True Benefits of the RATIONAL iCombi

by Jonathan Andrus


combi oven uses three methods of cooking in one appliance: convection, steam, and a combination of steam and convection. Convection, or the circulation of dry heat, can be used to bake bread or roast meats. The steam function delicately poaches fish, steams rice, or cooks vegetables so they have the perfect texture. When using the combination function, both steam and convection work together to produce results that are moist, flavorful, and have minimal shrinkage.

With the Rational range of ovens, you can relax in the knowledge that the demanding daily kitchen routine is under control: you can bake, roast, steam, blanch, poach and much more, all in a single unit!

AK Success SDN BHD can supply the full range of Rational ovens, including RATIONAL iCombi Pro & iCombi Classic. Rational ovens are available in both gas and electric. Read below to learn the benefits a RATIONAL iCombi Oven.


Combi ovens are a big investment, but when compared to the cost of your overall equipment package, the purchase is worth the initial price. These versatile units make smart investments for the following reasons:

  • Condense Your Cook Line: A RATIONAL iCombi oven can stand in for a steamer and a convection oven easily. And when set to lower temperatures it can do many of the duties of a proofer, holding cabinet, or slow cooker. While the upfront investment is more than any single piece of equipment, it's usually still more cost-efficient than buying multiple pieces of equipment.

  • Cook More with One Oven: RATIONAL iCombi ovens can roast, steam, sous vide, smoke, braise, bake, rethermalize, and oven fry foods. This makes them a great way to boost capacity or save on space by replacing multiple units on your cook line entirely.

  • Precise Temperature and Moisture Control: Accurate controls cook at precise temperature and steam settings, for maximum customization.

  • Programmable Menus: Programmable menus let you hard load or manually input recipes and cook modes. This turns even complex recipes with intricate steam and convection settings into the press of a few buttons.

  • Increased Food Yields: By using both steam and convection in your recipes you can preserve flavors and nutrients, which results in a higher-quality finished product. This is perfect for meats since the moisture from steam helps to prevent meats from drying out and shrinking, keeping cuts tender and juicy.

RATIONAL combination ovens are a great tool to have in your kitchen because they can be easily programmed to whatever settings you may need for a certain dish.

The RATIONAL ovens offer multi-stage cooking cycles which allow you to cook a number of different menu items that would normally require multiple steps and stages otherwise. RATIONAL combi ovens have pre-programmed recipes as well. These ovens allow you to store and create multiple recipes with onboard memory.

The iCombi Pro & Classic both have memory capabilities for more than 200 cooking cycles with various cooking steps. In the end, RATIONAL combination ovens make complex cooking tasks simple; line cooks and less experienced kitchen staff will be able to use this oven with ease.


RATIONAL combination ovens either use touchscreen or dial controls. Either type of control system will work well in your kitchen, it really just depends on your own personal preferences.

  • Touch screen controls allow you to adjust cooking conditions quickly. Just simply enter your settings with a simple touch.
  • Touch models allow for intuitive addition of menu items and quick adjustment with a clear visual of what you want to adjust or add.
  • Dial controls make navigating your cooking menu easy. You can easily scroll to your preferred settings.

Features of RATIONAL iCombi Pro Oven

Guest service knows no breaks but only perfection. Good preparation is all the more critical during rush hours. With a cooking system that takes on routine tasks, masters all conceivable cooking applications, which produces the same quality time and time again, which works intelligently, thanks to iCookingSuite. What is the size, quantity, browning and condition of the food? Recognised, and the cooking parameters are adjusted and on we go. The production planning will now take over. It informs you of what can be cooked together and proposes the time or energy-optimised order. Fresh products, frozen goods, pastries, sides, one or more trays – none of it a problem. Enter the desired result, start the cooking pathway, completed. Perfection in no time at all. There is no need to supervise, no matter who is operating the cooking system.

Efficiency reinterpreted: Forget about the space-consuming cooking appliances and let the iCombi Pro work for you. On less than approx. 1 m2. Meat, fish, poultry, vegetables and baked goods. À-la-carte, catering, delivery service and casual dining. Thanks to the interactive intelligent assistants, iCombi Pro does a lot. With the powerful air circulation and dehumidification, iDensityControl ensures approx. 50 %* more productivity with approx. 10 %* less cooking time. It also delivers consistent and uniform results right up to every corner. At the same time, the intuitive operating concept provides the highest level of user support and minimisation of errors. So that production can simply keep on going.

You have a goal, pursue it without compromise with the cooking intelligence of the iCombi Pro. For example: Sometimes you need to get 5 steaks ready at the same time, sometimes 100, all with the same quality. Either way, produced with the same quality. To achieve this, the iCombi Pro continuously checks the condition of the food against the desired result, calculates the cooking progress and intelligently adjusts the temperature. What if the guests arrive early and the grilled vegetables aren’t ready yet? Then switch from a single to mixed load. The iCombi Pro regulates the cooking parameters so that you can cook both at the same time. Or did you change your mind and want a different result? Then intervene in the cooking process and adjust accordingly. The iCombi Pro will optimally adjust the temperature and time. The result will convince you every time. It can also be reproduced at any time. No matter who is operating the cooking system.

Life in the kitchen: the stress and rush to get everything ready at the same time and on time. A logistical challenge whether using pen and paper or software. No more. Because now the iCombi Pro with the iProductionManager take over: Simply place the dish on the display and it will show you what else you can produce at the same time. You only have to specify whether you want to cook with time, or energy efficiency. The system will monitor each rack individually, so that the cooking times are adjusted intelligently to the quantity and desired result. You decide if you want the food to start cooking at the same time, or finish cooking at the same time. Either way, the iCombi Pro will tell you when something needs to go into the cooking cabinet: the food is ready.

Grilling any quantity of food will leave behind stubborn dirt, meaning the iCombi Pro cannot immediately be used to prepare other dishes. If it weren’t for the iCareSystem. Such as with the ultrafast interim clean in approx. 12 minutes. Then you can quickly move on to cooking the broccoli, without any flavour transfer or unpleasant smells. When it comes to spotless hygiene at the end of the day, the iCombi Pro will tell you whether it is heavily, moderately or slightly soiled. You decide whether to run an eco, or standard clean. With descaling of course. Overnight of course. Always very clean, with 50 %* less chemicals in the phosphate-free cleaner tabs. The iCombi Pro can note your preferences and show you the corresponding cleaning programme the next time.


The RATIONAL iCombi ovens are HACCP Certified ovens, equipped with a 6-point smart probe. Overnight cooking & holding a specific temperature is child's play with the RATIONAL iCombi.


Oh! Before we forget, simply connect the iCombi Pro and the VarioSmoker via USB, start the VarioSmoker and regulate it via the intelligent cooking processes. After just a few minutes of heating up, the intelligence of the iCombi Pro will deliver an optimal and professional cooking and smoking result. You can also use the VarioSmoker in all RATIONAL combi-steamers manufactured from 1997, but in manual mode.

The VarioSmoker works with standard smoking materials such as wood chips or pellets. By selecting smoking materials, the temperature in the cooking cabinet and an appropriate preparation of your raw materials you can determine the aroma and intensity.
