Robust, semi-industrial front loading kilns ideal for professional studios, colleges and industrial applications where a larger capacity is required. Spiral wound elements are supported on tubes so heat from all around the element is exposed to the kiln chamber giving highly efficient use of energy. There are elements in the two side walls and floor as standard.
Constructed from low thermal mass insulation brick with two high grade backup insulation boards, the roof is a traditional curved arch construction again with two layers of backup insulation, enclosed within a 2mm zintec steel powder coated frame.
Graded Kanthal A1 Heating Elements are supported on ceramic tubes, positioned in the floor and two side walls.
Dual contactors provide security against over-fires, when used in conjunction with Potterycrafts Kiln controllers.
Block construction flat arched roof for greater strength and durability .

Kiln is made to order, delivery is approx 4-6 weeks (this will be confirmed when ordering)
CERAcontrol is the latest development in a long series of controllers, they incorporate new software giving improved efficiency and ease of programming together with up to date safety and diagnostic features.
CERA-5+ has 5 programs each with delay start, 5 heating/cooling ramps, soak, cut off and program pause.
This controller gives the benefit multiple heating and cooling ramps for pottery firing where usually two programs are used, having five ramps allows for several heating and/or cooling phases in the program.
CERA-10 has 10 programs each with 10 segments. Delay start and program pause. Each segment has a heating/cooling ramp, a target temperature and a soak. This controller is ideal for firings where a range of programs are frequently used.
It can be used for any firing requiring close control over multiple heating and cooling ramps such as macro crystalglazes and for glass slumping and fusing.
The Heatlock keeps the kiln door locked until the kiln has cooled to a safe temperature preventing damage to kiln door and eliminating risk of burning. The lock is discretely positioned adjacent to the interlock key under the door of our front loading kilns; it is operated by a small controller pre-set to lock at 60°C in the heating cycle and to unlock at 55°C on cooling. A warning light indicates when the door is locked, when the light goes out it is safe to open the kiln. The HeatLock is failsafe, if the power is turned off it remains locked, the door can only be opened when powered up and the temperature has dropped to 55°C.
The damper is pre-set to close when the kiln temperature reaches 550°C, it opens again when the kiln cools down to 200°C. There is no need to set the opening and closing temperature and no complicated controller as the temperatures are factory pre-set. The auto-damper eliminates the need to come back to the kiln during firing and removes the risk of the flue remaining open throughout the firing creating a potential hazard.
