CWF furnaces


1100°C 1200°C 1300°C CWF Chamber Furnaces

These furnaces integrate the best traditional and modern materials to produce an outstanding combination of performance and reliability.

The unique concept for this furnace is the heating module - with one situated on either side of the chamber. Each heating module consists of a high quality alumina based hard wearing element carrier, housing a free radiating coiled wire element. With the use of graded wiring, the elements compensate for heat loss and optimise temperature uniformity within the chamber. The furnaces reach working temperature quickly and efficiently.

Hard wearing refractories around the chamber entrance and in the chamber base provide excellent resistance to everyday wear and tear, whilst secondary, low thermal mass insulation ensures maximum thermal efficiency.

Service is aided by the removable instrument panel and easy access to the element modules and thermocouple through the rear of the case.

Chamber sizes are 5, 13 and 23 litres with maximum temperatures of 1100°C, 1200°C and 1300°C.
