Operating shareholdings

The SENN Gruppe is the family brand of Senn Beteiligungs GmbH and is operationally active as a one-stop store in the production and distribution of industrial supplies.

The group comprises 7 operationally active companies as of the beginning of 2023:

The individual companies are active in different product areas, which are listed in the illustration below. Thus, we are able to supply a wide range of products from a single source.

In line with our motto: "With united forces."

Our history

The SENN Gruppe was founded in 2001 with the first company KS Kneissl & Senn Technologie GmbH. Initially located in Kufstein, Austria, the company is now based in Erl, Austria. KS is the largest company in the SENN Gruppe, both in terms of employees and turnover, and is active as a producer and distributor in several product areas. Originally based in Kufstein in the old Kneissl ski factory, the company has been at the Erl site since 2013.

RBS Kompensator GmbH has also been part of the SENN Gruppe since 2009. The level of participation here is 75%. As the name suggests, RBS is involved in the production of (fabric) expansion joints within the group, and since 2019 also in the (contract) production of metal parts and flanges.

In 2013, the move to Erl with both companies then took place and, at the same time, Senn Immobilien GmbH was founded for the newly purchased real estate and properties. At the same time, Senn Beteiligungs GmbH was founded and has since acted as the parent company for the individual group companies.

In 2017 and 2018, the acquisitions of the companies Gasser GmbH and Ceratec GmbH followed, as the previous owners had no successors and the products perfectly complemented the product portfolio of the SENN Gruppe. Since 2022, both companies have also relocated with the site to Erl.

In 2018, the first extension of Hall A in Erl then took place. This allowed us to increase the high-bay capacity by another 1800m2.

During the pandemic, further partial business areas of the companies Wystrach Gießereitechnik and Active Feuerfest were taken over and integrated into the business of Ceratec GmbH and Gasser GmbH.

Senn Kraftwerke GmbH was founded at the end of 2021 in the course of the purchase of the Trockenbach Erl power plant. Since then, all energy generating activities of the SENN Gruppe have been bundled in it. In addition to hydropower, we focus primarily on photovoltaics. In total, between 1.5 and 2 million KWh of sustainable electricity can be produced.

Sinteca HandelsgmbH was founded in 1991 in Vienna under the company name Aladin and has since been engaged in the distribution of plain bearings, Niro plant parts, sintered filters. Since the beginning of 2022 Sinteca belongs to the SENN Gruppe. With 2023 also the distribution of technical maintenance products and mechanical seals of the company Chesterton belongs to the product portfolio. In contrast to the other companies, Sinteca operates in Klosterneuburg, Lower Austria. Sinteca is a 90% subsidiary of the SENN Gruppe.

2023 saw the opening of the new production and storage hall HE. On a total area of 3500 m2 additional production areas for the manufacturing of expansion joints as well as the new product area of metal parts for own use and in contract manufacturing will be created here. In addition, an expansion of the high rack capacity will take place.

Since October 2023 Senn Logistik GmbH strengthens the Group in internal and external logistics matters. In addition to full truck loads and forwarded goods, we also offer LTL and sprinter services for third-party customers and our own needs.

At the end of 2023, the vermiculite manufacturer K. Hoffmann GmbH in Plettenberg was added to our group. This enables us to significantly expand our expertise in the field of vermiculite (pressed parts, CNC-milled moulded parts and panels).

Principles of the group

Consistent reinvestment of profits in our own machinery (milling, sawing, plotting, punching, water jetting, welding, laser cutting etc.), know-how and above all our employees make us an important system supplier of industrial supplies such as lubricants, seals, refractory products, conveyor chains, plain bearings, expansion joints and foundry supplies in Central Europe.

Together with our team we try to live the idea of the "One Stop Shop" and make sometimes impossible things possible according to our motto: "Viribus Unitis - with united forces".

Our actions are subject to a business, social and ecological very high sustainable standard. Compliance with legal requirements and continuous improvement of operational performance are the basis of our actions. The family business guarantees the successive development and long-term expansion of the company by ensuring balanced relationships between customers and products and employees in harmony with our environment.

In this sense, profits are left in the company and reinvested in the long term. The focus is on our customers, whose needs represent our highest challenge. Very well-trained and motivated employees help - dynamically and future-oriented - to achieve our long-term goals.
