If you are looking for the kiln, which is capable of heating up evenly all your firing materials at the same time when, look no further, because our new R-1300C-ACS (Air circulation system Kiln) is the perfect match for your needs.This 1300C-ACS electric muffle kiln with a 32-segment standard controller and 11.5 L chamber. This kiln was especially designed for working with all, most popular materials such as: metals, ceramics, glazing, stones, enamels and others that should be heated up to temperatures up to 1300 c/2372 f. For your safety, this kiln has also a secure mechanism that will disconnect the kilns power supply from the heating elements if the door of the kiln is open or closed not properly. It also has one 16-mm hole with a stainless steel shutter on the door to see firing objects during firing process. It 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.WHY YOU MAY WANT TO BUY OUR PRODUCT (Air circulation system Kiln)We also designed and implemented an unique air circulation system on this kiln which will allow you to distribute the heat evenly inside the chamber and therefore the materials inside will be heating up evenly throughout the entire chamber. Due to increased air flow circulation, the required firing temperature can be reached in a shorter amount of time. Also, the heat being transferred more efficiently will significantly reduce the risk of overheating the heating element and consequently will extend its lifespan, which in return will make your kiln last longerTechnical specification: Brand name: Technical Supermarket; Model: R-1300C-ACS; 115Vac +/-10% or 230 Vac +/-10% with UK; EU or AU standard electrical plug on request; 2900 Watt. 50-60 Hz; Maximum working temperature 1300 C (2372 F); Kiln dimensions in MM (inch): H470 x W380 x L560 (18.1/2 x 15 x 22); New empty kiln estimated heating time to 1300 C 90 minutes; Chamber dimensions in MM (inch): H200 x W200 x L290 (8 x 8 x 11.1/2 and 14 Diagonal) Continuously working time on 1300 C (2372 F): 15 minutes; Continuously working time on temperatures below 1000 C (1832 F): 24 hours; P.I.D. standard temperature controller that will allow you to pre-set one single temperature, reach and hold it as long as you need before change it manually on different one or turn your kiln off; Ventilation hole on the door (with a stainless steel shutter);- Ajustable flow Air Circulation System 0.2-20 LPM; Safety switch mechanism for disconnecting heating elements from power supply if door is open or closed not properly; Position of three heating elements: right, left and top; Digital over/low-temperature regulation secure system; Smoothing circuit (controllers stability work) digital guard; Industrial graded K-thermocouple on right wall of the kiln; Calibrated.
