Instead of installing a large number of individual exhaust ducts for each appliance, or a fan that operates at full speed 24/7, ENERVEX’s Modulating Building Exhaust System (MBESx) senses when appliances are running and modulates with the load. It assures proper exhaust rates at any time no matter the demand and can reduce the exhaust rate of conditioned air by up to 60-70%. This demand-controlled, variable speed ventilation system is designed for multi-story buildings with multiple kitchen hoods, bathrooms or clothes dryers on multiple floors.
