Hoshizaki KM-660MWJ Description
The Hoshizaki KM-660MWJ crescent cube ice machine head is water cooled, so it resists hot ambient temperatures more effectively than an air-cooled system. It can produce 669 pounds of crescent ice each day and features a factory-installed ultrasonic bin control that automatically stops the production of ice when the bin is full. Because of its narrow profile, this ice machine head doesn't take up much space; it's a good size for smaller operations, such as corner stores and food courts.
The Hoshizaki KM-660MWJ ice machine head is built to streamline cleaning and maintenance of the machine, reducing operator labor and prolonging the life of the unit. Self-diagnostic features optimize production, while an EverCheck™ system monitors performance and alerts operators if issues arise. The simple design of the machine has less parts than previous models and features a snap-in construction that enables users to clean it in just one hour—encouraging daily cleaning.
Note: This unit must be paired with an ice maker bin or ice dispenser.
