Elko-flex EDER WE
The Elko-flex EDER maintenance unit is a connection accessories kit for expansion vessels to ensure proper integration into the system and it includes all necessary functions for maintenance.
Expansion vessels with constant primary pessure have to be proved regularly, to ensure a long-term proper function of the vessel and the system (recommended yearly, maximum every two years). Thereby the primary pressure in the vessel at the waterside pressureless condition has to be checked and to be corrected if necessary. Therefore it must be possible to seperate the vessel from the system by an armature so that it can be emptied.
