50 liter expansion tank made for a solar collector system.

Design that can also be set on the ground.
Solar expansion tanks can withstand higher temperatures than traditional heating compared to tanks, and the membrane is more resistant to solar (antifreeze) liquid.
In solar collector systems, when sizing an expansion tank, in addition to thermal expansion, the possibility of steam formation must also be taken into account.
