air conditioning units for highly efficient heating and cooling

Increasingly better insulated buildings shorten the heating period to a few months per year. On the other hand, internal loads ensure that these buildings need to be cooled more and more. The air conditioning technology of Erich Keller AG is based on highly efficient convector heaters which can be operated according to the change-over principle in summer and winter. Compared to a conventional air conditioning unit or a normal air conditioning system, Rio-Therm can cool almost all year round with free cooling due to the near-room flow temperatures of 20°C for cooling and 26°C for heating. Our designers, carpenters and technicians fit the devices into every building in tailor-made and shapely fashion.
