Large heavy-duty dish washers are available at Chef's Choice for all your commercial needs.  Commercial dish machines can wash a rack of dishes or a rack of 25 glasses in roughly a minute.  In the U.S., the NSF International sets the standards for wash and rinse time along with a minimum water temperature for chemical or hot water sanitizing methods.  There are many types of commercial dish washers including under counter, single tank, conveyor, flight type and carousel machines.  All dish washers sold by Chef's Choice are NSF approved.
