The RWF rapid wire chamber furnaces are available in three chamber sizes with maximum operating temperatures of 1100 °C or 1200 °C. The free radiating wire elements in combination with low thermal mass insulation are designed to provide rapid thermal response within the chamber.
Standard features
- 1400°C, 1500°C or 1600°C maximum operating temperature
- Programmable EPC3016P1 controller
- 3, 8, 15 or 35 litre chamber volumes
- Vertical lift door keeps heated surface away from the user
- Soft closing door (3 & 8 litre models only) protects the thermal insulation
- Silicon carbide heating elements provide long life and are able to withstand the stresses of intermittent operation
- RHF 3 & 8 litre have a cast alumina hearth; RHF 15 & 35 have silicon carbide hearth
- Low thermal mass insulation for high energy efficiency
Options (specify these at time of order)
- 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)
- Heating element protection tiles

Cement Testing for Compliance
The compliance of cement with standards such as EN 197 / ASTM C 150 is a quality requirement. Quality assurance of the raw materials used in calcination and also during the clinker production is necessary. Carbolite Gero offers different furnaces that help to guarantee quality requirements are met during the production cycle.
