The GT-HR tanks are conventional diaphragm-type expansion vessel ranging from 8 to 1000 litres for 6 bar working pressure for closed heating systems and chilled water applications. These tanks can be incorporated in an expansion system in a tiny household or a large multi-storey building.
GT-HR tanks can be used with any Grundfos pump.
The GT-HR tanks are available in sizes ranging from 8 to 1000 litres and are suitable for vertical installation. The tanks have a non-replaceable diaphragm that is pre-charged with nitrogen (1.5 bar). The tanks have a non-toxic butyl rubber diaphragm, dividing the tank chamber into two compartments. The upper compartment contains compressed nitrogen. The lower compartment has a liner of polypropylene (PP) and is filled with water from the pump.
