Heating furnace LHTCT 01/16

laboratorymufflestainless steel

Overview
Laboratory muffle furnaces available with Tmax 1550 °C or 1600 °C. SiC rod heating provides fast heating rates and proven durability in periodic laboratory use. Typical empty‑furnace heating times to near Tmax are 25–30 minutes depending on model and operating conditions. These furnaces are intended for defined laboratory processes and must be used according to the operating instructions.

Standard equipment

• Tmax options: 1550 °C or 1600 °C; recommended working temperature up to 1500 °C to limit wear
• Muffle chamber with high‑quality fibre insulation and SiC heating rods arranged on both sides
• Dual‑shell housing in textured stainless steel with additional fan cooling for low external surface temperature
• Insulation materials without CLP categorization (EC Reg. 1272/2008)
• Door options: flap door (LHTC) usable as work platform or lift door (LHTCT) with hot side away from operator (LHTCT 01/16 only with lift door)
• Switching system with solid‑state relays, power matched to SiC rods
• Easy replacement of heating rods
• Adjustable air inlet opening and exhaust opening in the roof
• Controller C550 with touch operation (10 programs × 20 segments)
• NTLog Basic for process data recording via USB (for Nabertherm controllers)

Additional equipment

• Over‑temperature limiter with adjustable cut‑out temperature for furnace and load protection
• Protective gas connection for purging with non‑flammable process gases (not gas‑tight)
• Manual or automatic gas supply systems
• VCD software package for process control, monitoring and documentation

Technical table (selected models)
Model | Tmax (°C) | Inner dimensions W × D × H (mm) | Volume (l) | Outer dimensions W × D × H (mm) | Connected load (kW) | Electrical connection | Weight (kg) | Heating time (min)
LHTCT 01/16 | 1550 | 110 × 120 × 120 | 1.5 | 340 × 335 × 485 | 3.5 | 1‑phase | 20 | 30
LHTC(T) 03/16 | 1600 | 120 × 210 × 120 | 3.0 | 415 × 545 × 490 | 8.5 | 3‑phase | 38 | 30
LHTC(T) 08/16 | 1600 | 170 × 290 × 170 | 8.0 | 490 × 625 × 540 | 12.5 | 3‑phase | 58 | 25
Notes: external dimensions vary with additional equipment; +255 mm max for LHTCT when open. Heating times refer to empty closed furnace up to Tmax −100 K; connected load refers to standard configuration and may increase with options.

Application & features
Designed for laboratory processes such as sintering, annealing and thermal treatment where rapid temperature ramp and reproducible atmosphere control are required. Variants with flap or lift doors adapt to handling needs. Safety and process options (over‑temperature limiter, protective gas purge, process documentation) support controlled operation and traceability.
