Working - Air passes over hot heat exchanger (tube & shell type) & gets heated. Hot air is supplied thro’ duct & flow can be adjusted by adjusting dampers. Dampers are fitted in oven at bottom throughout the length sidewise. Hot air already supplied in oven, recalculates through’ suction duct to heater box. So the time required to heat-up re circulated air is less than heating fresh air.
