Prodmax - expansion vessel for central heating systems - complete with valve

The expansion (expansion) vessel with a self-draining valve are overflow tanks made of acid-resistant steel, tightly welded and additionally sealed at the edges with silicone. They are used as expansion tanks for open systems, e.g. central heating, where the losses are automatically replenished by opening the float valve and allowing liquid. It works in a similar way to a bathroom toilet.
