These chamber ovens are available for maximum working temperatures of 260 °C or 450 °C. They are suitable for numerous processes such as pre-heating of moulds, ageing or drying. The version suitable for temperatures up to 450 °C is recommended for Heat Soak testing of Toughened Safety Glass (TSG). During a Heat Soak Test in accordance with EN 14179-1 the panes are exposed to a temperature of 290 °C for at least four hours in order to transform nickel sulfide inclusions and hence to prevent the pane from breaking spontaneously later. The documentation of the heat treatment process is strongly recommended. Program entry, visualization and the documentation of the process are achieved by means of the PLC-control in combination with the powerful Nabertherm Control Center (NCC), which registers and archives the temperatures at different measuring points on the pane.
