High Temperature Bottom Loading Furnace - BLF

BLF bottom loading furnaces use an electrically operated elevator hearth, which as it rises into the furnace chamber, lifts the load into the heated zone.

This furnace provides the following advantages: easy loading of samples and uniform heating achieved by locating elements in all six side walls of the chamber.

The 1600 °C is ideal for sintering of zirconia dental crowns and frameworks. The silicon carbide heating elements will not cause discolouration of the zirconia.

• 1600°C, 1700°C & 1800°C maximum operating temperature
• 3 to 21 litre capacities
• Programmable EPC3016P1 controller
• Ideal for: sintering high performance ceramics, melting glass under high temperature or working with modified atmospheres
• Rapid heating & cooling cycles can be achieved through raising & lowering the hearth
• Electrically operated elevator hearth protects operator from the chamber's radiant heat
• Hearth cage with safety interlock
• Excellent temperature uniformity as a result of the hexagonal chamber
• Overtemperature protection to protect load or furnace during unattended operation
• 1600 °C model heated by silicon carbide elements
• 1700 °C & 1800 °C models heated by molybdenum disilicide elements
• Ethernet communications

• A range of sophisticated digital controllers, multisegment programmers and data loggers with digital communication options is available - more information about controllers
• Compatible crucibles
• Modified hearth for the introduction of gases into an inverted crucible (not gas tight)
• Radiation shutter
• Customised options including: adaptation to introduce thermocouple or stirrer through the chamber roof and rotating hearth
• Plasma sprayed alumina protection tube to protect heating elements from sample contamination
