RATIONAL presented its first combi oven, the CD 101, in 1976 — three years after the company was founded by Siegfried Meister. The combination of steam and convection enabled chefs to use a variety of cooking methods, such as roasting, baking, and steaming, with just one appliance. Four years later the CD 201 came out, the first floor-standing combi oven to meet the demands of large kitchens with high production volumes.

RATIONAL celebrates 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 donated to the St. Nikolaus Children’s Hospice in Bad Grönenbach.
