Boost your savings with the optional Energy Recovery System available on our RackStar 66 Conveyor! The Energy Recovery System captures exhaust heat that is repurposed to heat the incoming cold water before it enters the booster heater.  Ground temperature water passes through the heat exchanger which uses this “free” heat to elevate the temperature of the water to 110 °F.  This process reduces overall energy consumption and saves thousands of dollars versus non-energy recovery models with higher water consumption.  Available in 44” and 66” (22” pre-wash added) models.
