The  GHS Vakuumtechnik GmbH roots can be traced back as far as 1949.  

At that time Mr. Albert Henkaus established the company under the name of Albert Henkaus Vakuumtechnik in Frankfurt. Products such as the vacuum blade-type and vacuum tumbling dryer as well as the double cone dryer and vacuum drying chamber plants were part of the product portfolio already at that time. Old company records reflecting those days are still available and give evidence of the impressive range of products.
The company’s head office was later on relocated to Heusenstamm, in the District of Offenbach.

In the mid-60’s Albert Henkaus was taken over by Adalbert Klein. The take-over also meant that the company’s product portfolio was extended by plant engineering and vacuum drying plants.
In 1971 the company moved from Heusenstamm to Niederndorf near Freudenberg.  
As from 1982 a cooperation was established with Albert Klein, an apparatus engineering company (father of Adalbert Klein) in Niederfischbach which was then managed by the brother, Otto Klein. At the same time Klein Vakuumtechnik GmbH was founded and a department for vacuum technology set up at Albert Klein. Following the death of managing director, Otto Klein, in 1991, the business was managed by external managing directors from outside of this particular sector of industry.
The result was that in the middle of 1992 the cooperation between Albert Klein and Klein Vakuumtechnik GmbH was terminated. As a consequence there were two companies manufacturing under the name of “Klein” for some time,
offering identical products on the market. In 1996 only Klein Vakuumtechnik GmbH remained on the market exclusively,
offering products in the sector of vacuum drying technology. The year 2001 saw the company being completely restructured,
setting up GHS Vakuumtechnik GmbH, with a new corporate structure.  
By the way -  all members of the GHS Vakuumtechnik GmbH management started their vacuum-technical career at Adalbert Klein. Above all, Mr. Huber Happ should be mentioned, expert for Sales and Processes, who joined the company in 1969 as well as the current Managing Director, Mr. Günther Schramm, in his function as Project Planner and Production Controller, who joined the company in 1973.

Outlook:
In 2016 GHS Vakuumtechnik GmbH is handed over to former employees of a market-leading supplier of vacuum pumps and components located in the middle of Germany. This ascertains that the know-how in the section of vacuum drying technology, built up over many decades, will not be lost but be continued, including all products from the company history, supplemented by interesting vacuum processes and applications. In this context helium leak test systems, gas/helium recovery plants as well as mass-spectrometric applications should be mentioned in particular.  

The subject of leak test plants is extended by special customer-specific solutions, including alternative test gases and processes designed to be applied to a specific application. Selecting the measuring system determines decisively the investment costs of the overall plant and must therefore be designed meticulously together with the customer/user.  

Where the sector of vacuum drying technology is concerned, it continues to remain important that the best possible solution is only found together with the customer, and to implement this subsequently at a quality for which this mechanical engineering company is well-known.
