KSL-1650X-GS65 Atmosphere Controlled Box Furnace with 65L Chamber, Up to 1650°C
The KSL-1650X-GS65 furnace is engineered for advanced material sintering processes requiring precise atmosphere control. Its spacious 16″x16″x16″ (65-liter) chamber accommodates sizable samples or batches, enabling uniform heat treatment under inert gas or oxygen environments. This furnace is particularly suited for research and development tasks involving high-temperature synthesis and processing of new materials.
The furnace structure incorporates a refractory muffle with water-cooled walls capable of withstanding positive pressures up to 0.06 MPa and vacuum levels down to -0.09 MPa. The sealed stainless steel chamber is insulated with energy-efficient 1800-grade fibrous alumina bricks, ensuring thermal stability and energy savings. Dual MoSi2 heating elements positioned on two sides of the chamber provide excellent temperature uniformity and can operate safely in both inert and oxygen atmospheres.
Key Features
- Heated chamber dimensions: 400 x 400 x 400 mm (16″x16″x16″), maximum volume 65 liters.
- Continuous operating temperature range from 800°C to 1600°C, with a maximum of 1650°C for up to 2 hours.
