Lift-top furnaces have the advantage that they are highly accessible for charging. The heating from all four sides and the table provides for very uniform temperatures. The basic furnace is equipped with a fixed table under the hood. The system can be expanded by adding one or several exchangeable tables which can be driven manually or motorically. Another option is to remove the hood completely with a shop crane. In such cases, the furnace heating system has a plug-in power supply.

• Tmax 1200  °C
• Dual shell housing with rear ventilation for low shell temperatures
• Electrohydraulically driven hood with fixed table
• Five-sided heating from all four sides and from the table provides for a temperature uniformity up to ∆T 20 K according to DIN 17052-1
• Heating elements mounted on support tubes provide for free radiation and long service life of the heating wire
• Bottom heating protected by SiC tiles which provide for a level stacking surface
• Multilayer insulation consisting of lightweight refractory bricks backed by special insulation
• Long-life ceiling design with fiber insulation
• Manual exhaust air flap on the furnace roof
• Over-temperature limit controller with manual reset for thermal protection class 2 in accordance with EN 60519-2 as temperature limiter to protect the furnace and load
