Commercial microwave ovens — heavy-duty units built for the reheat and steam cycles of a busy kitchen, not a domestic counter.

By wattage and duty class — higher wattage and heavy-duty builds suit busier kitchens. We'll match to your use.
Many have preset pads for repeatable reheating across staff. We'll note features per model.
