These CWF furnaces feature the quality components and workmanship you expect from a Carbolite box furnace. They include hard ceramic hearths which provide excellent resistance to wear and spillage. Dense refractory around their chamber entrances resist abrasion and wear, and their chambers are vented for expulsion of process exhaust. Every unit is built for dependability and long-life performance.

Like all of our box furnaces, our CWF General Purpose Box Furnaces are designed with operator safety in mind. Their vertical-lift door design keeps hot door insulation away from the operator. Double shell construction ensures low outer case temperatures, and their positive break door safety switches cut power to the heating elements when the door is opened.

Carbolite’s 1100°C, 1200°C and 1300°C General Purpose Box Furnaces deliver world-class performance, quality, safety, and ease of use. See the chart below for further information and specifications, or contact us today for more details.
