Pennram - Secondary Chamber

Air introduction to the secondary chamber is fully modulated by variable speed controls of the fan motor or by modulation of an air control damper. The control of air delivery to the secondary chamber is cycled with each firedoor opening to the primary chamber and is controlled by the secondary chamber temperature and/or exhaust levels.

Similar to the primary chamber, the Pennram secondary chamber is also provided with heavier refractory and insulation liner than others for better performance and longer service life.
