Flamco - 25 Ltr - Flexcon Solar Expansion Vessel - 2.5-8 BarPurpose-built for solar thermal circuits, the Flexcon Solar 8/2.5 [8Bar] expansion vessel supports sealed systems in line with EN 12828, keeping pressure stable in high-temperature applications.
A preformed butyl rolling diaphragm with extremely low permeability helps retain pre-charge, while a nitrogen fill limits corrosion and pressure loss. The clench ring clamps the diaphragm evenly to prevent damage, and a ribbed profile avoids sticking for instant inflow. An uncoated connection thread aids watertight installation; the steel vessel is finished in a gleaming epoxy-powder coat and factory tested.
- Solar-ready expansion vessel for sealed systems
- Butyl rolling diaphragm with very low permeability
- Nitrogen pre-charge for longer pressure stability
- Clench ring construction for a robust, uniform seal
For 880 Ltrs models: both halves are coated before assembly to protect the clamp ring, and the nitrogen valve is countersunk and covered. Continuous medium temperature range −10 to 110 C.
