Softened water flows into the steam generator. The feed water pump feeds the water from the tank or directly from the line into the pressure vessel. The electronic water level control regulates the water level inside the pressure vessel by means of level electrodes or a float switch (depending on configuration), as well as the activation of the heating and protects the heating elements against damage due to malfunctions (low water level protection). The electric heating elements heat and vaporise the water. The heating is activated in stages (depending on configuration) in order to prevent overloads in the power network. The vapour pressure is indicated by the manometer. The pressure control device switches the heating off, when a value of 500kPa (5bar) is reached and switches it back on at 450kPa (4.5bar). The vapour is extracted through the steam supply valve. The safety relief valve prevents overpressure and is activated at 550kPa (5.5bar).
Any condensate accumulating in the steam line and the consumer can be returned to the water circulation via the condensate inlet of the heat exchanger (optional equipment).
