Flamco - 1000 Ltr - Flexcon Expansion Vessel - 6 barFlamco Flexcon Expansion Vessel - 1000Ltr - Engineered for EN 12828 heating and chilled-water systems, this Expansion Vessel stabilises sealed system pressure by absorbing thermal expansion in LPHW/CHW applications.
Maximum working pressure: 6.0 bar.
Vessels in accordance with EN13831.
Suitable for systems with a maximum system temperature of 120 °C.
Minimum / maximum temperature diaphragm: -10 / 70 °C.
Suitable for addition of glycol-based anti-freeze up to 50%.
A flexible rolling diaphragm with a ribbed profile prevents sticking and encourages inflow at the slightest pressure rise, while a nitrogen pre-charge helps maintain set pressure longer. The uncoated connection thread supports quick, watertight installation.
- Rolling-diaphragm design for smooth expansion control
- Nitrogen pre-charge for extended pre-pressure retention
- Top-quality steel with epoxy-powder finish
- Factory tested for reliability
Built for long service life in domestic, commercial and industrial plant rooms, with continuous medium temperatures from −10 to 70 C.
