The 277 Rack/Hr High Temp Conveyor Dishwasher w/ Prewash utilizes Champion's two-tank wash system plus a 36-inch wide heavy-duty prewash module to handle even the dirtiest dishes that you can send its way. Champion has designed this high-temp conveyor dishwasher to not only provide you with an intense cleaning for your dishes, but to also conserve water and electricity. Such efficiencies as the Energy Sentinel, which is an idle pump shut-off, and the Never leak drain closure which uses a ball valve, have helped the Champion 100 HDPW earn its ENERGY STAR rating. The conveyor dishwasher features a top mounted control cabinet. In addition, Champion has designed an anti-jam conveyor drive system so you can wash up to 277 dish racks without worrying. Plus, the conveyor's vertical opening can accommodate items as large as an 18" x 26" sheet pan, increasing the variety of dishes that you can put through the unit. Note that this model is available standard with 208 Volt electrical, but there is also an optional 240 volt electrical model.
