Purpose-built for EN 12828 heating and chilled-water systems, this multifunction sealed-system unit combines automatic expansion control, pressurisation, deaeration and make-up in a single package.

A pressure-step degassing process—using a controlled pressure drop and patented PALL-ring media—removes dissolved gases even at equilibrium. A replaceable butyl bladder stores the expansion fluid at atmospheric pressure. Supplied with Flexvent Super, height-adjustable feet and a weight-capacity sensor.

• All-in-one functionality — expansion, pressurisation, deaeration and make-up
• Pressure-step deaeration with PALL-ring technology
• Replaceable butyl bladder — easy maintenance and long service life
• Delivered complete — Flexvent Super, adjustable feet, weight-capacity sensor

Designed for commercial, industrial and residential sealed LPHW/CHW installations requiring efficient air removal and stable operating pressures.

Flamco Flexcon Expansion Vessel - 110Ltr - 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: 10.0 bar.

Vessels in accordance with EN13831.

Suitable for systems with a maximum system temperature of 120 °C.

Minimum/maximum temperature diaphragm: -10 / 90 °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.
