Ice machine for a food truck (power, drain, water)

Updated 2026-08-30. Independent guide — not a dealer quote.

On a truck the machine is a utilities problem. Brand comes last. If the circuit, drain, and water tank are wrong, a 200 lb modular head is scrap metal on wheels.

This is not a mobile-food-code manual. Confirm electrical, plumbing, and sanitation with the authority that inspects the truck.

Power

Most compact commercial undercounters in this directory are 115 V / 60 Hz / 1 phase, 15 A max fuse, cord and NEMA 5-15P.

Model Amps on the cited page Plug Why it matters on a truck
Hoshizaki AM-50BAK 2.0 A 5-15P, 6 ft Lowest draw of the compact top-hat class we listed
Hoshizaki C-80BAK 2.8 A 5-15P Cubelet; 15″ cabinet
Hoshizaki KM-81BAK 2.4 A 5-15P Crescent; 17.75″ × 39″
Manitowoc UYF-0140A 5 A (U-140, 115 V) 5-15P Larger cabinet and bin
Ice-O-Matic ICEU150HA 9.7 A on one dealer sheet; confirm OEM Corded 115 V Higher make, higher draw — measure the generator
Modular 115 V heads (C0330, IYT0450, KM-520) 10–15 A class Often hardwire, no plug Usually a bad fit for a truck

A generator that is already running HVAC, a fridge, and a flat top may not have another 8–12 A of compressor inrush. We do not publish locked-rotor amps here; they are on the wiring diagram. If the truck is 208 Y / 120 or inverter-heavy, have an electrician read the data plate.

Do not use a household countertop “nugget” machine as if it were NSF commercial equipment unless the listing says it is.

Drain

Ice machines dump melt and harvest water. Options:

  • Gravity drain to the wastewater tank. Needs consistent fall. Hose size is on the spec (often 1/2″ or 3/4″ ID).
  • Listed drain pump (example: Hoshizaki accessory HS-5061 on AM/C/KM compact units; Scotsman CU50PA has a factory pump and 10 ft tube on the CU50 sheet).

Gray-water capacity must include ice melt, not just the hand sink. A clogged pump kills the machine and can flood the cabinet.

Water

  • Potable supply only. A food-grade tank and pump with enough flow and pressure for the spec (Hoshizaki compact sheets list roughly 10–113 psig; Manitowoc NEO lists 20–80 psi). Too little pressure and the harvest cycle fails.
  • A filter that is actually rated for ice machines. Truck water is often worse than a city riser. See filters.
  • Winterize: drain the machine to the manufacturer’s winterization steps. Frozen evaporator = replace, not repair.

Water-cooled condensers need a second water path and dump heat into the wastewater tank. They are almost never the truck answer. Use air-cooled, and give the louver the clearance on the sheet. Front-in / front-out cabinets (AM-50BAK, C-80BAK, many KM undercounters) exist for tight holes.

Heat and vibration

A closed commissary kitchen at 90°F already derates production. A steel box in August is worse. Use the 90/70 column. Soft-mount if the manufacturer allows it; do not assume a restaurant machine likes highway vibration — that is a warranty conversation with the dealer, not something we invent here.

Models that fit the usual truck envelope

If you need Look at Cited make / bin Cabinet
Lowest draw, hotel-style cube AM-50BAK 54 lb / 27 lb 14.875″ × 22.625″ × 33.5″
Chewable ice, 15″ C-80BAK 92 lb / 27 lb Same family; UL outdoor on page
Crescent for cups KM-81BAK 98 / 76 lb; 38 lb bin 17.75″ × 24″ × 39″
More bin UYF-0140A 137 / 100 lb; 90 lb bin 26″ × ~28.5″ × 38.5″
Gourmet for a cocktail truck CU50 65 / 49 lb; 26 lb 14.9″ × 22″ × 34.4″

If you bag ice at a commissary and only hold it on the truck, you may not need a maker at all — a bin and a scoop protocol might be enough. That is an operations choice, not a model recommendation.
