Full Description

This report was devised to share results from 20 field research projects completed by Fisher-Nickel Inc., along with operating characteristics and domestichot water (DHW) sizing information, for a wide array of facilities to understand the workings and impact of conveyor dishwashers. Models selected formonitoring ranged from the smallest rack conveyors to the largest flight-type conveyors. The results for all machines were normalized for water and energyuse per hour of rinse operation to provide a better comparison between models from different facilities. The normalized results demonstrated an averagesavings opportunity of 60% in water and energy use that could be achieved by replacing older conventional dishwashers with new efficient models. Theaverage conveyor monitored in this study used 920,000 gallons (3,482,579 L) of water, 113,000 kWh (406,800 MJ) of electricity and 10,700 therms(1,128,850 MJ) of natural gas per year. Based on Fisher-Nickel Inc.'s extensive lab and field research (Johnson et al. 2013), (Bell et al. 2012),(Karas and Fisher 2006), conveyor dishwashers are the single most combined water-and-energy intensive appliance operating in commercial kitchens.
