Carbolite Gero - Laboratory Chamber Furnace

The ELF laboratory furnaces comprise three bench-mounted models designed for light duty and general use up to 1100°C.

They have a simple drop-down door and a top-mounted ceramic chimney. The combination of low thermal mass insulation and free radiating wire elements embedded in the chamber sides provide efficient heating.

Key features

• 1100°C maximum operating temperature
• Carbolite Gero 301 controller with single ramp to setpoint and process timer
• 6, 14 or 23-liter chamber volumes
• Dropdown door with an air gap to minimize external temperature
• Delayed start / process timer function as standard

• Hard ceramic hearth fitted as standard
• Ventilated via the top-mounted ceramic chimney

Options

• Over-temperature protection (recommended to protect valuable contents & for unattended operation)

The CWF range of general-purpose laboratory chamber furnaces is bench mounted. Models are available in five sizes with a maximum operating temperature up to 1300°C. 

The airflow in the CWF-B furnaces is enhanced by the addition of air inlet holes in the door and a tall chimney which rapidly removes the fumes from the furnace.

• Hard-wearing hearth

Options

• A range of sophisticated digital controllers, multi-segment programmers and data loggers is available. These can be fitted with RS232, RS485 or Ethernet communications
• Over-temperature protection (recommended to protect valuable contents and for unattended operation)

These top loading chamber furnaces are particularly suited for applications involving tall crucibles and heavy components. Heating elements in all four walls minimize the risk of damage from spills and ensures good temperature uniformity. The smaller two furnaces may be bench mounted, but the best access is provided when these furnaces are located on the floor.

Key features

• Vented top opening door
• Angled control panel, protected but clearly visible
• Thermocouple protected by ceramic sheath

Options

• A range of sophisticated digital controllers, multisegment programmers and data loggers is available. These can be fitted with RS232, RS485 or Ethernet communications 
• Over-temperature protection (recommended to protect valuable contents & for unattended operation)

The RHF range of silicon carbide heated high-temperature chamber furnaces comprise four chamber sizes, each available with three maximum operating temperatures of 1400°C, 1500°C and 1600°C. Robust construction and high-quality elements provide rapid heating rates (typically reaching 1400°C in under 40 minutes) and long reliable working life.
