Halton Marine Introduces Intelligent Hood Ventilation

Halton Marine has introduced what it calls the first intelligent, responsive, and completely flexible demand controlled ventilation (DCV) system specifically designed for Halton hoodsin galleys and kitchens. In combination with the company’s capture-jet-technology it offers the lowest levels of energy consumption and provides complete comfort for users, according to Halton.

Called MARVEL, the DCV system is able to identify the current status of the cooking equipment (switched off, heating to cooking temperature, or cooking in progress), and adjusts the exhaust flow rate to match the condition, and can also do this independently, hood by hood, Halton stated. So if only one cooking range is operating in the galley, the flow rate for that hood or zone will be automatically adjusted. The other hoods or zones will continue operation at a low flow rate.

MARVEL is capable of continuously regulating the flow rate achieved with extraction fans, but also, and most important, according to Halton, by pressure. By operating at a variable pressure and flow rate, this system fine-tunes the equipment to a defined area and requirements, with power consumption kept to a minimum. The supply fans are also controlled, enabling an air flow balance in the kitchen or galley.

The system is flexible and can be reprogrammed at any time in response to changes in kitchen or galley layout.

With Halton’s capture-jet-technology reducing the exhaust airflow rates by 30 to 40 percent, compared to traditional single-flow hoods, and MARVEL reducing the airflow by another 44 percent, the combination can provide a total exhaust airflow reduction of 63.6 percent compared to traditional systems.
