Demand Control Kitchen Ventilation (DCKV) is a system that incorporates sensors that monitor the state of the CKV hood, CKV hood duct, and/or cooking equipment. The monitors provide information on the state of the CKV components and send information to a control panel that varies the amount of power that is supplied to the exhaust and make up air fans. A DCKV system will reduce the amount of energy the CKV System is using by turning down the fan power during off peak cycles.
