Price list update valid from 1st of May – but no increases!

When we first published it a good year ago, we promised, and we keep our word: Our update to our popular PRODUCT AND PRICE LIST comes without price increases! The new version comes into force on 1st of May 2020 and replaces all previous versions. The 120-page reference book is much more than just a familiar reference…

It has already been a whole year since KSI Filter Technology presented its latest product developments to the world public for the first time at the ComVac in Hanover: the KSI ECOCLEAN APF filter series, the ECOTROC AT-HP high-pressure adsorption dryers and the KSI ECOCONTROL online plant monitoring system. All of these are important and successful innovations in KSI’s extensive product range, but of course by no means all of them. A further developed heat-regenerated adsorption dryer ATW-S, new cartridge filters for the APF series, high-pressure adsorption dryers now up to 500 bar, technical innovations for the medical adsorption dryers ATM, … – the list of innovations could easily be extended.

This comprehensive update is only available in digital form and via download. The corresponding link is available from our sales department on request ( Tel. +49 2154 89108-0).

Joyful Christmas atmosphere at KSI’s winter festivities

­Finally, the KSI’s combination of a family winter market and a Christmas party in the evening, developed as desired by the organising committee: shining eyes, all colleagues in a joyful and festive mood, a nice festivity with the families, the closest friends and business partners of the companies from the Siemensring 54-56. KSI’s Managing Director Holger Krebs found the right words to describe it precisely: “It was a great festivity. Awesome.”

The great winner of the Christmas lottery was the “Löwenkinder” (lion kids) initiative which helps children suffering from cancer. In the next few days, the KSI donates 1140 Euro to the initiative.

KSI rushes into the EURO quarterfinals

For sure, many of us have rubbed their eyes and smelled a brilliant marketing coup behind that. The Icelanders are really wearing nice, blue jerseys with the letters KSI on it … So to speak: Hammerson!

And in fact, the supposed move could not have been better. No other participant of the EURO is allowed to wear jerseys with advertisings on the pitch, so the Icelanders with the KSI lettering on the left chest are a now famous exception. And with their strength, their cleverness and their powerful way to play football, they beat the English team 2:1 and kicked them out of the tournament. They already made their way into the history books of European soccer, and now they are challenging the French.

“Now we all have another, second reason to press thumbs for the KSI,” manager Holger Krebs admits frankly and with a smile. “At least until they play against Le Mannschaft. From that point on it is enough to cross fingers only for our company.”

The KSI on the jerseys of Iceland is the Football Association “Knattspyrnusamband Islands”.

KSI supports “Le Mannschaft” at the Euro in France

With fingers crossed the KSI Filtertechnik supports the team of the world champion at the European football championship in France. The colleagues and friends of the KSI come together in the company’s forum to watch the matches of the German team and the matches of the competitors together.

These events are accompanied by some grilled food and chilled drinks and all kinds of sweets for children. “We only needed a video projector and a bit of decoration in black, red and gold, and we easily transformed our forum into a championship arena. So we can cheer at the Euro also among our colleagues”, commented Managing Director Holger Krebs.

Fingers crossed for "Le Mannschaft": colleagues and friends of the KSI come together in the forum to watch football together.
