Rational iCombi Pro 20-1/1 Electric Combination Oven

The Rational iCombi Pro 20-1/1 is a full-size, twenty-grid electric combination oven designed for high-volume professional kitchens. It operates across steam, convection, and combination cooking modes, with the cooking intelligence built into the unit itself — automatically adjusting humidity, temperature, and airflow based on the load it detects. This is not a passive piece of equipment; it monitors and responds throughout the cooking process.

In a busy service environment, the iCombi Pro is well suited to high-throughput production. The unit's load recognition allows it to handle mixed loads — different foods cooking simultaneously — while maintaining the correct conditions for each. For kitchens running breakfast, carvery, or multi-course banquet service, this kind of consistency across a large cabinet is operationally significant. Recovery between loads is handled efficiently by the system, which reduces the downtime between batches that can affect service flow under pressure.

From a practical standpoint, the iCombi Pro addresses several operational pressure points:

• Programmable cooking processes reduce reliance on individual chef knowledge and help maintain consistency across shifts
• The iProduction Manager function assists with sequencing and planning output across multiple dishes
• Automated cleaning cycles reduce cleaning time and chemical usage compared with manual processes
• Wi-Fi connectivity allows remote monitoring and access to Rational's ConnectedCooking platform for recipe management and diagnostics
• The cooking cabinet design supports efficient energy transfer, which matters when the unit is running for extended service periods

As a twenty-grid full-size unit, this oven requires careful consideration before installation. It is a substantial piece of equipment in terms of footprint, weight, and service requirements. A Type 2 canopy ventilation system will be required in almost all UK installations, and the electrical supply must be confirmed before ordering — three-phase supply is standard for a unit of this capacity. Water inlet and drain connections are also required, and water treatment is strongly recommended to protect the steam generation system and maintain warranty conditions. Access routes and floor loading should be checked at the planning stage.

The iCombi Pro 20-1/1 is best suited to large-scale catering operations: contract caterers, hotels, hospitals, stadium and event catering, and high-volume restaurant kitchens where consistent output across a large number of covers is a daily requirement. Kitchens with lower throughput or more limited infrastructure may find a smaller-capacity model a more practical fit, and for sites where output requirements are significantly higher still, rack oven configurations are worth considering.

This is a significant capital investment and a technically involved installation. If you'd like to talk through whether the 20-grid specification suits your operation, or discuss what the installation involves in practice, we're happy to work through it with you before you commit.
