A double anniversary for the world market leader: 50 years of RATIONAL combi ovens, with 1.5 million units built.

In 2026, RATIONAL will celebrate two milestones: 50 years ago, the global market and technology leader in thermal food preparation launched its first combi oven. Combining heat and steam in one unit has fundamentally changed the way professional kitchens work. The 1.5 millionth combi oven rolled off the production line just in time for this occasion. The anniversary unit, which features a golden dial, was handed over to the St. Nikolaus Children’s Hospice in Bad Grönenbach at the beginning of February.
