In our production program, we are currently fully focused on the production of rotary regenerative heat exchangers. We care about quality, that is why we are still working on technological innovations and production patents, we are developing our own production equipment. After the modernization of CNC workplaces, we expanded the production capacity with a new production hall in 2020. By constantly modernizing our production lines, we increase the quality of our products and thus strive to become the leader of the European market with rotary heat exchangers.

We are regular participants in industry exhibitions and fairs and publish professional articles. Since 2019, we have been cooperating with the Czech Technical University in Prague, Faculty of Mechanical Engineering – Institute of Environmental Technology.

We provide comprehensive services from design, through implementation to servicing of our supplies and products.


KASTT holds Eurovent, TÜV SÜD and ČSN EN ISO 9001:2016 quality certificates for the production of rotary regenerative heat and moisture exchangers.
