Top 3 Dishwasher Innovations for K-12 Foodservice Programs

November 19, 2019 by Hobart


When it’s time to purchase new commercial dishwashers for your school’s foodservice operation, try not to become overwhelmed by all the choices. Today’s commercial dishmachines come with technological advances designed to create efficiency for your dishroom and provide financial benefits as well as improved sustainability. Consider these commercial dishwasher innovations and decide which options are best for you.

Ventless Energy Recovery

Ventless_1This feature is available on every size of high-temperature commercial dishwasher and can significantly decrease your operation’s utility and installation costs. Here’s what you need to know: Ventless energy recovery technology condenses steam and recycles heat from the wash chamber to bring incoming cold water temperatures up to 110 degrees, so the machine doesn’t have to work as hard to reach its required 180 degrees for sanitization. The result? Less energy is needed to operate the machine and less steam is emitted into the dishroom, making working conditions more comfortable for your employees. And, because the steam is condensed and removed from the chamber, a vent hood or direct venting are not required - saving over $3,500 on new installations.

Drain Water Energy Recovery, or DWeR

DWeR_1Look for this technology when considering a conveyor-type dishmachine. For instance, the Hobart CleN conveyor type dishwasher with DWeR reduces water usage by 90 percent. How does it work? The Advansys DWeR process captures heat energy from the drain water and uses it to increase the temperature of incoming cold water to 110 degrees, so the booster heater has less work to do to reach the required 180 degrees for proper sanitization. The hot drain water is cooled below 140 degrees, which also eliminates the need for added water for drain tempering. DWeR technology makes smart use of water and energy that would otherwise—you guessed it—just go down the drain.

Automatic Soil Removal, or ASR

ASR_2While money-saving innovations are important to any K-12 foodservice environment, dishmachine features that save operators time on the front end are also in demand. If your team is spending a lot of time pre-rinsing and pre-scrapping before the ware items even make it into the machine, this technology will reduce that effort significantly. ASR pumps food soils out of the wash tank, so wash water stays cleaner longer. You can do less pre-scrapping and still have fewer wash water changes. It also minimizes the chance of rewashing, not to mention improving overall results. So, when you’re considering which replacement dishwasher to purchase, look for the ASR feature. Fewer tank fills will result in water conservation as well as energy savings.

ENERGY STAR® Qualification

POY_SustainedExcellence_2019lg_0-1To further promote your operation’s sustainability efforts, look for the ENERGY STAR® logo. Why is this important? According to, commercial dishwashers that are ENERGY STAR certified are, on average, 40 percent more water and energy efficient than regular models. All Hobart CleN conveyor-type and Advansys door-type commercial dishwashers are ENERGY STAR certified. Remember that your ENERGY STAR equipment purchase may also qualify for rebates. Eligible commercial dishmachines can have incentives as high as $2,700. Check the ENERGY STAR website for more details.

Operator Ergonomics & Cleaning

Commercial dishwasher innovations may be equipment-based but they can also directly benefit the operator. Since staffing is always a big part of managing a foodservice operation, think about purchasing a dishmachine that contributes to operator satisfaction. Look for easy-to-read controls, ergonomically designed handles and features that make cleaning a breeze.

Choosing a replacement dishwasher for your K-12 kitchen is simple when you know the latest innovations and which ones are the priorities for your foodservice program. Use this guide when deciding which model to purchase and remember a few quick takeaways: The Hobart Advansys Ventless models can provide big cost savings—as much as $5,000 in the first year and up to $1,500 every year after. Plus, ENERGY STAR® certification helps ensure noticeable decreases in utility bills, which helps the bottom line AND sustainability initiatives.
