Product Overview
The Fully Integrated Self-Cleaning Hood System helps keep your kitchen ventilation system clean with maximum grease extraction efficiency. The system is available with hot water wash integrated into GreaseMaster ’s premier canopy style GSN-2 and GSD-2 hood lines.
The hot water wash system automatically cleans the hood plenum after the day’s cooking is completed. Washing the hood plenum with surfactant (surface-active agent that reduces the surface tension between the grease and water allowing the water to dissolve the grease) while the hood is hot considerably increases cleaning effectiveness. The added riser sprayer also drastically reduces the need for grease duct and hood cleaning. Timing for both the surfactant and wash length is programmable to meet your specific needs.
