Description The CH44 and CH66 models of Energy Star-qualified rack conveyor warewashers wash 219 racks per hour using 130 gallons of water per hour and .59 gallons per rack. Operators can reverse the CH44 components to change the direction of how the unit functions. The CH66 includes a 22-inch seamless prewash. New built-in diagnostics troubleshoot and solve issues quickly. Vent cowls capture and redirect hot air, providing both enhanced machine performance and decreased heat emissions.
