THIS IS VERY USEFUL 1200 C ELECTRICAL MUFFLE KILN WITH WI-FI PROGRAMMABLE TEMPERATURE/TIME CONTROLLER AND 38 CUBIC LITERS SPACIOUS CHAMBER THAT IS ESPECIALLY DESIGNED FOR WORKING WITH ALL TYPES OF MATERIALS ON TEMPERATURES BELOW 1200 C (2192 F). FOR YOUR SAFETY THIS KILN HAVE A SECURE MECHANISM THAT WILL DISCONNECT KILN'S POWER SUPPLY FROM ITS HEATING ELEMENT/S IF DOOR OF THE 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 PROFESSIONAL FIRING PROCESSES.Technical specification:- Brand name: Technical Supermarket;- Manufacturer: Treatment of Surfaces LTD (London);- Model: WFR-310P;- CE marked, ISO-9001-2008;- Single phase, 230V+/-10%;- Supplied with no plug: should be connected directly to 32 A circuit breaker;- 6300 Watt;- No asbestos;- Maximum working temperature - 1200 C (2192 F);- Heating time to top temperature - 240 minutes.- Continuously working time on top temperature = 20 mins.
