HYDAC fluid-water cooling systems
Fluid-water cooling systems are used in water glycol or mineral oil circuits. They enable energy-efficient use of existing factory building infrastructure to cool machines and systems. If cooling water is available, this cooling system is the solution of choice. This is because it combines the possibility of cooling beneath the ambient temperature with very low heat dissipation to the direct surroundings. HYDAC supplies various optional temperature control technologies and enables cooling capacities of up to 250 kW in various sizes.
HYDAC RFCS cooling unit
The active cooling systems enable high-precision cooling (± 0.1K) of machines and systems even below the ambient temperature, regardless of the available factory building infrastructure. HYDAC supplies these devices as built-in units or add-on units in various sizes for cooling capacities of up to 200 kW. The energy-efficient, patented mixer principle combined with a seal-less immersion pump round off this system, making it an all-round solution for machine tools.
HYDAC cold plates
Cold plates are used wherever electronic components have to operate at a high performance level and have to be cooled directly. The components that are to be cooled are mounted onto the cold plates directly, and a cooling fluid circulates through the plate and effectively channels away the dissipated heat. The cooling fluid itself can be supplied from and returned to the various HYDAC cooling systems. HYDAC cold plates feature a custom design, first-class quality, and dimensions of up to 1,600 mm x 750 mm.
Functional safety & occupational safety
As a result of current statutory regulations at a European and national level, such as the Machinery Directive 2006/42/EC, machine operators are having to focus on functional occupational health and safety and more protection at production workstations in factories. These regulations require manufacturers to keep creating new, documented safety solutions. Our HYDAC experts can support you and your colleagues with custom services, such as consultation during the project planning phase and Sistema calculations for integrating designed subsystems into your safety strategy, so that you can meet all the requirements imposed on you.
Functional safety & occupational safety for machine tools: our product solutions
HYDAC sensors for safety circuits & safety functions
HYDAC provides pressure transmitters and linear position transmitters for applications in functionally safe plants and systems up to SIL 2 (IEC 61508) or PL d (ISO13849). They have two channels and/or are equipped with self-diagnosis functions and are therefore suitable for use in safety-critical applications.
HYDAC actuators with electronic switch position monitoring & proportional technology
Using valves with switch position monitoring is another way for machine manufacturers to fulfill functional safety requirements (ISO 13849). Safety-related requirements can also be met with the correct use of proportional valves. As a long-standing manufacturer of valve technology, we supply an extensive range of suitable products for this purpose.
Energy efficiency & cost effectiveness
For a long time now, the topics of resource conservation and CO2 reduction have not only been about the environment, but also about the financial aspect. High CO2 emissions go hand in hand with high costs. This is all the more reason for machine builders to place importance on the development of energy-efficient machine tools. After all, end users and consumers want goods to be produced in an economical way that conserves resources. We support you with this with custom services and products.

HYDAC propane cooler RFCS-Smart Line
The new RFCS S0 cooler from the SMART Line enables propane to be used as a coolant. Compared with the coolants already in use, propane has a very low GWP value of 3. Despite using this environmentally-friendly coolant, the cooling unit uses tried-and-tested technology, has a compact size, and enables a cooling capacity of up to 1.5 kW.
HYDAC KineSys variable-speed drive solution
If a broad range of flow rates is needed in hydraulics at constant pressure ratios, variable-speed drives make it possible to always provide the precise capacity that is required by the system. HYDAC provides two systems for this: the inexpensive standardized CO3 unit and the customizable DVA unit that is available in various capacity classes up to 22 kW.
HYDAC Stat-X® filter element technology
Over the past few years, the trend towards ash-free hydraulic fluids, more compact systems, and finer filtration has led to increasing problems with electrostatic charging and discharging in hydraulic and lubrication oil systems, leading to much faster oil degradation. With the pioneering Stat-X® element technology, HYDAC makes it possible to demonstrably reduce this electrostatic charging and discharging in the filter while providing excellent ultrafine filtration.
Automation, digitalization & industry 4.0

HYDAC smart start-stop power unit CO1S
If hydraulic units are to work efficiently, they need to be operated within the prescribed operating parameters. Conventional power units have limited options when it comes to condition monitoring. The smart CO1S start-stop unit from HYDAC enables constant communication between the unit and the machine thanks to the integration of IO-Link technology. This means that pressures, runtimes, temperatures, and the remaining filter service life can be monitored. This data forms the basis of high machine availability, needs-based preventative maintenance, and new payment models such as “pay per use.”

HYDAC coolant management FCU 5000
Automate your machine's coolant management. The Fluid Control Unit 5000 measures the precise concentration, pH value, electrical conductivity, and temperature of your coolant. Fully automatic topping up ensures that concentration levels remain stable. The tank level is also kept at the target level thanks to intelligent refilling. Dashboards, active recommendations for action, e-mail alerts for personnel if problems occur, and data embedded in the cloud round off our all-inclusive package in the spirit of Industry 4.0. Thanks to our fluid controllers, up to 10 measuring points can be connected.
Automatic back-flushing filter AutoFilt®
Mechanical machining processes contaminate the coolants used. This means that filters are required for production to run smoothly. And this is exactly where our automatic back-flushing filters come into use – they work according to the working principle of a surface filter and automatically clean themselves with automatic back-flushing. The result: your machine tools can continue their work uninterrupted while our filters remove the damaging particles – allowing work to continue without disruptions or downtimes. At the same time, you also use less coolant thanks to careful filtration.
