Expansion vessel REFIX DE-25, 25L, 10 bar / 70 degrees, connection

• Pressure maintaining devices perform three important functions:

• Maintaining the pressure at each point in the system within permissible limits.

• This means both protecting against exceeding the maximum permissible operating pressure and against falling below the minimum pressure, in order to avoid vacuum, cavitation and evaporation.

• Compensating for changes in the volume of water in the system caused by temperature changes.

• Compensating water losses resulting from system operation in the form of an appropriate water resource.

• Refix DE expansion vessels are used in installations that do not meet the requirements of DIN 1988, e.g.

• for potable water installations, fire protection systems, underfloor heating, industrial and geothermal systems.
