Intelligent and compliant hood washing system management

Valmet Hood Washing System Control

Valmet DNAe Hood Washing System Concept upgrades traditional on-site manual operation systems by adding preset cyclic hood cleaning, adaptive detergent dosing, interlocked fan protection and residual wastewater drainage management functions.

Galley exhaust hood

Ship galley exhaust hood accumulates grease, food sediment and oil mist during vessel navigation, bringing major galley fire risks and ventilation efficiency loss. Due to mandatory maritime fire prevention and onboard hygiene requirements, Valmet’s Hood Washing System Concept delivers unified process control for galley hood cleaning units. Custom integration with onboard detergent dosing units and fire safety interlock systems is available according to third-party equipment vendor specifications. 

Waste washing water

Hood washing wastewater contains grease, food residue and cleaning chemicals, classified as oily galley wastewater restricted by MARPOL regulations. Therefore, linked collection, classified transfer and standardized discharge of hood washing water is critical to meet global marine emission standards.
