Beschreibung
Zusammenfassung:	In a vaporiser for the developing device of a blueprinting machine, the heat exchanger converting the developer medium from the liquid state into the vaporous state consists of a tube coil and is arranged, together with the electric heater, in a housing consisting of a material of high heat storage capacity (and high thermal conductivity). In contrast to the known "quick-acting" control systems, the housing has such a large mass that the maximum possible demand for vaporous developer medium per unit time does not allow the temperature thereof in the tube coil to fall significantly below the desired vapour temperature and certainly not below the vaporisation temperature.
