Abstract
An energy saving controller for kitchen exhaust systems is disclosed in which the exhaust fan speed is varied in proportion to the level of cooking by-product seeking to escape from a flow path within the exhaust hood. The exhaust fan speed may also be varied in relation to the heat load of the cooking units as indicated by temperature above the units or energy consumed thereby. Further, where make-up air is provided, the speed of the make-up air fan may be similarly varied.
