The CMA Dishmachines EST-AH-EXT Door-Type Dishwasher
The CMA Dishmachines EST-AH-EXT is a low temperature, chemical sanitizing door type dishwasher in a straight-thru configuration, built for restaurants and cafeterias that run racks in one line from the soiled table through the machine to the clean table. It washes, rinses, and sanitizes a standard 20" x 20" rack every 90 seconds, and the extended-height chamber gives you a full 20-1/2" of door clearance for sheet pans, mixing bowls, and tall stockpots that get turned away at the door of a standard-height machine.
40 Racks per Hour on 1.09 Gallons per Cycle
Rated at 40 racks and 160 covers per hour, the EST-AH-EXT keeps pace with a busy dinner service while using just 1.09 gallons of water per cycle, which works out to 43.6 gallons per hour at full tilt. Less water in means less water to heat, treat, and dose with chemicals, so the savings compound on every rack. A 1 HP motor drives the 52 GPM pump through upper and lower stainless steel wash arms with enough force to strip dried marinara off plates that sat through the rush.
Chemical Sanitizing Without Booster or Tank Heaters
Because sanitizing happens chemically rather than with scalding rinse water, this machine needs only a 120°F water supply, with 140°F recommended, and it runs on a standard 115 V, 16 amp circuit. There are no booster or tank heaters on board, so it produces no steam cloud when the doors open and your dish pit stays cooler. The sanitizing system delivers instant sanitation while eliminating the chlorine damage that shortens the life of many low temp machines.
Built-In Chemical Pumps with Deliming System
Top mounted controls house built-in chemical pumps that meter detergent, rinse aid, and sanitizer automatically, so a closing crew cannot under-dose a load to stretch supplies. An integrated deliming system fights hard-water scale before it coats the wash arms, and auto start/stop triggers the cycle the moment the doors close. The power drain empties the machine quickly without a noisy solenoid or an external sump, which also frees up space under the unit.
Stainless Steel Construction with Poly Pro Scrap Accumulator
The cabinet, wash arms, scrap tray, and even the pump impeller are stainless steel, and a self-cleaning pump screen heads off the clogs that generate service calls. A built-in Poly Pro scrap accumulator and integrated stainless steel scrap tray trap food soil before it reaches the drain, while the airgap fill system and strainer-equipped water inlet protect the water valve from debris. Two dishracks come standard, and the machine converts from straight-thru to corner operation if you remodel the dishroom later.
