Long periods under high temperatures (1,180°C) in pressurized chambers
(vacuum muffles) can shorten the heating resistance useful life. The S.A.L.V.

The metallic alloys used as heating resistance have chemical elements in its
composition that, when heated and in contact with air, create an oxide adherent
layerwhichprotectsthemfromoutwear.
In ceramic furnace muffles, the process for the oxide layer formation can be

TheexclusiveS.A.L.V.system,developedandpatentedbyEDG,promotesairflow
inside the quartz pipe that supports the muffle resistance. This flow renews and
maintains the protective oxide layer, increasing the useful life of the resistance at
hightemperatures.
This exclusive technological advance allowed EDG to extend the guarantee to 2

To endure the high temperatures involved in the processes, the sensor (termopar)
should be made of platinum which, on the other hand, is not adequate for low
temperatures and for the necessary speed for eliminating water during the
sinteringprocess.
Ahigh level software was developed to compensate theplatinum limitations in low
temperatures. Due to the characteristics of the sintering process, new thermal
insulating materials were used and an efficient ventilation system keeps the
