The Hobart AM15VL-6 is economically friendly in that its main feature is the ventless system that recovers heat from evaporated water, recycling fresh water and saving energy. Thus, this machine doesn't need to be installed under a vent hood. This model can wash up to 40 racks per hour while only using .74 gallons of water per rack for the final rinse. If needed, the upper and lower rinse arms are removable for cleaning, or if you need to insert bigger items for wash. The arms are also anti-clog designed. Along with a few other Hobart dishwashers, this machine also has a timed option for cycle choice 1-6 minutes. The system offers a 70°F rise Sense-A-Temp™ booster heater, eliminating the need for a chemical sanitizer. Another great feature is the convertible option to be straight through or corner installation. This unit meets NSF and UL standards, and is Energy Star qualified.
