CCT Chamber – ACC32 Water Fog Humidity – how it works

Some tests recommend high humidity conditions (95-100% RH) are created by spraying water as a fog, rather than by evaporation from a heated water bath. This option provides a second 100 Ltr/26 US Gal water reservoir, additional chamber mounted fog atomiser(s) and associated pumping equipment, to enable a water fog humidity environment to be created at user programmable times. This function works in much the same way that the standard salt spray mode of operation works, with many duplicate systems operating in similar ways, as described below. 

The control system fitted to Ascott CCT chambers enables the user to program whether water fog humidity is conducted alone, or in sequence with other climates, to form a cyclic corrosion test, for automatic execution by the chamber.
