XERVON Oberflächentechnik smartens up Air Liquide’s tanks

Air Liquide’s acquisition of Airgas and its launch of its customer-oriented NEOS programme marked a further milestone in the company’s history. To make these changes more visual, the company also decided to introduce a new logo – the fifth since its foundation 115 years ago. A new logo, however, also means a large number of practical changes: besides having to have new business cards and letterheads etc., the large logos at Air Liquide business locations also had to be replaced – a case for XERVON Oberflächentechnik.

All services from just one company

This major project was carried out in 2017 and 2018 and involved a total of ten Air Liquide production plants across Germany and Austria. The majority of the stickers and signs at these sites had been attached to the large containers at the company’s filling and air separation facilities. The size and shape of these containers differed greatly – as did XERVON Oberflächentechnik’s tasks. In some cases, they “only” had to remove the old logos and replace them with the new design. In others, however, the company had to work on the actual surface of the tanks: cleaning them, removing any rust and applying new coats of paint.

Logos up to 76m² in size

Some of the logos that had to be installed were as large as 76m². It is not possible to attach such large structures in one piece. Which meant that XERVON Oberflächentechnik had to fasten the individual sections of the logo to the container to the exact millimetre – in some cases this involved up to 26 separate segments. For the most part, scaffolding and cherry pickers had to be used to ensure the work, carried out 58 metres above the ground, could be performed quickly and safely.

Relaunch in Oberhausen

The nitrogen tank in Oberhausen is a perfect example of the work that had to be performed during this project. This flat-bottom tank, which is part of Air Liquide’s air separation unit, is 26.5 metres high and has a diameter of 19 metres. Once the enclosed, storm-proof scaffolding had been erected around the tank, the surface was cleaned using high pressure water jets to prepare it for the coating work. The XERVON team then removed the old logos before recoating the surface of the tank and attaching the new logo.

Production continued throughout

  • XERVON Oberflächentechnik performed all of the tasks needed for the project itself, including the scaffolding. All of the site’s special features were noted and taken into account during the planning work. As XERVON’s team of operatives collaborated closely with the site managers throughout the project, Air Liquide’s operations were able to continue uninterrupted while the work was being completed. Project manager Joachim Kupetz from XERVON Oberflächentechnik’s branch in Bottrop commented: “Air Liquide was looking for a competent partner with a flexible workforce. At the same time, they wanted a company that fulfilled all the safety regulations.” Requirements, therefore, that reflect XERVON Oberflächentechnik’s own high expectations and which were – as always – met throughout this project as well.
