Treatment group thermaliQ

HB2 - fully demineralised water - quick and convenient

The treatment group thermaliQ:HB2 is designed for the full demineralisation of water of drinking water quality for the easy and quick initial filling or make-up water feed of heating circuits. The desaliQ:HB2 filling cartridge, which can also be purchased separately is included in the scope of supply and safely enclosed in the white plastic cylinder. The integrated conductivity measuring cell does your thinking for you and reliably monitors the water quality. In the case of a conductivity of less than 10 µS/cm, the green LED flashes, between 10 – 50 µS/cm the yellow LED lights up and from 50 µS/cm, the red LED signals that the full demineralisation unit needs to be replaced. The treatment group is complemented by a shut-off valve as well as vent valves.


With Grünbeck you always make the right choice.

Therefore, the treatment group is compatible with the other Grünbeck mixed bed cartridges. These can be connected effortlessly using the desaliQ connection adapter. The treatment group also serves as a retrofit option to already existing filling groups.
