1Recommended working temperature for processes with longer dwell times is 1050 °C
2External dimensions vary when furnace is equipped with additional equipment. Dimensions on request.
3Heating time of the empty and closed furnace up to Tmax −100 K (connected to 230 V 1/N/PE)
4Temperature uniformity of +/− 5 K with closed fresh-air inlet in empty work space according to DIN 17052-1 at working temperatures above 800 °C see page 77
5The connected load refers to the standard furnace and may increase for a furnace with additional equipment. For furnaces with connection options for multi-range voltages, the connected load applies to the highest permissible connected voltage.
