How do you make an energy-efficient warewasher even more efficient? One way is to recommend equipment with built-in Energy Recovery systems, such as Hobart’s FT900 Flight-Type Warewasher. Energy Recovery systems reduce energy costs by 16 percent by using cold water for the final rinse cycle.

“Using cold water with temperatures as low as 55 degrees Fahrenheit or 13 degrees Celsius, foodservice operations can save $3,200 annually,” explains Allen Hasken, warewash development manager at Hobart. “By using a cold water supply, Energy Recovery systems provide an energy-saving option that pays for itself in approximately 15 months.”

Energy Recovery systems work by capturing escaping heat and steam from the exhaust air and using this energy to preheat the incoming cold-water supply before it enters the booster heater, where the water is brought to the final rinse-water temperature.

To address critical food safety and sanitation concerns, Hasken recommends Energy Recovery systems that monitor the incoming water temperature to the booster heater during the initial warm-up period. These systems can make adjustments to ensure the final rinse-water temperature meets the 180-degree-Fahrenheit requirements without a lengthy start-up period.
