Single Zone Firing vs. Multi-Zone Firing

• Many kilns have one thermocouple to control all elements (single zone).
• In single-zone kilns, the elements are often graded in power output from top to bottom to adjust for temperature variation.
• In L&L's multi-zone kilns, there are multiple thermocouples to control the different elements in each section. 

Effects on Kiln Loading and Element Life

• With single-zone kilns, there is no way to adjust for varying load conditions in an unevenly loaded kiln.
• As graded elements age and change in power output (at varying rates because of their different designs) they lose accuracy.
• L&L's Dynamic Zone Control handles these conditions automatically. 

Dynamic Zone Control with the DynaTrol and Genesis

• The DynaTrol and Genesis feature Dynamic Zone Control.
• The control separately measures temperatures in the bottom, middle, and top of the kiln and automatically adjusts the heat output from top to bottom.
• Kiln temperatures are automatically evened out as a result.
