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.

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 fulfil 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 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”.

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.
