Rational Foodservice Equipment Overview
Founded in 1973, Rational manufactures cooking solutions for foodservice operations. This European-based company specializes in creating combi ovens and tilting skillets capable of baking, roasting, deep frying, and poaching. Rational consistently helps operators handle staffing shortages and kitchen logistics by providing multi-purpose equipment. Below, we'll go over Rational restaurant equipment, parts, accessories, and services.
The iCombi Classic & The iCombi Pro

The iCombi Classic is ideal for operators looking for a multi-functional, easy-to-operate unit that increases productivity in commercial kitchens. These units feature ClimaPlus – a system designed to monitor the temperature and air quality of the cabinet while providing steam for cooking. Operators can also program as many as 100 recipes into the control panel on an iCombi Classic, which features three cooking modes: steam, hot air, and combi steam. Every iCombi Classic model also features an automatic cleaning system capable of light, medium, and heavy-duty cleaning.
While the iCombi Classic and iCombi Pro offer virtually the same benefits, the Pro version features intelligent programming that the Classic does not have. The intelligent assistants featured in the iCombi Pro are:
- iDensityControl manages the climate inside the unit. It features a high-performance heating system and steam generators to create the right environment for cooking different types of food.
- The iCookingSuite has 6 operating modes and 5 cooking methods for staff to choose from. The unit then uses sensors to monitor the food and automatically adjusts air quality, temperature, and cooking time.
- Operators can simply use the display to select the dishes they want to prepare, and the iProductionManager shows them what can be cooked together. This system monitors the trays inside the unit separately, adjusting cooking times based on quantity and desired results.
- The iCareSystem self-cleans the iCombi Pro in 12 minutes or less. This feature recommends the amount of chemicals needed to complete the cleaning process and can be set to run overnight to avoid downtime during operating hours.
The iVario Pro
The iVario Pro lets operators boil, roast, and steam large quantities of food four times faster than using multiple units to achieve the same results.1 Like the iCombi Pro, the iVario Pro features three intelligent programming systems.
- Rational's iVarioBoost uses ceramic heating elements that evenly distribute heat when cooking. This system helps save energy by using less electricity than other kitchen equipment.
- The iCookingSuite adjusts temperature, humidity, and cooking time to provide consistent cooking results. Operators can even adjust the cooking path to meet their needs.
- iZoneControl lets operators divide the pan bases into zones then cook food at different temperatures. On larger iVario Pro units, operators can create as many as four zones, and to save energy, the zones not in use are not heated.
Condensate Hoods
The UltraVent® helps operators eliminate the steam that typically comes with combi ovens. When the doors open, the hood extracts the steam from the air which is then condensed. Operators can control the power and quantity of steam extracted with the power control system. These condensate hoods are easy to install and can be retrofitted to electric iCombi Classic and Pro units.
Parts & Accessories
Rational manufactures hundreds of parts and accessories operators can purchase for their iCombi Pro, Classic, or iVario Pro units. Installation kits, air filters, water filtration systems, and door gaskets help these units perform at their best in commercial kitchens, while items such as grill plates, baking pans, and smokers allow operators to further enhance the versatility of their Rational foodservice equipment.
Installation Services
Operators can purchase installation services for the iCombi Classic, Pro, and iVario Pro units. These services may include installing an integrated fat drain, tabletop units, or a water filtration system. Rational’s installation services may offer a pre-install survey, ensuring operations have the right connections and space for the unit. If the pre-install survey is not included in the installation service package, it should be purchased separately to guarantee smooth operation. The installation services do not include travel costs and are limited to the continental United States.
