THIS R-500-1240P ELECTRICAL PROGRAMMABLE KILN 160C/L CHAMBER WITH A 32-SEGMENT PROGRAMMABLE TEMPERATURE/TIME CONTROLLER AND 160 CUBIC LITER SPACIOUS CHAMBER IS ESPECIALLY DESIGNED FOR WORKING WITH MANY TYPES OF MATERIALS WITH FIRING POINT BELOW 1240 C (2264 F). FOR YOUR SAFETY THIS KILN HAS A SECURE MECHANISM THAT WILL DISCONNECT THE KILN'S POWER SUPPLY FROM ITS HEATING ELEMENT/S IF DOOR OF THE KILN IS OPEN OR CLOSED NOT PROPERLY. 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 PROGRAMMABLE CONTROLLER ON FLUCTUATIONS OF ELECTRICITY THAT IS VERY IMPORTANT OPTION FOR MOST CERAMIC, GLAZING AND POTTERY FIRING PROCESSES.Technical specification:- Brand name: Technical Supermarket (London);- Model: R500P-1240;- 230 Vac +/-10%, no plug - should be connected directly to 32 A circuit breaker;- 5500 Watt;- Maximum working temperature - 1240 C (2264 F);- Kiln dimensions in MM (inch): H700 x W700 x L750 (28" x 28" x 30");- Estimated heating time to 1240 C - 240 minutes;- Chamber dimensions in MM (inch): H530 x W530 x L570 (21" x 21" x 23" and 27" Diagonal)- Continuously working time on 1240 C (2264 F): 15 minutes;- 32 time/temperature segments 2-line programmable temperature controller that will allows you automatically reach, hold (soak) and change up to 32 temperature/time points;- Safety switch mechanism for disconnecting heating elements from a power supply if door is open or closed not properly;- Digital over/low-temperature regulation secure system;- Smoothing circuit (controller's stability work) digital guard;- Industrial graded K-thermocouple on right wall of the kiln;- Calibrated on five points.
