The steam humidifier Nordmann AT4 is a pressureless steam generator
that utilizes an electrode heating. The steam humidifier Nordmann AT4 is
designed for air humidification via a steam distributor (steam distribution
pipe, fan unit or steam distribution system MultiPipe).

Steam generation
Any time steam is requested, the electrodes are supplied with voltage via
main contactor. Simultaneously, the inlet valve opens and water enters the
steam cylinder from the bottom via water cup and supply line. As soon as the
electrodes come in contact with the water, current begins to flow between
the electrodes, eventually heating and evaporating the water. The more the
electrode surface is exposed to water, the higher is the current consumption
and thus the steam capacity.
