Reliable and correctly dimensioned diaphragm expansion vessels: How do you ensure that a sudden pressure surge does not damage the sensitive components of the heating system in the middle of the coldest weeks of winter?
What does a professional need to know about diaphragm expansion vessels? The purpose of a diaphragm expansion vessel is to compensate for the thermal expansion of water in closed heating and cooling systems. Correctly selected and pre-pressurised diaphragm expansion vessels prevent the system pressure from rising uncontrollably, protecting valves, piping and automation components from damage. Helvis Express supplies high-quality expansion vessels directly from a Finnish warehouse for professionals' needs.
