Greenheck's new Model GRRS fire-ready hood functions as a standard ventilation range hood with the added capacity to suppress stove-top fires, addressing the challenge of protecting residential-style appliances used in commercial settings.

Designed for use over a standard 30 or 36-inch residential range, Model GRRS incorporates a UL300A Listed self-contained, commercial-style automatic fire suppression system. The hood's exhaust fan can be either manually operated with the face-mounted dial or automatically operated based on the hood temperature that is monitored by an onboard controller. Model GRRS is ideal for applications such as healthcare facilities where meals are prepared for 30 or fewer persons.
