Energy Recovery Filter Hood System   Publish Date: 9/1/2014

Energy Recovery Filter Hood System
The Energy Recovery Filter Hood System
(models GTEW, GTDW) utilizes heat exchangers in the hood filters to capture waste heat from the exhaust airstream.
A control panel with a pump redirects a portion of the incoming kitchen water supply to the filters (2-3.5 gpm) to pre-heat the incoming water, which helps reduce overall water heating costs. The cooler temperature of the filters condenses grease, which reduces the number of hood and duct cleanings over the life of the system.
