The particularly easy-to-use controller reliably regulates your firing programs. Our top loaders are not simply kilns, they are a reliable partner for your everyday pottery work and support you in realizing your creative ideas.
Insulation
Our top loaders are equipped with energy-efficient refractory insulation inside the chamber and microporous rear insulation that allows you to reach a top temperature of 1320 °C (2408 °F) with minimum energy consumption.
- Three layers of high-quality 15 mm microporous rear insulation for top loaders up to 60 liters to ensure that you reach your firing temperature reliably
- Two layers of high-quality 20 mm microporous rear insulation for top loaders from 80 liters for a well-balanced ratio between energy-saving heating and shorter cooling times for the kiln
Controller
- Controller with touch operation B500 (5 programs with each 4 segments)
Standard equipment
- Exclusive use of insulation materials without categorization according to EC Regulation No 1272/2008 (CLP). This explicitly means that alumino silicate wool, also known as “refractory ceramic fiber” (RCF), which is classified and possibly carcinogenic, is not used.
- NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
- Freeware NTGraph for evaluation and documentation of firings using ExcelTM for WindowsTM on the PC
- Freeware NTEdit for convenient program input via ExcelTM for WindowsTM on the PC
- Optimized insulation construction for a perfect balance between the best possible energy consumption and short cycle times
- Controller can be switched to “Solar Mode” to use electricity from PV systems with and without battery
- MyNabertherm App for online monitoring of the firing on mobile devices for free download
- Defined application within the constraints of the operating instructions
Treat yourself to something special for your hand-crafted works of art!
“Each time I open the kiln, I’m just as excited as I was after the first firing.”
