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 intelligence built directly into the unit — automatically adjusting humidity, temperature, and airflow in response to the load it detects. This is not a passive oven that simply holds a set point; it monitors and responds throughout the cooking process.

In sustained service environments, the iCombi Pro is well suited to high-throughput production. Its load recognition allows it to manage mixed loads — different foods cooking simultaneously — while maintaining appropriate conditions for each. For kitchens running breakfast service, carvery, banqueting, or multi-course production, consistency across twenty grids is operationally significant. The system manages recovery between loads efficiently, which helps reduce batch downtime during peak service.

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

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

As a twenty-grid unit, this oven requires careful pre-installation planning. A Type 2 canopy ventilation system will be required in almost all UK installations. Three-phase electrical supply is standard for a unit of this capacity and must be confirmed before ordering. Water inlet and drain connections are also required, and water treatment is strongly recommended to protect the steam generation system and maintain warranty conditions. Footprint, access routes, and floor loading should all be assessed at the planning stage — this is not a unit that can be placed without prior preparation.

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. For sites where production demands are greater still, rack oven configurations are worth considering.

This is a substantial capital investment with a technically involved installation behind it.
