promix – Plant engineering since 1992: concrete tank stations & bulk material vending machines from our own production
To date, promix has planned, built and commissioned more than 50 concrete tank stations and bulk material vending machines in the DACH region. Behind every system are our own design, our own production, and a service team that supports operations over the long term.
Family-run for over 30 years
promix is a brand of RK-Prozesstechnik GmbH & Co. KG, headquartered in Lauchringen. The family-run company has been an expert since 1992 in developing innovative plant and control technology for building materials retailers, construction companies and the construction industry.
Since 2020, we have been producing modular concrete tank stations and self-service payment terminals, and since 2025 bulk material vending machines for Germany, Switzerland, Austria, Poland and France.
A key advantage is our high level of vertical integration: all our fully automated self-service systems are developed and manufactured entirely in-house. This ensures maximum quality, flexibility and systems perfectly tailored to customer requirements.
With around 30 employees and service bases in Recklinghausen and Cottbus, we have a nationwide presence and, as part of our service, also support you with the planning, financing and maintenance of the systems we offer – everything from a single source.
