Cupellation Furnace Type FCOPP
The cupellation furnace removes all non-precious metals from samples of precious alloy to be assayed.
The silicon carbide resistances give out a maximum power of 3 kW on each of the 3 resistance groups for the FCOPP/A and 4 kW for the FCOPP/B. The power on each phase is electronically controlled which avoids manual regulation and increases the life of the resistances.
The new FCOPP furnace has a stainless steel structure with insulated walls and a cooling system consisting of 3 fans that allow the flow of hot air towards the upper part of the furnace, thus facilitating suction.
The FCOPP/A version has a slightly larger muffle that allows for 6 cupels per row, instead the muffle of the FCOPP/B version allows the placement of 10 cupels per row. The door of the muffle is also equipped with an articulated quadrilateral system which allows the installation of an electric motor for automatic opening.
With this new thermal insulation, the external surface temperature in the critical points does not exceed 70-80 °C.
