TROY, OHIO—Hobart’s new patent-pending Energy Star qualified AM Select Ventless warewasher not only cleans and sanitizes dishware and heavily soiled pots and pans, but it also can save more than $5,000 in energy recovery, reduced HVAC use and the elimination of a vent hood and fan installation.

Using only .74 gallons of water per rack, the new AM Select is the first ventless door-type warewasher featuring energy recovery. Operators can save up to $792 per year in energy recovery (based on 200 cycles/day, 360 days per year at an energy cost of $0.011—or 1.1 cent—per cycle). Additionally, the elimination of the vent hood and subsequent makeup air into the kitchen reduces HVAC use, saving on average $776 per year in utility costs. Without the need for a vent hood and fan, the savings on equipment and installation costs is approximately $3,500. Previously, high temperature door-type warewashers required a vent for the steam or water vapor emitted when the door is opened.

“Since there is no vent on Hobart’s AM Select Ventless, there is no need for ductwork for the ventilation hood, making it easy to install the units where it is most convenient and productive for the operation of a kitchen,” said Carrie Hoff, product line manager of Hobart Warewash. “Additionally, the energy recovery system harnesses the existing heat and steam generated by the machine that otherwise would have escaped when the door was opened.”

The AM Select Ventless has a unique energy recovery condensing cycle that captures water vapor (more commonly referred to as steam) from the wash cycle and condenses it to heat the incoming cold water. A fan circulates the air from the chamber—filled with water vapor—across the fins of the heat exchanger coils filled with cold water at 50 degrees Fahrenheit to 80 degrees Fahrenheit. The difference in temperatures causes the water vapor to condense and preheats the inlet water used for final rinsing. The preheated water temperature reaches up to 140 degrees Fahrenheit, which reduces the amount of energy needed to reach the required 180 degree Fahrenheit rinse-water temperature. The energy recovery system allows operation using a cold water supply and uses the hot water line only for the initial fill. After the completion of the 30-second condensing cycle, an indicator light signals the machine is ready for unloading, and then the process starts over.

The new AM Select warewasher is not only ventless, but it is also like having two machines in one—one for pots and pans and one for dishware. Hobart’s AM Select Ventless achieves the stringent NSF guidelines for utensil washing, which means that pots and pans can be washed automatically instead of being scrubbed by hand. Less time spent soaking, scraping and scrubbing by employees means less turnover and more money to the bottom line. With adjustable cycle times of one, two, four and six minutes plus condensing cycle, the operator can wash anything from delicate glassware to soiled utensils.

The AM Select Ventless Series includes standard height, tall and front-loading models.
