وعاء التمدد RP250 8l De Dietrich S62753

The expansion vessel RP250 8l is a key element in closed-loop heating systems, absorbing excess water pressure as it expands when heated. With an 8-liter capacity, this vessel helps protect your boiler from overpressure and reduces the frequency of pressure relief valve activation. Proper sizing and installation of the expansion vessel are crucial for system stability. If you notice frequent pressure fluctuations or water dripping from safety valves, checking the expansion vessel should be a priority.
