Choosing the right device for heating area:

For the correct unit selection, the individual situation is important. Individual counseling is done by trained GRANDER® consultant. Circulation revitalisers should not be used in drinking water!

Installation in Heating Area:

The installation should be done, particularly in high temperature systems, in return flow after a possible dirt separator and to guarantee a problem-free system ventilation in a vertical pipe.
