An 85% reduction in cooker hood electricity costs is being achieved at Pizza Hut’s Watford Dome branch following the installation of a 1.5 kW and a 3 kW ABB drive on the air extraction cooker hood system.
The new system, installed by energy saving ventilation control system specialist, Food Industry Technical (FIT), controls air supply and extraction by monitoring carbon dioxide (CO2) and temperature in the kitchen.
The system improves energy efficiency in the kitchen by matching fan speeds to the needs of the application. For added safety the system accurately measures CO2 levels within the kitchen space and initiates air extraction when levels increase. A CO2 alarm was also fitted to further ensure staff safety in the kitchen area.
