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


This unit is commonly installed in large catering hubs and hotel production kitchens in Riyadh and Jeddah. It supports high meal counts per shift, making it suitable for workforce dining facilities and banquet operations where large tray capacity is required.

The internal control system regulates humidity and airflow to maintain stable chamber conditions across twenty GN levels. This enables mixed-product loading while reducing uneven cooking between rack positions during bulk roasting or baking cycles.

With twenty 1/1 GN trays, the oven supports substantial batch preparation in a single cycle. Throughput depends on portion size and recipe type, but it is designed for high-volume institutional kitchens handling continuous service in industrial zones such as Dammam.

Gas variants require compliance with Saudi commercial kitchen ventilation standards and approved gas line installations. Proper inspection of connections, drainage, and steam components ensures operational safety under extended daily usage.

The integrated cooking assistants monitor load size and adjust parameters automatically. This reduces manual intervention and allows staff to focus on preparation and plating tasks during high-demand service periods.

Regular cleaning cycles, descaling routines, and inspection of door seals and water filtration systems are essential. Scheduled technical servicing helps maintain consistent steam generation and airflow performance in Saudi industrial kitchens.
