Commercial Food Services
Dishwashers | Food Steamers | Ice-Makers | Pre-Rinse Spray Valves (PRSVs)
Commercial dishwashers and pre-rinse spray valves (PRSVs) in the typical restaurant dishroom together represent the largest consumer of water in such establishments. While much has been done by water providers to reduce water use through efficient PRSVs, the efficiencies achieved by dishwasher manufacturers have been largely without the support of the water industry. Instead, since water and energy are linked within the commercial dishwasher, the demands for energy efficiency have resulted in manufacturers developing and marketing extremely water-efficient models. For example, in the late 1990s, NSF International (the listing agency for such machines) showed that the most efficient dishwashers used 1.2 gallons of water per (20-in by 20-in) rack. Today, machines are available at well below 1.0-gallons per rack.
