Compensating vessel for solar systems, capacity 50 l 302496

Expansion vessel for solar systems, 50 l

Steel tank designed for vertical installation in solar circuits with antifreeze fluid. It compensates for the volume changes of the heating fluid caused by temperature variations — preventing excessive pressure rise in the system.

Capacity: 50 liters — suitable for medium‑power systems typical of residential solar‑thermal installations. Vertical mounting allows placement on the floor without wall fixing, simplifying installation and service.

Dimensions: 430 mm × 520 mm × 430 mm (length × depth × height). Weight: 12 kg — easy to transport and handle during installation.

Fittings on inlet and outlet: G3/4" — standard size, compatible with most components of Vaillant auroTHERM systems.

Pre‑charge pressure: 1.5 bar — as specified by the manufacturer, ensuring proper operation under normal conditions. Maximum working pressure: up to 10 bar — resistance to pressure spikes typical for solar systems.

Warranty: 5 years — confirmed by the manufacturer.

Installation, first start‑up, inspection and service must be carried out by authorized service personnel — a safety requirement for pressurised systems.
