79 years ago, in 1946, HAUSER received its first licence decree – its official trade licence. At that time, engineer Rudolf Hauser registered the sole proprietorship under the name ‘Ing. Rudolf Hauser, Kühlanlagenbau’ (Refrigeration System Construction).
Mr Rudolf Hauser had three business licences with the following wording:
- Water pipe installation limited to the construction, maintenance and repair of refrigeration systems
- Trade in refrigeration machines and refrigeration systems, including accessories and spare parts
- Factory production of refrigeration systems, refrigeration units, air conditioning systems and commercial equipment
At the proud age of 79, we can look back on a long history of success – and yet in 2025 we are just as innovative and dynamic as we were when we started out under our founder Rudolf Hauser. A lot has happened since then: What once began as a small service company in Linz is now an internationally active, future-oriented and family-oriented company. From exciting projects and inspiring employee events to continuous growth across national borders – HAUSER has always stood for progress and further development.
Today, we are taking our birthday as an opportunity to look back on some of the highlights from the past year:

- Winner of the State Prize for Best Training Companies – in the category ‘Training initiatives in companies with up to 50 apprentices’
- Open day in Kaplice, Czech Republic – a successful event with a family programme and a surprise performance by a live band.
- Exhibition of Erwin Hauser's art collection at the Lentos Art Museum
- Linz Danube Marathon 2025 – with top results for our HAUSER sports family!
- VITHEA achieves top results in external counter test – and stands out from eight other producers with an overall score of 92 out of a possible 100 points.
What a look back on an eventful and successful year! And the next one is guaranteed to be no less special – because then we will be celebrating our 80th anniversary. What the future holds remains to be seen – but we look to it with confidence, armed with courage, solidarity and a spirit of innovation.
