About Cooll
Our adventure
In 2008 we started research into sustainable heating and cooling based on adsorption technology. This research showed that the cooling application is technically difficult because it is an application for foreign markets, but that the heating application is very interesting. In 2009 Johannes Burger, Stefan van Uffelen and Robert Jan Meijer founded Cooll.


The first working system was built in 2011, which does not yet achieve the ultimate desired temperatures and power but demonstrates the principle.


The first wall-mounted model was developed in 2018. This set-up has now heated our office building for two winters. Parallel to this, we worked on the tooling to be able to produce the heat pumps.
Product development of the first product started in 2020 and the team expanded considerably.
