## Long description

The DNM Denko expansion/overflow tank SDNM0034 is designed for closed liquid heating and boiler systems to manage thermal expansion and collect excess fluid. Intended for integration with compatible burners and boilers, this tank helps maintain system pressure balance and reduce the risk of leaks or overflow by providing a dedicated space for expanded liquid. The product is suitable for professional heating installations and replacement of worn or undersized expansion vessels.
Advantages
The expansion/overflow tank offers a compact solution for handling thermal expansion in closed heating circuits, reducing stress on pumps, valves and pipe joints. Its design supports consistent pressure buffering and temporary accumulation of surplus liquid, which helps prevent frequent triggering of safety valves. The unit is compatible with standard heating system connections and is made to operate continuously under typical boiler system temperatures and pressures.
Suitable for
 Closed liquid heating systems with burners or boilers

How to use
Install the expansion/overflow tank in accordance with system layout and local plumbing codes, ensuring proper orientation and secure connections to the heating circuit. Connect the tank to the system at a point where it can receive expanded fluid from the circuit; typically this is near the boiler or at a return line. Verify that all valves, fittings and mounting brackets are tightened and that the tank is supported to avoid strain on pipework. After installation, pressurize and bleed the system according to the boiler manufacturer's instructions and check for leaks. Monitor system pressure during initial operation and adjust as required to achieve stable performance.
Usage recommendations
Use the tank with compatible heating fluids and maintain regular inspection intervals to check connections and pressure. Replace the unit if signs of leakage, corrosion, or loss of function occur. For optimal performance, follow the boiler or burner manufacturer's guidelines regarding system pre-charge, working pressure range and maintenance procedures.
