THIS IS A MOST USEFUL R-1100 C ELECTRIC MUFFLE KILN WITH STANDARD P.I.D. TEMPERATURE CONTROLLER AND 11.5 CUBIC LITER SPACIOUS CHAMBER THAT IS ESPECIALLY DESIGNED FOR WORKING WITH ALL TYPES OF MATERIALS ON TEMPERATURES UP TO 1100 C (2012 F). FOR YOUR SAFETY THIS KILN HAVE A SECURE MECHANISM THAT WILL DISCONNECT THIS KILN'S POWER SUPPLY FROM ITS HEATING ELEMENT/S IF DOOR OF THIS KILN IS OPEN OR CLOSED NOT PROPERLY. IT HAS ONE 16-MM HOLE WITH A STAINLESS STEEL SHUTTER ON THE DOOR TO SEE FIRING OBJECT/S DURING ALL FIRING PROCESS. THIS KILN HAS ALSO A DIGITAL, OVER/LOW-TEMPERATURE REGULATION SECURE SYSTEM TO HOLD SAME TEMPERATURE DURING THE WHOLE SOAKING PROCESS AND A SMOOTHING CIRCUIT DIGITAL GUARD FOR ACCURATE READING AND STABILITY WORK OF THE TEMPERATURE CONTROLLER ON FLUCTUATIONS OF ELECTRICITY THAT IS VERY IMPORTANT OPTION FOR MOST MATERIALS.Technical specification:- Brand name: Technical Supermarket;- Model: R-1100C;- CE, UKCA, FCC, CPSA, ISO:9001 certified;- 115 Vac or 230 Vac +/-10% with a standard EU, UK, US or AU electrical plug (on request);- Single phase, 10 A;- 2600 Watt;- No asbestos at all;- Maximum working temperature - 1100 C (2012 F);- Heating time to temperatures higher 1000 C - 80 minutes;- Continuously working time on temperatures higher 1000 C = 8 hours.
