(LHT 08/17)

LHT 02/16 - LHT 08/18
Designed as tabletop models, these compact high-temperature chamber
furnaces have a variety of advantages. The first-class workmanship
using high-quality materials, combined with ease of operation, make
these furnaces all-rounders in research and the laboratory. These
furnaces are also perfectly suited for the sintering of technical
ceramics, such as zirconium oxide dental bridges.
• Tmax 1600 °C, 1750 °C, or 1800 °C
• High-quality molybdenum disilicide heating elements
• Furnace chamber lined with first-class, durable fibre material
• Housing made of sheets of textured stainless steel
• Dual shell housing with additional fan cooling for low surface
temperature
• Furnace sizes of 2, 4, or 8 liters
• With lift door, whereby the hot side is away from the operator
• Adjustable air inlet
• Exhaust air opening in the roof
• Type B thermocouple
• Switching system with phase-angle firing thyristors (SCRs)
Additional equipment
??• Over-temperature limit controller with manual reset for thermal protection
class 2 in accordance with EN 60519-2 as temperature limiter to protect the oven
and load
• Square saggar for charging of up to three layers
• Spacer recommended to be placed under the bottom saggar for better temperature
uniformity
• Protective gas connection
• Manual or automatic gas supply system
