Hoshizaki KM-520MWJ Description
In Ideal conditions, the Hoshizaki KM-520MWJ ice machine head produces 474 pounds of crescent-cube ice per day. It is a water-cooled unit, and its self-contained condenser operates with R404A refrigerant. To reduce the buildup of bacteria in the machine, it's protected by H-Guard Plus antimicrobial, and it self-cleans in just an hour with Clean Assist. Because the components of this unit snap in and out, they can be removed for cleaning.
The Hoshizaki KM-520MWJ crescent-cube ice machine head has self-diagnostics that automatically adjust the unit to a changing environment. If something goes wrong, the EverCheck™ alert system tells users that maintenance is needed. Its evaporator is made of stainless steel to resist corrosion, and the finish is also stainless steel to provide durability.
Note: This unit must be paired with an ice maker bin or ice dispenser.
