CMA Dishmachines EST-66 66 In. Conveyor Dishwasher, 249 Racks/Hour, 4-Stage Wash, High or Low Temp Sanitizing

The CMA Dishmachines EST-66 is a 66" conveyor dishwasher rated at 249 racks per hour that adds a second wash station to the wash sequence, giving heavily soiled ware more contact time than a shorter conveyor can. High volume operations like hospitals, universities, and banquet kitchens run it in either high temperature or low temperature chemical sanitizing mode, matching the machine to their chemical program and ventilation reality.

249 Racks per Hour at 0.46 Gallons per Rack

The rated capacity of 249 racks, or 996 covers, per hour rides on a 6.75 ft/min conveyor, letting the crew feed racks end to end instead of pausing for door cycles. Water use at the final rinse is only 0.46 gallons per rack, 114.54 gallons per hour flat out, so the extra wash capacity does not come with extra water cost. Automatic water control and auto fill hold tank levels, while auto start/stop idles the pumps whenever the chamber is empty.

Multi-Stage Wash Process with Power Rinse

Four stages work every rack across 66" of machine: a 2.5 gallon pre-wash tank knocks off loose soil, an 11.75 gallon wash tank scrubs, a 4.25 gallon power heated rinse follows, and a fresh water final rinse finishes, for 18.5 gallons of total tank capacity. That pre-wash stage is the difference between this machine and a 44" conveyor, since baked-on food gets loosened before the main wash instead of riding through it. Each tank feeds a 52 GPM pump, driven by a 1 HP wash pump and 1/3 HP rinse pump, with a 1/8 HP conveyor motor moving the line, while a 13 kW wash tank heater and 3 kW rinse tank heater, both chemical resistant industrial grade, hold temperature through continuous racks.

High Temperature or Low Temperature Sanitizing

In high temp mode the wash runs 150°F to 160°F, the pumped rinse holds 160°F, and the final rinse sanitizes at 180°F to 195°F. In low temp mode, chemical sanitizing lets wash, pumped rinse, and final rinse all run at 140°F to 150°F, easing exhaust and water heating loads. You choose between chemistry cost and energy cost based on your own utility rates and hood capacity.

Rack Saver Clutch and Automatic Soil Purging

A table limit switch and rack saver clutch system protect the machine, dishracks, and tables by stopping the drive before a jam turns into damage. The automatic soil purging system filters wash water and traps plate debris in an external stainless steel tray you can pull and rinse in seconds, keeping wash water cleaner deep into a banquet push. Curtains lift out for cleaning, the 19" opening takes larger wares and utensils, and the whole machine is stainless steel, with a 316 grade stainless steel chemical injection chamber at the point of highest chemical exposure. One open rack and one peg rack come with the machine, and you specify left or right rack travel when ordering.
