Description

The Flamco - 500 Ltr - Contraflex Expansion Vessel - 6 Bar is a pressure vessel designed to support pressure stability within the system and reduce rapid cycling.

With pressure duties up to 6 Bar, it is built to help protect connected equipment and smooth system operation.

Tailored for sealed heating and chilled-water circuits, the Flamco Contraflex Expansion Vessel stabilises system pressure in accordance with EN 12828 using a durable rolling-diaphragm design.

A nitrogen pre-charge maintains set pressure for longer, while each vessel is factory tested for reliability. The flexible rubber diaphragm's rolling action delivers smooth expansion control across demanding duty cycles.
