KSL-600X-AC-5S Five-Side Heating Atmosphere Controlled Muffle Furnace with 216L Capacity and 600°C Max Temperature
The KSL-600X-AC-5S furnace is engineered for laboratory applications requiring controlled atmosphere heat treatment with precise temperature uniformity. It supports vacuum or inert gas environments, enabling oxidation-sensitive or reducing atmosphere processes up to 600°C continuously. This furnace is ideal for materials research, sintering, annealing, and other thermal processes demanding stable and uniform heating.
The furnace chamber measures 609 × 609 × 609 mm, providing a total volume of 216 liters. It employs five-sided heating elements—right, left, top, back, and front—to achieve a uniform temperature zone of 500 × 500 × 500 mm within ±3°C at 600°C. The heating elements are Kanthal Fe-Cr-Al resistance wires embedded in high-quality alumina fiber insulation, ensuring efficient thermal performance and durability.
Key Features
- Hermetically sealed chamber supporting vacuum and controlled inert, reducing, or oxidative atmospheres.
- Five-sided heating design for superior temperature uniformity and process consistency.
- PID temperature controller (FA-YD518P-AG) with 30 programmable segments and ±1°C control accuracy.
- Integrated vacuum system with mechanical and digital gauges, achieving vacuum levels below 0.1 torr after baking.
- Gas flow control via two 10 L/min float flow meters for precise atmosphere regulation.
- Includes a 960 L/min rotary vane vacuum pump and a 16 L/min recirculating water chiller for temperature and system stability.
- Optional Eurotherm temperature controller upgrade for enhanced control with ±0.1°C fluctuation.
