Unox CHEFTOP MIND.Maps™ BIG PLUS 20-Pan Gas Roll-In Combi Oven (XAVL-2021) - NG or LP, 120V or 208/240V, Boilerless

The CHEFTOP MIND.Maps™ BIG PLUS is the oven you build a high-volume kitchen around. Roll in a fully loaded trolley, close the door, and it roasts, steams, bakes or regenerates the whole batch evenly, hour after hour and day after day. This gas model holds 20 GN 2/1 pans or 20 full-size 18" x 26" sheet pans on 2-5/8" spacing and runs from 86°F to 572°F.

It is made for hospitals, universities, hotels, central kitchens and caterers, where one batch has to feed a dining room. Steam is made right in the chamber, so there is no boiler to descale.

What you will notice in day-to-day use

• Load the whole batch in one move. Pans go onto a trolley outside the oven, then the full trolley rolls straight in, so the door is open for seconds instead of minutes (trolley system sold separately).
• Same result, full oven or half empty. ADAPTIVE.Cooking™ reads the load and adjusts time, heat and humidity on its own, so a single tray and a packed oven come out alike.
• Humidity you can actually dial in. Set steam or dry air in 10% steps (CLIMA.Control), and CLIMALUX™ holds it there. DRY.Maxi™ pulls moisture out fast for crisp skins and crusts; STEAM.Maxi™ and PRESSURE.Steam give you dense, saturated steam for vegetables, seafood and bread.
• Ten dishes, one oven, one cook. MULTI.TIME runs up to 10 timers at once, and MISE.EN.PLACE tells you when to load each pan so everything is ready at the same moment.
• Recipes anyone on the line can repeat. Draw a cooking process right on the touchscreen with MIND.Maps™, save it with the 1,000+ program memory, or let CHEFUNOX choose the settings from its built-in library. A new hire gets the same result as your sous chef.
• Cook to temperature, not the clock. The included 4-point MULTI.Point core probe finds the coldest spot in the product, and Delta-T cooking keeps roasts tender and even. A sous-vide probe is available as an option.
• It cleans itself overnight. ROTOR.Klean™ runs the automatic wash, and SENSE.Klean estimates how dirty the chamber is and suggests the right cycle, so you use only the detergent you need.
• Connected out of the box. Built-in Wi-Fi lets you push recipes to every oven, download HACCP records and watch performance from the Data Driven Cooking app.

Choosing your setup

Voltage: the gas burners do the cooking, but the controls and fans need power. Choose 120V or 208/240V single-phase to match the outlet you have; see the table below.

Gas type: runs on natural gas or LP. Choose the one your kitchen uses so it ships set up correctly.

Door hinge: a Left Hinge door swings open to the right; a Right Hinge door swings open to the left. Pick the one that opens away from your prep side or the wall so the door never blocks the cook.

Specifications

Before it arrives

• Water: one cold drinking-water line with a 3/4" NPT connection, 22 to 87 psi (29 psi recommended). Unox requires water that meets its quality spec (free chlorine ≤ 0.5 ppm, chloramine ≤ 0.1 ppm, pH 7–8.5); untreated hard water voids the warranty, so plan on an ion-exchange filter such as Unox PURE where needed.
• Drain: a 40 mm (about 1-1/2") PVC drain on the floor behind the oven.
• Gas: 1" female NPT connection, plus power for the controls and fans (120V/208/240V; see table). A combustion analysis is required at installation.
• Ventilation: follow your local code; a gas oven needs a hood.
• Space: leave room in front of the oven to roll the trolley in and out, and check door widths on the delivery route; the oven is about 6 ft tall.
