Precise cooking cabinet climates are essential in combi ovens because they're fundamental to maximizing productivity and ensuring excellent results. iDensityControl, the iCombi Pro's intelligent climate management system, uses sensors, active dehumidification, and flow-optimized cooking cabinet geometry to maintain exactly the conditions the food needs.​

iCookingSuite makes the iCombi Pro's pre-installed cooking programs a breeze to use. Just specify your desired cooking result, such as browning or degree of doneness, and the intelligent cooking control automatically adjusts any relevant parameters such as temperature, cooking cabinet climate, or cooking time. Sensors detect the size, quantity, and condition of the food and react dynamically as cooking progresses. So you can reliably achieve your desired result without constantly checking or intervening.​

Mixed loads are no problem in the iCombi Pro. The iProductionManager monitors each rack individually. It automatically tracks each product's cooking progress and notifies the user when each is ready. Cooking times are automatically adjusted (e.g., to account for door opening time).​

The iCareSystem recognizes the degree of cleaning required in the iCombi Pro and recommends an appropriate cleaning program – including the necessary quantities of cleaner and descaler. Water and cleaning agent consumption is optimized automatically. Any necessary descaling is automatic as well. Users can also create and save individual cleaning schedules tailored to specific operating times and hygiene requirements.​

With MyDisplay, previously defined dishes can be selected directly on the display with images or icons. Just tap, and the iCombi Pro starts the corresponding cooking process automatically. This makes the system easier to operate and ensures consistent quality.​

ConnectedCooking lets users distribute cooking programs, update cooking system software, and document HACCP data centrally – no matter where the units are located.​
