The Hoshizaki AM-50BAJ undercounter ice maker can produce as much as 51 pounds of top hat ice in 24 hours. This amount depends on ambient air temperature and incoming water temperature—the lower they are, the more ice the machine makes. To create ice cubes, its air-cooled condenser uses R134A refrigerant. Airflow is provided in and out of the front of the unit for consistent operation. Because this self-contained unit features an air-cooled condenser and few moving parts, it can run for a long time.
