Potterycrafts Front Loading Kiln Auto Damper and Heatlock

Description

The damper is pre-set to close when the kiln temperature reaches 550C, it opens again when the kiln cools down to 250C. 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.The Heatlock keeps the kiln door locked until the kiln has cooled to a safe temperature preventing damageto kilndoor 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 60C in the heating cycleand tounlock at 55C on cooling. A warning light indicates when the door is locked, when the light goes out it is safe toopen 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 55C.
