tools
  • Hydraulic presses
  • Test stands and all other production processes requiring monitoring

Online Monitoring of production systems. Directly on-site or via remote access! Our ‘remote’ version of the CM-Expert is perfectly applicable to wind energy, offshore applications and mobile hydraulics. It informs the operator in real time about the condition of their system and initiates service exactly when it is needed. Unnecessary (and thus expensive) maintenance has now become obsolete!

Your advantages:

  • Continual monitoring and logging of the ambient conditions and the automated messages from the production media when defined service limits are reached (e.g. filter change)
  • Immediate warning when defined limits are exceeded
  • Avoids unnecessary maintenance on systems where access is difficult
  • Prevention of major breakdowns by means of early detection
  • Optimisation of the maintenance intervals
  • Reduction of the maintenance and repair costs
  • Prevention of downtime
  • Prevention of consequential damage.


Optimise the quality of your test equipment by using the calibration service at HYDAC Service Centre.

In order to guarantee that all the test equipment measure accurately under controlled parameters, they must be calibrated regularly with the calibration process traceable to national measurement standards, and the results documented and certified.

We calibrate the following equipment: CS and FCU (1000 and 2000 series).

Fluid Analytics

The condition of the fluid is crucial for optimum machine performance today. This means that the fluids must be monitored and tested.

The required tests are:

  • Oil analysis
  • Cleanliness determination and analysis, internal company standards for the automotive and supplier industryParticle distribution measurement acc. ISO 4406 and SAE AS: 4056
  • Determination of water content according to the Karl Fischer method
  • Microscopic analysis
  • Gravimetric analysis
  • Granulometric analysis
  • Density
  • Viscosity
  • TAN (Total Acid Number)
  • Coolant / lubricant analysis and water analysis (pH-value, conductivity, bacteria, chlorite, nitrate, nitrite, ° dH)
  • REM/EDX analyses
  • Process chain analysis

Process Optimisation

HYDAC can bring its many years of experience in the fluid industry to your production, performing on-site process chain analyses.
Process chain analyses define the state of technical cleanliness in the production process. We locate your potential for optimisation and develop measures to further improve component cleanliness values.

Technical Cleanliness

From a clean component to a technically clean system.

Technical cleanliness is becoming increasingly important in many sectors of industry, the automotive industry, mobile hydraulics and production systems. Phrases such as ‘reduction and avoidance of start-up breakdowns’ and the difficulty of ever-increasing warranty periods are driving the demands for component cleanliness.

Suppliers and producers of complete systems are required to meet more demanding technical cleanliness standards for their products and systems.

We perform lab analyses as well as internal company standards, and perform site process chain analyses.

Rental Service

Hire the equipment as you need it. Instead of tying up capital unnecessarily.

When equipment is only required for short periods, there is understandable opposition to making any costly investment.
Hiring the equipment is an economical and flexible alternative.

Whenever you need a piece of equipment, a measuring unit or a mobile filtration system – it’s there ready for you! All units are maintained and checked regularly and are therefore always ready for operation.

Our specialists will be pleased to advise you in advance on selecting the best unit for your application. We will ensure that the hire equipment will be available on schedule, and therefore that your project runs smoothly.
