Greenheck’s Optics-Driven Hood Controls Enhance Kitchen Ventilation
May, 2025
Greenheck now offers factory-installed optics sensors as an enhanced option for its kitchen hoods. Model GKC kitchen ventilation controls feature hood-mounted temperature sensors as standard, which respond five times faster than duct-mounted temperature sensors to modulate airflow. In addition, optics sensors can detect smoke and steam within seconds to trigger the exhaust fans. They can be included in an optional variable volume system capable of turning down fan speeds by up to 50%. The resulting energy savings meet ASHRAE 90.1, IECC 2024, and California Title 24 energy standards. 
Model GKC controls have an easy-to-use color touchscreen display for precise control of fans, make-up air, and lights. This touchscreen can now be added to each hood section, making individual hood light and fan zone control easier. Greenheck’s full line of kitchen ventilation equipment includes exhaust hoods and fans, make-up air, utility distribution systems, fire suppression systems, dedicated outdoor air systems (DOAS), and pollution control units.
