Part of a strong technical heritage
Stelzer was previously part of the UTG Mixing Group, formed in 2015 through the merger of Uutechnic Oy and the Vaahto Group (formerly Japrotec / Jamix), the parent company of Stelzer Rührtechnik International GmbH. Through this collaboration, modern resources such as a physical test laboratory and advanced CFD simulation capabilities were developed.
Certified quality in every project
To ensure optimal and reproducible results, Stelzer operates according to documented quality and safety procedures based on DIN EN ISO 9001:2015. This means that customers choosing Stelzer solutions benefit from project management and engineering that meet high international standards.
Stelzer’s areas of expertise
Many of Stelzer’s agitators are used in the pharmaceutical, food, and advanced chemical industries, as well as in biogas and other markets. The product portfolio is extensive and includes direct-driven, geared, and magnetically coupled agitators.
Stelzer is also at the forefront of gas-in-liquid processes, with impellers designed to both disperse and retain large volumes of gas in liquids, enabling high kLa values.
In addition, Stelzer has a strong presence in the dairy industry, where agitators for yoghurt and other high-viscosity products are widely used.
