Rational iCombi Pro by Rational AG - smart combi oven pushes kitchen efficiency

The Rational iCombi Pro sits humming softly in a stainless-steel hotel kitchen, steam curling from the door seal as trays of vegetables, chicken and baguettes share the same space. One touch on the touchscreen and chef Martin Braun lets the oven think for him.

Intelligent paths in one cabinet

Rational iCombi Pro is a combi-steamer line that uses the company’s iCookingSuite to manage time, temperature, humidity and airflow for each dish in the cabinet. A chef selects the food type and desired browning, and the oven guides or automates the process. The system continuously measures and adjusts the climate and air speed to hit the target result.

An important feature for busy operations is iProductionManager, which allows different dishes on multiple trays to be cooked simultaneously with automatically staggered start and end times. The cabinet view shows each tray as a tile, with the software calculating when to load and remove food to avoid bottlenecks. In practice, this means a single iCombi Pro can finish side dishes, protein and dessert inside one service window without constant supervision.

From 6 to 20 trays, tailored to the kitchen

Rational offers the iCombi Pro in several sizes, ranging from compact 6-1/1 units up to large 20-2/1 models designed for central production kitchens. Each size is available as electric or gas, with options for fresh steam generation and built-in condensation hoods depending on the installation. This modularity lets a hotel breakfast station, a chain restaurant and a hospital kitchen choose different footprints while staying on the same platform.

The flagship 20-1/1 and 20-2/1 models are built for roll-in racks and high throughput, while the 6-1/1 and 10-1/1 variants sit on stands or bases under standard hoods. Rational’s product manager for combi systems, Thomas Lang, often points to the smaller units as the entry point for mid-size operations, where a single oven replaces several conventional appliances. For investors, this spectrum means the same technology can scale from a single-site install to multi-outlet roll-outs.

Cleaning and energy monitoring baked in

Besides cooking, the iCombi Pro integrates iCareSystem, an automatic cleaning program that uses liquid cleaner and rinse tabs to wash the cabinet and descale the steam generator. The operator chooses the cleaning level based on soiling, and the oven suggests the program and chemical quantity. This reduces manual scrubbing and helps maintain hygiene standards, which is critical for foodservice chains.

An energy consumption display and data export function give operators transparency on electricity or gas usage over time. Kitchens can pull reports and compare locations, feeding into broader efforts to cut utility costs and document sustainability initiatives. For Rational, these digital tools create a bridge between the hardware sale and ongoing customer relationships via software updates and advisory services.

Chef guidance in everyday service

In the iCombi Pro, the touchscreen interface offers guided cooking for common dishes like roast chicken, baked goods and grilled vegetables. The iCookingSuite suggests loading densities and tray positions, making it easier for less-experienced staff to hit consistent results. Chef Martin Braun describes how a junior cook can follow on-screen prompts, while he focuses on menu composition and plating.

Saved cooking programs and favorites allow chain restaurants to standardize recipes across outlets. When a new store opens, it can receive the same iCombi Pro programs as the existing network, reducing onboarding time. Rational has highlighted in its marketing materials that quick service and casual dining concepts use this consistency to support brand promises, even when staff turnover is high.

Global footprint and retrofit demand

Rational AG, headquartered in Landsberg am Lech in Germany, positions the iCombi Pro as part of its core combi-steamer portfolio for professional kitchens worldwide. The company reports tens of thousands of units installed across Europe, North America and Asia, with ongoing retrofit demand as older combi models reach replacement age. This installed base makes follow-up sales and service contracts relevant for revenue stability.

New builds in hotels, canteens and dark kitchens also add volume. Rational’s regional teams work with planners and kitchen designers to specify iCombi Pro units in layouts. That design-in approach ties the oven line to growth in commercial real estate and foodservice concepts. For Rational AG stock, that breadth of application means the combi segment remains a central, recurring revenue driver alongside newer product families.
