  • Recently, the ENERGY STAR program for Commercial Ovens V 3.0 went into effect. This new version, 3.0, requires even more demanding consumption values to be achieved – particularly for electric units. These new standards require higher efficiency cooking, lower idle rates, and even less water consumption. RATIONAL took this opportunity to further improve the energy efficiency and water consumption of our cooking systems. This means that we not only meet, but exceed the new requirements.

    With this, additional unit sizes have now been added to the scope of certified models. We now have ENERGY STAR certification for the iCombi Pro XS and the iCombi Pro 20-full size electric. This is due to the new specifications that allow for electric combi ovens with pan capacity greater than 20 hotel pans and 2/3 size pans to be eligible.

    ENERGY STAR is one of the few globally recognized certifications for high energy efficiency, certified by independent institutes.

    Humidity, air speed, temperature, and steam injection are all coordinated precisely within an appliance that anticipates, learns, remembers, monitors, and adapts....

  • Back in 1973, RATIONAL created its first combi. Since then, we’ve come a long way.

    The iCombi Pro is a huge leap forward. Cooking intelligence with the quality and reliability you have come to expect. The iCombi Pro is ready to take your cooking to the next level.

    Fry, roast, grill, steam, poach, bake, smoke, and reheat – all in one unit. Use steam and convection individually, one after the other, or combined.

    Humidity, air speed, temperature, and steam injection are all coordinated precisely within an appliance that anticipates, learns, remembers, monitors, and adapts.

    The durable touchscreen, logical work steps, and clear, interactive instructions guide users through the production process. Anyone can get it right the first time.

    The iCombi Pro is self-cleaning, featuring an ultra-fast, 15-minute wash cycle, so you can always keep food tasting fresh.

    Beautifully simple. Enormous capabilities. Infinite applications.
