Overview
FMU-18 is a laboratory muffle furnace designed for controlled-atmosphere high-temperature processing up to 1200 °C. The rectangular chamber (400×300×300 mm) uses three-sided resistance heating and PID temperature control to deliver stable ramps and ±1 °C regulation. A vacuum-sealable chamber with dedicated inert-gas ports supports N2, Ar, O2 and other non-reactive gases. Multi-layer ceramic-fiber insulation and a rigid steel enclosure reduce heat loss for continuous laboratory or pilot operation.

Key advantages

• Precise process control: PID regulation with Type K thermocouple feedback and programmable multi-segment profiles for repeatable cycles.
• Safe, standards-oriented design: built-in over-temperature alarm, temperature-deviation protection and automatic shutdown for operator and sample safety.
• Efficient thermal management: multi-layer ceramic insulation and sealed door design to minimize thermal losses during continuous runs.

Features

• Digital display and programmable controller with multi-step profiles.
• Three-sided heating (left, right and top) for improved temperature uniformity.
• Adjustable heating rate 0–20 °C/min (≤10 °C/min recommended for best repeatability).
• Compatible with controlled gas atmospheres (O2, N2, Ar, CO and other inert gases) and vacuum sealing (cold state up to −0.1 MPa).
• High-efficiency ceramic-fiber insulation and robust steel housing.
• Type K thermocouple; temperature control accuracy ±1 °C.
• Built-in safety alerts: over-temperature, phase-loss and system fault warnings.
• Durable sealed door with silicone sealing strips.

Applications

• Laboratory and pilot heat treatments: sintering, calcination, annealing, carbon treatments and lithium-battery material processing.
• Material testing, thermal analysis, ash/combustion tests and R&D high-temperature workflows.

Standard accessories

• 1 pair of crucible tongs
• 1 pair of heat-resistant gloves
