Large Grocery Store Kitchen Exhaust System Install

Chimney Works just completed the installation of a large kitchen exhaust system for a grocery store in Washington, DC. We used DuraSystems Model KEX which is a double wall 2-hour fire rated grease duct. The duct runs connected to various kitchen hoods such as a fryer hood, bagel kettle, main kitchen hood and pizza oven. The ducts ran through the grocery store and up to the roof where they connected to fans (installed by another contractor). DuraSystems can create custom square to round or round to square transitions to connect to various pieces of equipment like the fans and hoods we connected to on this job. Access doors are placed strategically throughout the duct runs to allow for easy duct cleaning.
