High pressure alternative for use in sealed heating installations (acc. to EN12828) and chilled water (cooling) installations.
Diaphragm:butyl rubber.
The unique clench ring construction clamps the diaphragm between the two vessel halves.
Nitrogen gas filling for longer maintenance of pre-pressure.
The ribbed profile on the diaphragm prevents it from sticking to the inside wall of the vessel and ensures inflow of expansion water at the slightest increase in pressure.
Uncoated water connection thread ensures easy and water tight installation.
