Laboratory Chamber Furnace - CWF

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.

Standard features

• 1100°C, 1200°C or 1300°C maximum operating temperature
• 5, 13, 23, 36 or 65 litre chamber volumes
• Carbolite Gero 301 controller, with single ramp to set-point & process timer (CWF & CWF-B)
• 3216CC controller, with single ramp to set-point & process timer 
• Vertical lift door keeps heated surface away from the user
• Soft closing door on 5, 13, 21 & 23 litre models
• Delayed start / process timer function as standard
• Hard wearing alumina element carrier, furnace entrance and hearth
• Energy efficient low thermal mass insulation
• Free radiating wire wound elements for optimum uniformity
• Easy access to elements & controls simplifies maintenance & servicing
• CWF-B: Enhanced airflow from tall chimney & door vents for full combustion
• A range of sophisticated digital controllers, multisegment programmers and data loggers with digital communication options is available - more information about controllers
• Over-temperature protection (recommended to protect valuable contents & for unattended operation)

Options (specify these at time of order)

• A range of metallic retorts to work with modified atmospheres up to 1150°C
• Bespoke specifications are available for AMS2750F (Nadcap) compliant applications

Airflow in CWF-B

1. Air inlets through the door plug
2. Airflow through the chamber promotes burning of the samples
3. Chimney pulls air through the chamber
