New pipe bridges, new base frame, and even higher quality design: The partners of KSI Filtertechnik and especially the service staff of the numerous specialist dealers can be pleased about the upgrade of the heatless regenerated adsorption dryer ATK to ECOTROC ATKN. The relaunch brings some additional practical improvements, which will be clearly noticeable in terms of both installation and maintenance. In the middle of the year, KSI switches to only supplies the further developed ECOTROC ATKN.

The new pipe bridges, among other things, make maintenance easier and thus save time. They considerably simplify the filling and emptying of the desiccant containers and also facilitate the replacement of maintenance parts. 

Important: The dimensions change only slightly due to the product relaunch. The performance levels and prices (!) remain unchanged.

KSI establishes new “KSI LLC” in Kosovo

Looking forward to a successful cooperation: Holger Krebs (l.) and Bekim Gashi.

The KSI company from Willich, Germany, adds a new milestone to its more than two decades lasting history: Managing director Holger Krebs and his businesspartner Bekim Gashi establish the new KSI LLC in Pristina, the capital of Kosovo. In the future, Pristina is the basis for bringing KSI products to the Balkan states such as Kosovo, Serbia, Albania,  Macedonia and Bosnia-Herzegovina.

“We are very happy and proud to take this new, important step”, explains managing director Holger Krebs. “It was really much work to be done for us. Many meetings in Pristina and in Willich, and many arrangements… But suddenly, everything went very fast”, says Krebs.

The new subsidiary KSI LLC in Kosovo is now the next mainstay of the KSI Filtertechnik. Before that, the owner-managed family company from Willich has already established subsidiaries in the Czech Republic, in England and the Netherlands.

KSI assumes sponsorship for horse Pinot Grigio on Gut Aiderbichl

Pinot Grigio

KSI Filtertechnik is now the sponsor of the 19-year-old Hannoverian stallion Pinot Grigio, who is based at Gut Aiderbichl near Salzburg. KSI Managing Director Holger Krebs and his family signed for this during their visit at Gut Aiderbichl, which gave name to several well-known animal courts of grace in German-speaking countries.

“Our entire family is really impressed by the great work that is done there for the animals! This really goes straight to the heart, how they take care of the many animals of different breeds and species”, describes Holger Krebs his impressions.

The history of Pinot Grigio exemplifies so many animals that have found a new home on Gut Aiderbichl. When the Hannoverian was diagnosed with a heart defect, the 1.96 m tall stallion was suddenly no longer suitable for his dressage stall. So his rider, at the same time veterinarian, took care of the accommodation on Gut Aiderbichl. And there the Krebs family became aware of the black horse.

Lukas Krebs completes the family business

The KSI Filtertechnik now is a completed family business: Since the youngest family member joined the company, the whole Krebs family is working at KSI. Father Holger, mother Heike and both sons Mirko and Lukas.

Holger Krebs, head of both the familiy and the company, defines family business a little bit different than others. Usually, in family companies the lead is handed over from generation to generation. But at KSI the complete family is already working together. Heike Krebs works at the accounting, and both sons get to know the company in parallel to the course of their studies. „My sons have been free to choose and plan their career“, describes Holger Krebs. „Now I am very lucky and proud that both decided to study industrial engineering, so they get a very deep insight of the KSI’s daily business already at university.“

Proud father with his sons: Holger Krebs in between Mirko (l.) and Lukas.

When not being at the library or enjoying some leisure time, Lukas and Mirko stay at the company site in Willich. They create and update price lists, brochures, product data sheets, all in English and German language. „By working on these printed brochures we get to know each department of KSI. The construction, the assembly, and even the sales department – that does not become stale at all“, explains Lukas Krebs.

At the moment Mirko, the older brother, is doing a practical semester. Soon he will finish his studies at the well-known technical university in Aachen; the topic for his bachelor thesis: compressed air technology. Afterwards he wants to get his master’s degree.

Lukas, the younger one, is standing at the very beginning of his university career. He studies industrial engineering at the technical college of Düsseldorf.
