Single Zone vs. Multi-Zone

• 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.
