Product Description

The Hoshizaki KM-520MWJ is a 22-inch water-cooled modular Crescent Cuber head producing 474 pounds of ice per 24 hours. It is the version to specify when the machine will sit in an enclosed or poorly ventilated space where an air-cooled condenser would recirculate its own heat.

Production that holds in a warm room

The published rating for an air-cooled ice machine assumes a reasonable ambient temperature. Put one in a closed bar cabinet or an interior room in August and real output falls well below the number on the spec sheet. A water-cooled condenser is largely immune to that: heat leaves through the water line, so the 474 pound figure is what the machine actually delivers day after day. That predictability is usually the reason this model is chosen over its air-cooled counterpart.

Low electrical draw

Because the condenser fan is gone and the compressor works against a lower head pressure, the machine only draws 8.45 amps on a 115V single-phase circuit with a 20 amp maximum fuse, and consumes 4.65 kWh per 100 pounds of ice at 90/70 conditions. It is hardwired on site. The offsetting figure is 14.8 gallons of potable water per 100 pounds, so a supply and drain must be available at the location.

Crescent cube ice and bins

Ice forms on double-sided stainless steel KM Edge evaporators into Hoshizaki's crescent shape, which packs a glass without bridging and melts slowly. This is a head only; Hoshizaki lists the B-250, B-300, B-500, B-700, B-800, B-900, B-1150 and B-1300 bins plus the DB-130H, DB-200H and DM-200B dispensers as compatible.
