Flamco Heating Expansion Vessels 8,12,18,25,35 litre System Sealed Kit Bracket

Flamco Contra-Flex Expansion Vessels 8, 12, 18, 25 and 35 litre (Baseflex) + System Sealed Kit Bracket For sealed heating and chilled water (cooling) installations. When the temperature in the installation rises, the system water will expand.

For sealed heating and chilled water (cooling) installations.

When the temperature in the installation rises, the system water will expand. The ‘expansion water’ is stored temporarily in the expansion vessel to keep the pressure in the installation at the correct level. Each vessel is factory tested.

The diaphragm is clamped between two vessel halves, preventing mechanical damage to the diaphragm or vessel halves during use. Compared to other bladder type vessels, the clamp ring construction cuts the air to water diaphragm surface ratio in half, resulting in a much lower permeability of the gas charge, a greater reliability and overall life expectancy of the vessel.
The thread of the system connection is uncoated, ensuring problem free connection.
