1700°C & 1800°C BOTTOM LOADING FURNACES

General Features

Maximum operating temperatures of 1700°C and 1800°C.

Three chamber sizes available.

Convenient loading of chamber through electrically actuated lift mechanism.

Superior sample uniformity is obtained by positioning elements on all sides of hexagon shaped chamber.

All standard 1700°C and 1800°C BLF furnaces are fitted with 3216P1 programmer and a separate independent over-temperature protection control.

Elevator hearth design provides safe and smooth loading and unloading of delicate loads.

Fast heating and cooling of the sample is achieved by raising or lowering the sample from the furnace chamber.

Long-life molybdenum disilicide heating elements are suitable for intermittent or continuous operation.

Advanced high temperature, high strength hot face insulation is combined with graded low thermal mass insulation to improve thermal performance and energy efficiency.

Positive break safety switch isolates power to the heating elements when hearth is lowered.

Chamber vent provides for process exhaust.

Large diameter heating elements greatly reduce potential for mechanical breakage.

Low temperatures of outer case and critical components are provided through fan cooling.

Molybdenum disilicide element resistance does not change with usage, providing no restriction on placement of a new element in circuit with older elements.

Optional gas containment cover allows processing under high purity inert atmospheres.

Optional protective alumina liner is available for aggressive processes that may harm elements or insulation materials.
