Technology and features.

In combi ovens, a precise cooking cabinet climate is crucial because it forms the basis for achieving maximum productivity and excellent cooking results. The intelligent climate management function in the iCombi Pro, iDensityControl, maintains the optimal cooking conditions for your food at all times by using sensors, active dehumidification and a flow-optimised cooking cabinet geometry.​

Pre-installed cooking programs are available in the iCombi Pro, which are very easy to use, thanks to the iCookingSuite. Simply specify the desired cooking result, such as browning or cooking level, and the intelligent cooking control will automatically adjust all the relevant parameters, such as temperature, cooking cabinet climate and cooking time. The sensors detect the size, quantity and condition of the food, reacting dynamically to the cooking process. This enables you to reliably achieve your desired result without the need for constant checking or intervention.​

The iCombi Pro makes it simple to handle mixed loads. The iProductionManager monitors every single rack individually. It automatically detects how far along each product is in the cooking process and notifies you when it is ready. Cooking times are automatically adjusted, such as to the time the door remains open.​

The iCareSystem recognises the degree of soiling of the iCombi Pro and recommends the appropriate cleaning procedure, including the necessary amounts of cleaner and descaler. The consumption of water and cleaning agents is automatically optimised. Descaling also takes place automatically if necessary. Additionally, cleaning time schedules can be created and saved individually, and tailored to operating times and hygiene requirements.​

With MyDisplay, predefined dishes can be selected directly on the display using images or icons. Once selected, the iCombi Pro will automatically start the corresponding cooking process. This makes operation easier and ensures consistent quality.​

With ConnectedCooking, cooking programs can be distributed, unit software updated and HACCP data documented centrally, regardless of where the cooking system is located.​
