The iCombi Pro 6-1 from Rational AG - compact combi oven for tight professional kitchens

The iCombi Pro 6-1 opens like a solid steel door to a miniature professional kitchen, hot air brushing your face as trays of vegetables and chicken slide out in a clean, even cloud of steam. In a narrow backroom, a single chef can lean in, tap the touchscreen, and watch the oven quietly handle the next course.

What the iCombi Pro 6-1 does

The iCombi Pro 6-1 from Rational is a compact combi-steamer designed for small restaurants, cafés, and hotel satellite kitchens that still want full-featured professional cooking. It combines convection heat and steam in one chamber, so one unit can roast, bake, grill, and steam on multiple levels without moving pans between appliances.

Rational positions the iCombi Pro family as its flagship intelligent combi oven line, with the 6-1 format typically offering six levels in a narrow footprint, often around 61 cm wide, depending on the configuration. That makes it easier to tuck into tight kitchens where every centimeter of stainless steel against the wall is argued over during planning.

How it feels in daily service

Ask Rational CEO Markus Paschmann what matters most in a combi oven, and he will point to consistency and staff relief rather than headline power numbers. The iCombi Pro 6-1 embodies that philosophy with cooking paths and automatic humidity control designed to take guesswork away from busy line cooks during peak service.

In use, a cook can walk up with flour-dusted hands, tap a pictogram for grilled vegetables or chicken, and let the oven adjust temperature, steam, and fan speed for them. The chamber lighting is bright and tidy, with trays sliding in and out on guides that feel robust rather than flimsy when you are moving heavy gastro pans at speed.

Intelligent cooking and controls

The iCombi Pro 6-1 uses Rational’s intelligent cooking systems, typically marketed under names such as iCookingControl and iLevelControl in earlier generations and integrated into the broader iCombi logic today. These systems monitor the food inside the chamber and adjust temperature, humidity, and airspeed automatically to hit a defined result, such as a certain browning level or core temperature.

Instead of dialing in manual settings, a chef can select a product category and desired outcome, for example “poultry, crispy” or “vegetables, al dente”. The oven then takes care of the rest, including adding steam in bursts or reducing fan speed to avoid drying out items on the top trays while the bottom trays finish cooking.

Why the compact format matters

In many European kitchens, especially in older city buildings, space is the limiting factor rather than demand. The 6-1 format gives roughly six insertion levels for GN pans in a single, relatively narrow column, which makes it possible to run breakfast, lunch, and dinner service from one corner of the kitchen without a separate steam oven and convection oven.

Designers appreciate that the iCombi Pro 6-1 can be stacked in some configurations with another unit or placed on a dedicated stand with integrated tray storage. That helps keep the space underneath controlled, instead of turning it into a random shelf for cleaning chemicals and flour bags.

Cleaning and maintenance in practice

Cleaning is a recurring pain point with heavy-use combi ovens, and Rational has long promoted automatic cleaning programs with solid or liquid cleaner cartridges. On the iCombi Pro 6-1, the user initiates a cleaning cycle via the touchscreen, chooses an intensity level based on how soiled the chamber is, and then lets the machine run through a predefined program overnight.

For staff, that means the worst scrubbing is reduced to wiping down door seals and the glass, while the chamber itself runs a detergent and rinse sequence. The handle, door, and interior surfaces feel smooth rather than raw, which helps prevent food residues from sticking in the first place during service.

Energy use and efficiency

Rational markets the iCombi Pro line as more efficient than older-generation combi ovens, thanks to better insulation, optimized airflow, and more precise control over humidity and temperature. For operators, that can translate into lower electricity or gas bills, depending on the unit configuration, and shorter preheating times before the first batch of bread or roast of the day.

In practice, the compact 6-1 chamber also tends to come up to temperature faster than larger models, which is useful when the first breakfast guests appear earlier than expected. It allows operators to avoid running a large oven idle for long periods just to stay ready for sudden orders.

Where it fits in Rational’s portfolio

Within Rational’s product family, the iCombi Pro 6-1 sits as a core B2B appliance, aimed at professional customers alongside larger formats and the company’s complementary iVario cooking systems. The iCombi Pro range replaces earlier SelfCookingCenter appliances as the primary intelligent combi oven offering.

Sales of the iCombi Pro series help underpin Rational’s position as a specialist supplier of thermal food preparation equipment for professional kitchens worldwide. The company’s portfolio extends from compact units like the 6-1 up to larger 20-level versions for major catering operations and institutional kitchens.

Market availability and price range

The iCombi Pro 6-1 is typically sold through Rational’s dealer network and kitchen planners rather than directly to consumers, with configurations tailored to each project. Pricing varies widely depending on accessories, stainless-steel stands, and cleaning systems, but it sits firmly in the professional segment, not the home-kitchen price range.

In Germany and other European markets, customers usually encounter the oven during planning sessions for new restaurant or hotel kitchens, where Rational consultants and local planners walk them through capacity, energy, and ventilation needs. That means the buying decision is rarely a spontaneous one-click purchase and more a long-term investment.
