Rational iCombi Pro 20 x 1/1 GN
The Rational iCombi Pro 20 x 1/1 GN is a high-capacity combi oven developed for commercial and institutional kitchens in Oman. It integrates steam injection and forced hot-air circulation to support large-batch cooking processes. With twenty 1/1 GN tray capacity and a working temperature range from 86°F to 572°F, it is suitable for food production environments requiring stable thermal control and efficient handling of high meal volumes.
The chamber supports twenty GN trays mounted on a wheeled rack with 63 mm spacing, allowing efficient movement between preparation and cooking zones. Steam mode operates up to 266°F, while convection and mixed modes extend to 572°F, covering roasting, baking, and steaming requirements.
In Omani procurement contexts, durability and maintenance efficiency are primary considerations. The oven’s climate management system regulates moisture and airflow distribution across all rack levels. The automated cleaning and descaling program reduces manual intervention and supports long-term reliability, especially in facilities managing continuous institutional meal preparation.

The following intelligent assistants are available
iDensityControl
iDensityControl is the iCombi Pro’s intelligent climate management. The interaction among intelligent sensors, a high-performance heating system and fresh steam generator, and active dehumidification ensures that the right cooking cabinet climate is always available. Intelligent air circulation ensures the best possible energy input into the food. Consequently, this ensures extraordinary productivity while maintaining high levels of food quality, even cooking and minimum energy consumption.
iCookingSuite
The iCookingSuite is the iCombi Pro’s cooking intelligence. The user starts by selecting the right cooking path for the food, choosing from among 6 operating modes and / or 5 cooking methods. Users also specify the desired cooking result. The unit suggests settings for browning and degree of doneness. Intelligent sensors detect the size, quantity and condition of the food. While the cooking path is in progress, the system adjusts key parameters like cooking cabinet temperature, airspeed, and cooking time accurately to the second. The selected desired results are achieved, yielding the best possible quality in the shortest possible time. It is possible to optionally influence the cooking sequence and adapt the cooking result. Users can change to iProductionManager or manual mode at any time. Thanks to iCookingSuite you can simply save time, raw materials, and energy while maintaining a standardized food quality without having to check the procedure.
iProductionManager
iProductionManager intelligently and flexibly organizes the production process. This includes which products can be prepared together on different trays, the ideal sequence of dishes, and monitoring the cooking sequence. iProductionManager supports users with prompts to load or unload dishes. Depending on kitchen processes you can freely position orders (up to two per level) or schedule them on the basis of a certain target time. iProductionManager arranges the sequence of dishes accordingly and automatically specifies the correct settings. Users decide whether dishes are cooked based on optimum energy consumption or a certain target time. Simple monitoring activities are no longer required, saving you working time and energy.
iCareSystem
The iCareSystem is the intelligent iCombi Pro cleaning and descaling system. It recommends the amount of chemicals and ideal cleaning stage from the nine available programs based on usage and any limescale in the steam generator. Ultra-fast interim cleaning cleans iCombi Pro in only 12 minutes, all cleaning programs can also run overnight without the need for supervision. The iCareSystem is particularly efficient and environmentally friendly, consuming small quantities of phosphate-free care products, water, and energy. This means that the iCombi Pro is always hygienically clean without manual work and at minimal costs.

Frequently Asked Questions
In Oman, this model is typically deployed in large hotel banquet kitchens in Muscat and institutional catering facilities in Sohar. It supports high-capacity cooking where multiple GN trays must be processed under controlled steam and hot-air conditions.
The cabinet uses regulated airflow and humidity control to distribute heat evenly. Sensors continuously monitor internal conditions and adjust parameters during the cooking cycle, minimizing variation between upper and lower rack positions.
Yes. The design supports repeated batch processing throughout extended shifts. It is frequently used in defense catering, industrial canteens, and centralized kitchens where meal preparation is scheduled and standardized.
Higher mineral content in coastal water supplies can lead to scale buildup in steam generators. Using proper filtration and performing routine descaling cycles helps maintain stable performance and reduce maintenance downtime.
The wheeled rack allows operators to load trays externally and move them safely into the cabinet. This reduces manual lifting inside the chamber and improves workflow organization in large Omani kitchens.
Managers should monitor door gasket condition, drainage efficiency, water pressure stability, and cleaning program performance. Periodic technical checks ensure reliable steam output and long-term operational consistency.
