Sintering furnace LHT 03/17 D

heatinglaboratoryfor dental laboratories

Product overview
The LHT ../17 D sintering furnaces are designed for dental laboratories for sintering translucent zirconia bridges, crowns and full arches at temperatures up to 1650 °C. Special molybdenum disilicide (MoSi2) heating elements minimise chemical interaction between the charge and furnace components. Depending on model, one sintering cycle yields approx. 30 (LHT 01/17 D) or 75 (LHT 03/17 D) single crowns.

Product description
Compact high-temperature furnaces for routine dental sintering tasks. Long service life and flexible programming allow adaptation to most recommended sintering curves from leading zirconia manufacturers. Units support program import via USB and mobile monitoring.
