Alto-Shaam CMC-H2H DX Converge 2-Shelf Multi-Cook Oven

The Alto-Shaam CMC-H2H DX is a countertop multi-cook oven that houses two fully independent cooking chambers in a single unit. Each chamber operates separately, allowing different cooking modes — steaming, air frying, baking, grilling, and combination cooking — to run simultaneously without any flavour transfer between cavities. The oven uses Alto-Shaam's Structured Air Technology, which delivers precisely directed airflow within each chamber to achieve consistent results across the full cook load.

In a busy commercial kitchen, the ability to run two distinct cooking programmes at the same time without committing two separate pieces of equipment is a genuine operational advantage. The independent chambers mean a kitchen can steam vegetables in one cavity while grilling protein in the other, maintaining throughput during peak service without the coordination challenges that come from managing separate appliances. The self-cleaning function reduces end-of-day labour, and the ventless design removes the need for a traditional extraction canopy directly above the unit, which opens up installation options that would otherwise be ruled out.

Key operational advantages include:

• Two independent chambers eliminate flavour transfer between concurrent cook cycles
• Ventless design allows flexible placement without a dedicated canopy
• Self-cleaning function reduces manual cleaning time between shifts
• Structured Air Technology supports even cooking across both GN tray positions
• Multi-mode capability reduces the need for separate specialist appliances

The CMC-H2H DX runs on a three-phase supply, so the electrical infrastructure needs to be confirmed before installation. At 138kg it is a substantial piece of equipment for a countertop unit, and the surface it sits on — whether a fabricated stand, pass, or prep bench — should be specified to take that load safely. The unit accepts up to two GN 1/1 or two GN 2/3 trays per chamber, which makes it well suited to kitchens producing in controlled batches rather than high-volume continuous throughput.

This oven suits restaurants, hotel kitchens, contract catering operations, and central production units where menu variety demands flexible cooking modes within a compact footprint. It is particularly useful where space is limited and the kitchen needs to consolidate functions without sacrificing output quality. For sites running very high volume across many covers, a larger-capacity unit with additional shelving may be worth considering.

If you are weighing up whether the two-chamber configuration suits your service model, or you want to talk through the electrical and installation requirements before committing, we are happy to work through the details with you.
