replaceable diaphragm?\u003c\/h4\u003e\n\u003cp\u003eLarger capacity expansion vessels, used in communal or industrial installations, typically require periodic maintenance. The replaceable diaphragm significantly reduces costs and downtime, as there is no need to uninstall the entire vessel in the event of a diaphragm failure.\u003c\/p\u003e\n\u003ch4\u003eIs the dielectric union necessary on small models?\u003c\/h4\u003e\n\u003cp\u003eYes, the dielectric union isolates the vessel's steel from the copper or brass piping. This prevents galvanic corrosion (electrolysis) that occurs when dissimilar metals are in contact and facilitates drainage during future inspections.\u003c\/p\u003e\n\u003ch4\u003eHow should I adjust the \u003cspan data-math=\"3 \\text{ bar}\" class=\"math-inline\"\u003e3 bar\u003c\/span\u003e pre-charge?\u003c\/h4\u003e\n\u003cp\u003eThe \u003cspan data-math=\"3 \\text{ bar}\" class=\"math-inline\"\u003e3 bar\u003c\/span\u003e pre-charge pressure is the factory setting.
