Some firing processes require a gas-heated chamber kiln. Fast heating times and unique firing results are strong reasons for using such equipment. Equipped with powerful gas burners the chamber kilns NB 300 - NB 600 are suitable for many creative applications. Temperature regulation included in the basic model The controller starts controlling after the burner has been manually ignited by automatically switching the burner between high and low loads. The burners have been optimized to allow relatively precise control from 300 °C. Despite this, we still recommend drying the charge completely to avoid waste caused by rapid warming in the lower temperature range. At the end of the program, the burners are automatically shut off.
