Structure of closed systems from JUMAG
The JUMAG condensate pressure vessel has all functions of the JUMAG feed water container for steam boilers (e.g. water level control for fresh water supply and steam pre-heating for degassing).
Furthermore, the JUMAG condensate pressure vessel contains an overflow valve in addition to a relief valve. This prevents frequent opening of the relief valve at excess pressure increase. Degassing of the fresh water can be controlled in this way as well.
As the feed water is routed into the steam boiler at a much higher temperature, the temperature-resistant boiler feed pump is used.
Because this is a pressure vessel, it is subject to TÜV approval and regular monitoring.
Possible uses of closed systems
Closed systems are particularly worthwhile for steam systems:
