KSL-1500X-S-H 1500°C Hybrid Furnace with 1.7L Muffle Chamber and 2″ Mullite Tube, Programmable PID Controller
The KSL-1500X-S-H hybrid furnace addresses the need for flexible high-temperature processing in research and material development laboratories. It combines a 1.7-liter muffle furnace chamber with a 2-inch diameter mullite tube furnace capability, enabling users to perform both box furnace and tube furnace applications within a compact footprint. This dual functionality supports diverse workflows such as sintering, annealing, and vacuum or controlled atmosphere treatments.
The furnace features a drop-down door design for convenient sample loading and includes gas inlet and venting ports to facilitate oxygen or inert gas environments. When configured as a tube furnace, a 2″ mullite tube (closed at one end) is inserted through a front door opening, supported by a vacuum flange assembly with valves and ports for gas flow and vacuum application. The system can achieve vacuum levels down to 10-5 torr with a turbo pump, suitable for advanced material processing under reduced pressure.
Wichtigste Merkmale
- Dual-function design: 1.7L muffle furnace chamber (120x120x120 mm) and 2″ tube furnace capability.
- SiC U-shaped heating elements (4 pcs) enabling continuous operation at 1400°C and short-term peak at 1500°C.
- Programmable PID temperature controller with auto-tune, 30-segment ramp/cool/dwell programming, and ±1°C accuracy.
- Gas inlet and venting ports for controlled atmosphere processing including oxygen and inert gases.
- Vacuum flange set with KF25 port, mechanical vacuum gauge, and valves for gas and vacuum control.
- Heating rate adjustable up to 20°C/min (recommended ≤10°C/min for longevity).
- Includes a 2″ fibrous alumina thermal block installed in the front door for thermal insulation.

Typische Anwendungsbereiche
This hybrid furnace is suitable for sintering ceramics, annealing metals, vacuum heat treatments, and controlled atmosphere processing. Its ability to switch between muffle and tube furnace modes makes it ideal for labs requiring flexible thermal processing with precise temperature control and atmosphere management.
Hinweise zur Konfiguration und zum Betrieb
The furnace includes the mullite tube, vacuum flange set with valves and gauge, and a fibrous alumina thermal block. Power cable is supplied without a plug; users must install a plug compatible with their local power standards or select an optional plug. Optional accessories include a laptop with LabVIEW-based temperature control software and wireless remote control for extended operation range.
To maintain furnace longevity, it is recommended to limit heating and cooling rates to 10°C per minute. Normal wear such as small refractory ceramic cracks may occur and can be repaired with alumina coating. Heating elements may require replacement over time due to performance degradation.
