Oven Recirculation
Oven manufacturers size recirculation fans using the volume of the oven structure and a desired temperature gradient in the work area. The number of air changes per minute will result in the required airflow circulation for the fans. The burner is selected to heat this amount of air and the oven structure, plus the material to be baked or heat-treated. Designers must determine if they need to have single or multiple recirculation fans. Multiple fans allow for counter rotation of air currents which some designers feel gives a better temperature gradient. Batch ovens usually use smaller single fans and large, continuous-operation ovens usually use multiple fans. By using internal plenum chambers, fan wheels can be mounted in the oven ceiling or walls to circulate air throughout the oven. If the workspace for the oven includes considerable headroom, mounting the fans on top of the oven results in saving floor space. Mechanovent supplies fans and fan components to a wide variety of OEM oven manufacturers.
