The Ice-O-Matic CIM0320HA ice machine produces up to 313 pounds of Half sized Cube ice every 24 hours (under optimal temperature conditions of 70 degrees Fahrenheit air and 50 degrees Fahrenheit water). The modular cuber head requires a 115 volt, 60 Hz, 1-Phase power supply. The Ice-O-Matic CIM0320HA cuber head is only 22 inches wide and should be mounted on an appropriately sized ice storage bin (sold separately) such as an Ice-O-Matic 22 inch storage bin. If placed on a 30 inch wide or wider bin, the cuber head will require a bin adapter plate. The Ice-O-Matic CIM0320HA has an air-cooled condenser and therefore requires air vents for intake and exhaust. The dual exhaust feature is designed to discharge hot air from both the side and top of the unit. This allows more options for installation location and reduces the potential for obstructed exhaust. The model's space-saving 22 inch wide design works well where there is limited left-to-right wall space available. With the 313 pounds of ice produced by the CIM0320HA daily, you should have a steady supply of half cube ice. Ice-O-Matic's Half Cube measures 3/8 inches by 7/8 inches by 7/8 inches and is ideal for filling beverage glasses. Producing the Half Cube at a rate of just over 13 pounds per hour, the Ice-O-Matic CIM0320HA is a good choice for a small to mid-sized business with moderate daily ice requirements. Ice-O-Matic has incorporated its PURE ICE technology into all ice making surfaces, providing built-in antimicrobial protection for the unit. Note that the Ice-O-Matic CIM0320HA does have some purge water that needs to be drained after each ice making cycle, so the location should have either a floor drain or an external drain pump (sold separately).
