Built for sealed potable hot and chilled water systems in domestic and commercial settings, these Potable Water Expansion Vessels stabilise pressure by absorbing thermal expansion for safe, reliable operation.

A nitrogen pre-charge helps retain set pressure longer, while a single threaded steel connection with plastic insert provides a durable, non-flow-through design. Suitable for central heating, cooling and tap water applications (not for solar collector circuits).

• Nitrogen gas filling for longer pre-charge retention
• Single threaded steel connection with plastic insert (no flow-through)
• Potable use supports domestic hot/chilled water
• Heating & cooling compatible for sealed systems

Designed for long service life with broad operating limits and glycol tolerance for demanding installations.

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.

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. Capacity 750 Ltr.
