## Summary description

VAREM LR CE expansion vessel, 12‑liter capacity, 3/4" gas connection and maximum pressure 6 bar. Designed for closed heating and domestic hot water (DHW) systems to absorb pressure fluctuations and protect system components.

## Long description

VAREM LR CE 12L expansion vessel with a 3/4" gas connection and a maximum working pressure of 6 bar is designed for closed heating and domestic hot water (DHW) systems. The vessel contains a gas‑charged diaphragm that separates the heating fluid from the compressed gas, allowing it to absorb pressure fluctuations, compensate for thermal expansion and protect pumps, valves and piping in compact boiler or wall‑mounted installations. Its 12‑liter nominal capacity suits small to medium residential systems and routine maintenance tasks.
Advantages
The gas‑charged diaphragm ensures reliable separation between fluid and gas, preventing corrosion and contamination. With a maximum pressure rating of 6 bar and a standard 3/4" gas connection, the vessel is compatible with many domestic and light commercial installations. Its compact design facilitates installation in tight spaces near boilers or hot water cylinders, while the nominal 12 L volume provides effective expansion control in small heating circuits.
Suitable for
 Closed central heating systems in dwellings
 Domestic hot water (DHW) systems with small to medium storage
 Compact or wall‑mounted boilers and combination units
 Replacement and routine maintenance of existing expansion tanks
Key specifications
 Nominal volume: 12 liters
 Connection type: 3/4" gas threaded connection
 Maximum working pressure: 6 bar
 Internal separator: gas‑charged diaphragm
 Application: closed heating and domestic hot water systems
 Mounting: suitable for wall‑mounted or compact boiler installations
How to use
Install the expansion vessel on the system return line or at the location recommended by the boiler manufacturer, using the 3/4" gas connection. Before commissioning, ensure the pre‑charge of the gas side matches the system requirements and adjust the initial pressure according to the cold static pressure of the heating loop. After installation, bleed air from the system and verify there are no leaks at the connections. Periodically check the pre‑charge and system pressure as part of routine maintenance to maintain correct expansion compensation.
Usage recommendations
Verify compatibility with system maximum pressure and initial charge requirements prior to installation. Use appropriate seals and tools for the 3/4" gas connection, and follow local regulations and manufacturer guidance when replacing or servicing expansion vessels.
