Fluid conditioning
Clean fluids are fundamental to reliable operation of a system. Many companies know this and place value on cleanly filled oil, fluid conditioning, and fluid analysis. But when is a fluid really “clean”? What are the requirements on the cleanliness of a fluid? Our experts will create a custom strategy for you to reduce your costs. Find out more!
HYDAC fluid conditioning—your system protection for hydraulic and lubrication
Challenge: system availability & component service lifeAchieve greater performance and safety of operation with the right strategy
Solid, fluid, gaseous, and even gel-like contamination in hydraulic and lubrication systems leads to shorter fluid and component service lives, system failures, and reduced system productivity.
This makes it all the more important to condition the fluid extensively while monitoring the oil condition.
Our solution: fluid conditioning 4.0Digitization of processes in maintenance calls for smart solutions
For a system to be fully efficient and safe, it needs a sophisticated fluid conditioning strategy and continuous online monitoring. Only a holistic approach can permanently improve the state of the used fluids, significantly increase machine availability, and decrease the operating costs (cost reductions of up to 30% are not uncommon).
HYDAC fluid units with smart sensors can create the required oil condition. Our portfolio focuses on sustainability and includes all the components and complete solutions needed to implement it—with the right product for every application.
Removal of solid particles
Firmly integrated into your system, offline units perform fine filtration and thus ensure continuously high oil cleanliness. As they provide optimal operating conditions, HYDAC units enable very cost-effective filtration—regardless of how your overall system is operated. Even in mobile use, whether it’s in service or for care and maintenance, our HYDAC solutions provide both offline filtration to systems and filtered filling and transfer of fluids. Thanks to tried-and-tested HYDAC sensors, your system can have optimal protection from the outset.

HYDAC service unit MobileFiltration Unit MFU 15
The MobileFiltration Unit MFU is used as a portable service unit for filling hydraulic systems, flushing small hydraulic systems, and for cleaning in bypass flow. Optionally with integrated monitoring of the solid particle contamination in accordance with ISO4406.
HYDAC MobileFiltration Unit MFU 30-100 service unit
The units in the MobileFiltration Unit MFU-30—100 series are mobile service units for flow rates from 30-100 l/min. Particulate solid contamination and free water are removed via the filter elements, and the optional measuring technology helps with the continuous fluid monitoring. Wireless communication and connection to cloud portals enable integration into modern I4.0 environments.
HYDAC service unit FiltrationUnit OFX
As a portable service unit, our HYDAC FiltrationUnit OFX enables filling and draining of hydraulic systems. The 45 bar operating pressure also means it can be used to fill and vent supply circuits of hydrostatic transmission drives and work hydraulics in a closed circuit.
Separation of fluids and gases
From water to gas—depending on requirements, our HYDAC solutions use cutting-edge methods for separation. Whether it’s the vacuum method, coalescence method, or superabsorber, our HYDAC solutions enable efficient separation of free and dissolved water, gases, and air. Used in conjunction with efficient offline filtration, they give your hydraulic system optimal protection. We develop solutions that meet the specifications of system manufacturers.
Our HYDAC solutions for dewatering and degassing your machine
HYDAC dewatering units
For separating free and dissolved water as well as gases: our FluidAqua Mobil series is highly economical thanks to the combination of the vacuum method and efficient offline filter element technology. Thanks to efficient separation, our unit ensures the lowest possible residual water content, gas content, and particulate contamination for your operating fluids.
HYDAC Coalescer
HYDAC coalescers are used to separate free water. They work very efficiently and are also low-maintenance. They are suitable for hydraulic oils and lubrication oils with densities below 950 kg/m3.
The coalescers are also the ideal solution in situations where water continuously enters the system.
HYDAC filter solutions with integrated water separation (superabsorbents)
The high-quality Aquamicron filter elements are suitable for the efficient separation of solid contamination and also have the ability to absorb residual water from the fluid. This allows you to efficiently protect your system and fluids from contamination-related system failures and high operating costs with just one element.
Separation of oil degradation products
Because modern fluids have different basic oil properties, gel-like or even varnish-like deposits have become more common. In machines with high fluid loads in particular, this means an increase in new kinds of deposits, significantly changing how the oil deteriorates. A factor that dramatically reduces both the component service life and productivity.
To counter this, HYDAC can support you with efficient systems for separating oil degradation products. This means you can fully exploit your system’s potential and save valuable resources!
For your hydraulic or lubricating oil applications: our HYDAC product range for separating varnish
HYDAC VarnishElimination Unit VEU-F
For the removal of solid or gel-like oil degradation products: the service-friendly VarnishElimination Units VEU are used to condition mineral oils. They are particularly effective at removing oil degradation products from mineral oils.
HYDAC VarnishElimination Unit VEU-I
The easy-to-service ion exchange units of the VEU-I series are used for the preparation of phosphate-ester-based (HFD-R) flame-resistant hydraulic and lubrication fluids.
They effectively remove the acidic decomposition products arising from hydrolysis and/or oxidation of the fluid, and metal ions. Depending on the resin elements used, water contained in the HFD-R oil can be separated.
