Built for sealed heating and chilled-water circuits, the Flexcon M [10Bar] is a replaceable-bladder expansion vessel designed to stabilise system pressure in line with EN 12828.

It excels where static pressure and safety-valve setpoint differ significantly, helping maintain pre-pressure while reducing cycling. Supplied with a pressure gauge, height-adjustable feet and an inspection flange for straightforward servicing.

• Replaceable bladder for fast maintenance and long service life
• Delivered ready to install: gauge and adjustable feet included
• Inspection flange for internal access
• Robust steel vessel with durable epoxy-powder finish

Larger Flexcon M models (12008000 Ltrs) can be fitted with a Flexvent Super for enhanced air removal.

Flexcon intermediate expansion vessels to protect Flexcon expansion vessels on elevated temperature systems. The vessels are fitted in between the expansion vessel and the system return. System water flows from the installation into the top of the vessel. From the bottom of the vessel, significantly cooler water is fed into the expansion vessel.

Built for EN 12828 heating and chilled-water systems, Flexcon Premium Expansion Vessels stabilise pressure by absorbing thermal expansion in sealed LPHW/CHW installations.

The range introduces a lightweight TPO (thermoplastic polyolefin) diaphragm on 12–35 Ltrs models, combining high flexibility with very low permeability. Using up to 50% less material cuts raw-material use and transport energy, while FSC-certified packaging further reduces CO₂ impact.

• Sustainable design — lighter TPO membrane; FSC-certified packaging
• Long service life — 15-year warranty and factory functional testing
• Low permeability — helps pre-charge hold for longer
• Nitrogen filled — limits corrosion and pressure loss vs air

Construction features include a zinc-plated steel clench ring that evenly clamps the diaphragm for a perfect seal, pre-coated vessel halves (no clamp-ring corrosion or thermal shock to the diaphragm), a countersunk nitrogen valve protected by a recycled-plastic cover plate, and a ribbed, preformed rolling diaphragm that resists sticking. An uncoated taper water connection thread eases watertight installation; the vessel is finished in a gleaming epoxy-powder coat.
