Commercial Dishwashers

Commercial dishwashers are found in almost all establishments that use non-disposable dishes, glassware, and utensils; such as restaurants, bars, schools, hospitals, nursing homes, churches, and institutional cafeterias.
Commercial dishwashers can clean and sanitize a large quantity of kitchenware in a short amount of time by utilizing hot water, soap, rinse chemicals, and significant amounts of energy. Size requirements for commercial dishwashing machines can be calculated by estimating the number of individuals served by the food service establishment. This information is a key determinant of the type of dishwasher that is most suited for a facility.
