Spotlight on Rational : The Evolution of Intelligent Cooking.

Few names in the catering world carry as much weight as Rational. Synonymous with reliability, innovation, and precision, Rational has transformed commercial kitchens worldwide with its iconic combi ovens.

This spotlight on Rational explores the company’s roots, how its cooking systems revolutionised foodservice, and why chefs across the globe continue to rely on their intelligent technology every day.

A Brief History of Rational

Rational was founded in Germany in 1973, initially focusing on thermal food preparation. The company’s breakthrough came in 1976 with the launch of the world’s first combi-steamer, combining dry heat and steam in a single appliance. This marked the beginning of Rational’s mission to provide intelligent cooking systems that simplify and improve professional kitchen workflows.

Over the decades, Rational has grown into a global leader, serving customers in over 100 countries. Their reputation is built on robust engineering, smart cooking technology, and a relentless focus on user experience.

What Is a Rational Oven Capable Of?

Rational ovens are far more than just ovens—they’re intelligent cooking systems capable of replicating a wide range of cooking processes with precision and consistency. Here’s what they can do:

Steam, Roast, Grill, Bake, and Regenerate in one unit

iCookingControl® technology automatically adjusts cooking parameters in real time

iDensityControl® ensures uniform cooking, even with full loads

SelfCookingCenter® and iCombi Pro® models learn and adapt to your cooking habits

Programmable cooking steps allow full menu automation

iCareSystem® provides automatic cleaning cycles based on usage

Whether you’re steaming delicate vegetables, baking pastries, roasting meat joints, or regenerating plated meals, Rational ovens handle the job without compromising quality.
