## Summary description

VAREM LR CE expansion vessel, 35 L capacity, with 3/4" connection, designed for gas systems up to 6 bar. This diaphragm-type pressure vessel provides hydraulic compensation and protects system components from pressure fluctuations. Suitable for domestic and light commercial gas installations, boiler circuits and heating systems requiring a 35 L accumulator vessel.

## Long description

The VAREM LR CE 35 L expansion vessel with a 3/4" connection is a diaphragm-type accumulator designed for gas systems operating up to 6 bar. With a net capacity of 35 liters, this pressure vessel provides hydraulic compensation to absorb pressure variations, reducing stress on pipes, valves and other system components. It is intended for domestic and light commercial gas installations, boiler circuits and heating systems that require a compact 35 L expansion vessel to stabilize system pressure and improve operational reliability.
Advantages
This expansion vessel uses a pre-charged diaphragm to separate the gas and fluid sections, ensuring rapid response to pressure changes and minimizing fluid loss. The 3/4" threaded connection simplifies installation on standard gas and heating fittings. Constructed to meet CE requirements for LR series vessels, it is suitable for use in systems with working pressures up to 6 bar and offers a compact footprint that fits into tight mechanical spaces.
Suitable for
Domestic gas installations and residential boiler systems
Light commercial heating systems and small commercial boiler circuits
Systems requiring hydraulic compensation and protection against pressure surges
Installations where a 35 L diaphragm expansion vessel is specified
Key specifications
Type: diaphragm (membrane) expansion vessel
Net capacity: 35 liters
Connection size: 3/4" threaded inlet
Maximum working pressure: up to 6 bar
Application: gas and heating system hydraulic compensation
Compliance: designed to meet CE requirements for LR series vessels
How to use
Install the expansion vessel vertically or horizontally according to available space and installer recommendations, ensuring the 3/4" connection is compatible with the system piping. Before commissioning, check and adjust the pre-charge pressure of the gas side to match the system static pressure, following the manufacturer's guidance for initial pressure settings. Secure the vessel to prevent movement, connect to the system at an appropriate location such as near the boiler or pump station, and test the system for leaks and correct pressure compensation during initial operation.
Usage recommendations
Regularly inspect the vessel and fittings for signs of corrosion, leaks or diaphragm failure. Verify the pre-charge pressure periodically, particularly after maintenance or system draining, and replace the vessel if the diaphragm shows loss of elasticity or if the unit fails to maintain system pressure within expected ranges.
