The Carbolite Gero CWF 12/23 is a high-performance, bench-mounted laboratory chamber furnace engineered for general-purpose thermal processing, advanced ashing, high-temperature calcination, and materials testing. Providing an optimal chamber volume of 23 litres and an extended maximum operating temperature of 1200 °C, this muffle furnace is globally recognized for its heavy-duty reliability and outstanding thermal stability. The heating architecture pairs free-radiating wire-wound elements with energy-efficient, low thermal mass insulation to guarantee deep thermal penetration, excellent response times, and minimized energy consumption.
User safety and industrial ergonomics are central to the CWF 12/23 design. It features a vertical lift door mechanism that ensures the radiant, white-hot inner insulation face is always directed away from the operator during loading and sample extraction. To safeguard the structural core against mechanical degradation and friction, the furnace entrance, structural hearth, and element carriers are manufactured from heavy-wearing alumina ceramics. Thermal cycles are precisely governed by the digital Carbolite Gero 301 PID controller, offering smooth single-ramp control, automated delayed start, and integrated digital process timing.
Vertical Lift Door with Soft-Close: Upward-opening door architecture shields the technician from direct radiant heat, featuring an integrated soft-close dampening system to eliminate sarsıntı.
Optimized Radiant Uniformity: Free-radiating wire-wound heating elements deliver highly effective, linear, and balanced heat distribution throughout the internal chamber.
Heavy-Wearing Alumina Ceramics: Hard-wearing alumina element carriers, furnace entrance, and base hearth resist mechanical abrasion and sample outgassing contamination.
Energy-Efficient Thermal Shielding: Low thermal mass insulation ensures quick heat-up rates (reaching max temperature in 45 minutes) while maintaining low outer casing temperatures.
Intuitive Digital Automation: Outfitted with the Carbolite Gero 301 PID controller as standard, supporting single-ramp heating profiles, digital process timing, and a delayed start function.
Service-Friendly Layout: Direct access to internal electronic components and heating element sub-assemblies simplifies routine maintenance, technical service, and calibration processes.
