Heat treatment oven L 9/11/SKM

for general purposeslaboratorymuffle

Product overview
The L 9/11/SKM muffle furnace is designed for heat treatment of aggressive substances. The furnace chamber features an embedded ceramic muffle with heating embedded on four sides for very good temperature uniformity and strong protection of the heating elements. The muffle surface is smooth and nearly particle-free; the furnace door can be fiber-insulated. Controller B510 (touch) and NTLog Basic for process data recording via USB are available.

Standard equipment

• Tmax 1100 °C
• Muffle heated from four sides (embedded heating)
• Furnace chamber with embedded ceramic muffle, high resistance to aggressive gases and vapours
• Dual-shell textured stainless steel housing with additional fan cooling to reduce external surface temperature
• Use of insulation materials not classified under EC Regulation No. 1272/2008 (CLP)
• Optional flap door (L) usable as work platform or lift door (LT) with hot surface facing away from the operator
• Adjustable working air inlet in the door
• Exhaust air outlet in the rear wall
• Controller B510 with touch operation (5 programs × 4 segments)
• Solid state relays for low-noise operation
• NTLog Basic for Nabertherm controller: process data recording via USB flash drive

Additional equipment

• Chimney, chimney with fan or catalytic converter
• Over-temperature limiter with adjustable cutout temperature
• Protective gas connection for purging with non-flammable process gases (non gas-tight; not combinable with some chimney options)
• Manual or automatic gas supply system
• Port for thermocouple in rear wall or furnace door
• Process control and documentation via VCD software package
