Optimus — product fundamentals

Frequently asked questions

Does the Optimus plug into a standard outlet?

Optimus runs on a 120V / 20A circuit using a NEMA 5-20P plug. Most hospital and senior living kitchens already have these. Actual draw is 14A / 1400W.

Can the Optimus run on a 15-amp circuit?

No. Optimus requires a 20A circuit. The plug is NEMA 5-20P (the T-slot 20A configuration). Do not run it on a 15-amp circuit. Power planning details.

How many meals does the Optimus hold?

The Optimus ONE-20 holds 20 meals — 10 per side, at 4-inch tray spacing. ONE-22 and ONE-24 capacity configurations are available; contact us for current per-model specifications.

How much does an Optimus cart weigh?

The ONE-20 is under 430 lbs. Weight figures for ONE-22 and ONE-24 come on individual spec sheets — contact us for the current numbers per model.

Where are Optimus carts made?

Optimus carts are designed and built in West Lafayette, Ohio, by JonesZylon. Made in USA.

Is the Optimus made of stainless steel?

Yes. The exterior is 18-gauge stainless steel. The frame is 16-gauge stainless with reinforced cross channels. Door handles are antimicrobial.

What size casters does the Optimus have?

Six 6-inch premium casters that allow turn-on-axis maneuvering. (MealPro carts ship with 8-inch casters — they are different sizes; do not interchange specs across the two product lines.)

How wide is the Optimus, and will it fit through standard hospital corridors?

The Optimus measures 51.25 inches wide × 32 inches deep × 56.5 inches tall. It clears most modern hospital corridor and elevator dimensions. Confirm against your facility's drawings if there are known tight points.

How does Optimus keep hot food hot and cold food cold on the same tray?

A center wall separates the cabinet into two active zones. Side-mounted refrigeration runs on one side; convection heat on the other. Both run continuously while the cart is plugged in or in motion, so a hot entree and a cold salad arrive at the right temperatures on one tray.

Is the Optimus a rethermalization cart?

No. Rethermalization carts re-heat pre-cooked, refrigerated food to serving temperature, usually inside a docking station. Optimus is an active hot/cold delivery cart — it holds already-prepared hot food hot and cold food cold during transport. What is rethermalization?

Does the Optimus need a docking station?

No. Optimus is a self-contained cart. There is no wall unit, no base station, no nesting infrastructure. Plug Optimus into a standard 120V/20A outlet and roll. Docking vs self-contained.

What happens if the cart is unplugged during transport?

The cabinet is insulated. Brief unplugged transport between charging stations and patient rooms is the normal operating mode. Hot and cold zones each retain their target ranges during typical hospital tray-delivery distances.

How is Optimus different from a passive insulated cart?

Passive insulated carts have no active heating or refrigeration — they slow temperature change but don't prevent it. The Optimus runs active heating and active refrigeration continuously, holding both temperatures across multi-hour service windows. Hot/cold cart architectures explained.

Can the Optimus replace my facility's pellet system?

In most hospital tray-service and LTC unitized-tray workflows, yes. The pellet/dome system gets replaced by the active hot/cold cabinet — no pellets, no chargers, no domes. Cold food is now actively refrigerated rather than relying on cabinet insulation. Read the full pellet replacement guide.

Do I have to replace my entire pellet system at once?

No. Most facilities run a phased migration: pilot one floor or one shift, validate, then expand. Pellet replacement playbook walks through the staged rollout.

What about heated domes — do I keep them?

No. The Optimus replaces the pellet+dome combination entirely. The cabinet's active heating handles what the dome's passive insulation used to do, and the active refrigeration handles cold zones the dome system never managed.

How does the Optimus compare to Aladdin Convect-Rite III?

Convect-Rite III is a cook-chill rethermalization system requiring 208V/30A docking stations at floor pantries. Optimus is a self-contained 120V active hot/cold cart that doesn't need docking infrastructure. The two systems serve different production models: Convect-Rite for cook-chill central kitchens, Optimus for cook-serve unitized tray service. Full comparison.

How does the Optimus compare to Dinex Meals On Command II?

Both are 120V/20A active hot/cold delivery carts. Wedges include construction (Optimus stainless vs MOC II thermoformed plastic panels per matrix v2), data logging (Optimus 30-day USB logger vs MOC II LCD-only), form factor (Optimus under 430 lbs vs MOC II 485 lbs per matrix v2), and Made-in-America (Optimus per JZ sell sheet; matrix v2 records MOC II as not-Made-in-America). Full comparison.

How does the Optimus compare to Cambro Camtherm?

Camtherm is primarily a passive insulated holding cabinet, available in active single-mode hot or cold variants. Optimus is active dual-temperature simultaneous on one tray. Different architectures for different workflows. Full comparison.

Optimus vs MealPro — which one do I want?

MealPro is the higher-capacity dual-cabinet line; Optimus is the compact single-cabinet line. MealPro fits high-volume centralized kitchens; Optimus fits hospital tray service, room service, and bedside delivery. Full Optimus vs MealPro comparison.

Is the Optimus HACCP certified?

No equipment is HACCP certified — HACCP is a process, not an equipment certification. The Optimus supports HACCP documentation by capturing continuous hot- and cold-zone temperature data through its 30-day USB logger. HACCP documentation guide.

What does the 30-day USB temperature logger actually capture?

Hot-zone and cold-zone temperatures, recorded continuously, stored on the cart's onboard USB memory for up to 30 days per cycle. Pull the file via standard USB; opens in Excel or any text editor. Becomes the records portion of your HACCP documentation.

What standards is the Optimus listed under?

NSF and Intertek listed at the high level. Specific listing numbers are available on request. NSF/ANSI Standard 4 is the relevant equipment standard for powered hot food holding and transportation equipment.

What's the difference between 120V and 208V meal delivery carts?

120V carts plug into standard outlets; 208V systems require dedicated three-phase circuits typical of docking stations. Most US hospital and LTC facilities have 120V/20A receptacles widely available; 208V/30A is selectively installed for retherm or other heavy equipment. Full power planning guide.

Does Optimus need a dedicated circuit?

Optimus runs on a standard 120V/20A circuit. It does not require a dedicated circuit, but it should not share a circuit with other heavy continuous loads. Standard pantry receptacle on a 20A circuit is the typical install.

What's a NEMA 5-20P plug?

A standard 120V / 20A plug, recognizable by the T-slot configuration on its corresponding receptacle. Optimus uses NEMA 5-20P. The 15-amp version (NEMA 5-15P) does not properly mate with the 20A receptacle; never adapt one to the other.

How do I get pricing on Optimus?

Is the Optimus suitable for long-term care and SNF?

Yes. The 14-Hour Rule, person-centered dining models, and bedside service in resident rooms all fit Optimus's compact form factor and active dual-temperature operation. Optimus for LTC and SNF.

Can the Optimus be used in behavioral health facilities?

Yes, in conjunction with appropriate dining safety dinnerware. JonesZylon's MaxFlex line addresses the dining-safety side. Behavioral health dining.

Is the Optimus appropriate for correctional foodservice?
