Who are we?
We are a second-generation family business based in Rheinbach. Founded by Werner Böhm as a trading company in 1998, everything has revolved around dry ice for us since 2007. Alexander Böhm has been managing the company since 2021 under the name Pro Trockeneis GmbH. In August 2021, the company moved from Wachtberg near Bonn to our new headquarters in Rheinbach.

Our corporate culture, like us, has grown slowly. Three pillars have stood out in particular.
Independent – Sustainable – Together
In 2007, we were looking for a reliable dry ice supplier and, as a small company, we did not find one. In order to remain as independent as possible from large dry ice suppliers, Werner Böhm decided to start his own production. With a pelletiser and a delivery vehicle at that time, the dry ice production started and with it the possibility to reliably supply our customers with high-quality dry ice.


Over the next few years, the company continued to develop and dry ice production was joined by dry ice boxes and
dry ice production machines. And here, too, the focus was on independence from large companies.

But a company does not grow alone. A one-man business quickly became a family business and the family grew larger with each new team member. Together with our now 12 employees, we work every day to reliably supply our customers. We also succeed in this thanks to the good cooperation with suppliers and partners. Because only together with you can we achieve our goals.

The focus of our next projects is on sustainability. When we built our production machines, it was already important to us to design them robustly to ensure a long service life. With rising raw material prices, we looked around the market and found what we were looking for in Denmark. Our partner’s reliquefaction facilities ensure that we can reliquefy 45% of the CO² gas that would otherwise be lost. In this way, we not only conserve resources, but also save on journeys, and we heat our production hall with the waste heat from the machines.

We have set ourselves a lot of goals for the next few years, such as generating electricity from alternative energies and zero-emission production, but also the further training of our employees. A first step in electricity generation was taken as early as summer 2022 with a photovoltaic system on the roof of our production hall.
