  • Page 11: Functional Description

    Functional description The steam humidifier Nordmann ES4 is a pressureless steam generator that utilizes an electrode heating. The steam humidifier Nordmann ES4 is designed for air humidification via a steam distributor (steam distribution pipe, fan unit or steam distribution system MultiPipe).
  • Page 12 Upon reaching the requested steam capacity, the inlet valve closes. If the steam generation decreases below a certain percentage of the required capacity, due to lowering of the water level (e.g. because of the evapora- tion process or drainage), the inlet valve opens until the required capacity is available again.
