Lenton EHF - 1700°C & 1800°C

Optimum temperature uniformity is obtained by the inclusion of molybdenum disilicide heating elements which are positioned around the walls of the chamber ensuring uniform heating of the sample. A combination of dense refractory brick hot face insulation and a secondary low thermal mass layer of insulation provides a robust chamber with an efficient utilisation of power.
The electrically operated elevator hearth ensures operator safety and prevents direct radiation of heat from the chamber walls. It also ensures smooth loading/unloading of the workpiece/crucible and allows both heavy and delicate loads to be handled easily. Overtemperature protection is fitted as standard.
The furnace can be adapted to accommodate an atmosphere other than air, by the use of an inverted alumina crucible in a groove in the hearth. Please contact us for further details.

Ideal for: melting of high purity glass, ceramic sintering & firing, thermal shock testing & firing in maintained atmospheres.
