HYDAC (company)

HYDAC (company) is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand HYDAC (company) rather than just read about it. In short: HYDAC is a German company group that specializes in the production and distribution of components and systems as well as services related to hydraulics and fluidics. Hydac is constituted of 15 legal entities, all of which are GmbHs, companies with limited liability.

Key takeaways

HYDAC (company) belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect HYDAC (company) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of HYDAC (company) from memory before moving on to harder problems.

Reference excerpt

HYDAC is a German company group that specializes in the production and distribution of components and systems as well as services related to hydraulics and fluidics. Hydac is constituted of 15 legal entities, all of which are GmbHs, companies with limited liability. CEOs for these companies are Alexander Dieter, Wolfgang Haering and Hartmut Herzog. Subsidiaries exist in more than 10 countries. In 2011, the company had approximately 5,500 employees.

History HYDAC was founded in 1963 by Werner Dieter and Ottmar Schön, when an exclusive license for central Europe for a hydraulic accumulator was taken out. The name HYDAC is an abbreviation for "hydraulic accumulator".

Company structuring In 2015, HYDAC had 9,000 employees, 50 subsidiaries, and 500 distribution and service partners. The company group is headquartered in Sulzbach (Saarland). More than 3000 employees are employed in Sulzbach. In 2014, the subsidiary with the highest revenue was HYDAC Technology GmbH with revenues of €445.6 million and 384 employees. In the same year, HYDAC International GmbH and its 466 employees, which is presently providing distribution services to the other subsidiaries of the group, had revenues of €75.9 million. The groups subsidiaries are:

HYDAC Technology GmbH in Sulzbach / Saar HYDAC Filtertechnik GmbH in Sulzbach / Saar HYDAC Fluidtechnik GmbH in Sulzbach / Saar HYDAC International GmbH in Sulzbach / Saar HYDAC Verwaltung GmbH in Sulzbach / Saar HYDAC Electronic GmbH in Gersweiler / Saar HYDAC Accessories GmbH in Sulzbach / Saar HYDAC Process Technology GmbH in Neunkirchen / Saar HYDAC System GmbH in Sulzbach / Saar HYDAC Service GmbH in Sulzbach / Saar HYDAC PTK Produktionstechnik GmbH in Sulzbach / Saar HYDAC Cooling GmbH in Sulzbach / Saar HYDAC Filter Systems GmbH in Sulzbach / Saar HYDAC Grundstücksverwaltung GmbH in Sulzbach / Saar HYDAC FluidCareCenter GmbH in Sulzbach / Saar HYDAC Drive Center GmbH in Langenau HYDAC Speichertechnik GmbH in Sulzbach / Saar HYDROSAAR GmbH in Sulzbach / Saar Kraeft GmbH Systemtechnik in Bremerhaven NORDHYDRAULIC in Kramfors, Sweden QHP in Chester, England Hydac Engineering AG in Steinhausen, Switzerland BIERI in Liebefeld, Switzerland HYCOM in Apeldoorn, Netherlands

Worked examples

Example 1 — a first encounter with HYDAC (company)

Start with the simplest possible case. Write down what HYDAC (company) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to HYDAC (company) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about HYDAC (company) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of HYDAC (company)

In research: HYDAC (company) appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses HYDAC (company) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: HYDAC (company) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Companies based in Saarland, German companies established in 1963, Hydraulic accumulators, so understanding it makes those chapters shorter.
In everyday life: Look for HYDAC (company) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
