Due to their good price-performance ratio, the Nabertherm chamber kilns heated from three sides are suitable for use in schools, kindergartens or occupational therapy. The heating elements are protected in grooves. These kilns are ideal for working temperatures between 900 °C and 1250 °C. For an intensive, professional use, we recommend our five-side heated chamber kilns. . The dual-shell, back-ventilated housing keeps the housing temperature low. A semi-automatic air inlet flap is included with standard scope of delivery. After the drying phase in the heating program, the flap closes automatically at a chosen temperature. No base flap has to be closed manually. The controller can be removed from the door bracket for convenient operation.
