Altecnic Stainless Steel Expansion Vessel 50 Litre SSV50C

The 50 litre Stainless Steel Expansion Vessel is manufactured by Altecnic and forms part of the Altecnic expansion vessel range. It absorbs the volume change of water as a heating or hot water system heats and cools, limiting pressure fluctuation within the system. The vessel body is constructed in stainless steel.

• The pressure relief valve discharges water repeatedly during normal heating cycles
• System pressure rises quickly when hot and drops when cold, with frequent topping up needed
• Water is found at the valve on the vessel, indicating a failed internal diaphragm or bladder
• The vessel feels heavy or waterlogged when tapped, showing it is full of water
• Visible corrosion, weeping or deformation of the vessel shell

• Confirm the existing vessel capacity matches the 50 litre specification required for the system
• Check the connection size and thread on the existing vessel against the new unit
• Verify the available space and mounting arrangement will accept the vessel
• Confirm the pressure rating required by the system is met by the vessel
