Gas-heated chamber kiln for ceramic firing, with a front door that facilitates loading and handling. Professional quality.
Some firing processes or connecting conditions requires a gas-fired chamber kiln. Fast heating and very good firing results are strong reasons for using such equipment.
Equipped with powerful gas burners the chamber kilns NB 150 - NB 600 are suitable for creative applications. An automatic temperature regulation is included in the basic model. The controller starts controlling after the burner has been manually ignited by automatic swithcing the burner between high and low loads. The burners have been optimized to allow relatively precise control from 300ºC. Despite this, we still recommend drying the charge completely to avoid waste caused by rapid heating up in the lower temperature range. At the end of the program, the burners are automatically shut off.
