Product Description

The Hoshizaki KM-322MAK is a 22-inch air-cooled modular Crescent Cuber head making 489 pounds of ice per 24 hours. It is part of Hoshizaki's newer MAK generation, which moves the refrigeration circuit to R290 — a natural hydrocarbon refrigerant with a global warming potential in the single digits rather than the thousands.

R290 natural refrigerant

R290 is propane, used in a very small sealed charge — 5.1 ounces on this machine. The practical arguments for it are regulatory and thermodynamic: it is not on any HFC phase-down schedule, so a machine bought today does not become a refrigerant liability in ten years, and it transfers heat well enough that the unit hits 489 pounds a day while drawing 9.7 amps on a 115V circuit. It is ENERGY STAR qualified at 4.9 kWh per 100 pounds at 90/70 conditions.

Slim 22-inch footprint

Twenty-two inches wide and 28 inches tall, the head fits a narrow bin line-up where a 30-inch machine will not. That makes it the usual answer in bar backs, coffee shops and satellite kitchens where the ice machine has to share a wall with everything else. It pairs with Hoshizaki's B-300SF and B-500SF bins and the DB-130H dispenser.

Maintenance built for a busy kitchen

Hoshizaki's CleanAssist routine brings the cleaning cycle down to about an hour, which is the difference between a task that gets done on schedule and one that gets postponed. Ice forms on stainless steel evaporators into the crescent shape — dense in the glass, slow to melt, resistant to bridging in the bin.
