5 Oven construction and operation
Ovens Series UNP and INP have natural ventilation.
In Series UFP, SFP and IFP ovens, air circulation is provided by a fan on the back wall of the chamber.
The incoming air (1) is warmed in a preheat chamber (2) in both convection and fan-circulation ovens. The
preheated air enters the chamber (4) through ventilation slots (3) in the chamber side wall. The fan (5) on
the chamber back wall produces a larger air throughput and a more intensive horizontal forced circulation
compared with natural convection. The air valve (6) on the back of the oven controls the rate of air intake
and discharge (air change) (7).
