Rational iCombi Classic 20-2/1 Gas Combination Oven

The Rational iCombi Classic 20-2/1 is a large-format gas combination oven designed for high-volume professional kitchens. It operates across three cooking modes — steam, convection and combination — giving the kitchen team precise control over moisture and heat throughout service. The 2/1 GN format accommodates up to 20 full-size pans loaded in landscape orientation, making it one of the highest-capacity models in the iCombi Classic range and a practical choice wherever large batch cooking is a daily requirement.

In a busy kitchen environment, consistency and throughput matter more than headline specifications. The iCombi Classic uses multiple fan wheels to distribute heat evenly across all rack positions, which helps reduce the risk of uneven results when the oven is loaded to capacity. The ClimaPlus humidity management system allows humidity to be adjusted in defined stages, giving cooks meaningful control over the cooking cabinet climate during complex, multi-step processes. Programs can be saved and recalled reliably, which supports consistent results across shifts and reduces dependence on individual cook knowledge during peak service.

From an operational standpoint, the iCombi Classic offers a number of practical advantages for kitchen teams:

• Up to 100 saved programmes with multi-step cooking of up to 12 steps per process
• Intuitive dial-and-push interface with colour display, reducing training time and operator error
• Automatic cleaning with overnight capability and phosphate-free tablets, keeping end-of-service routines manageable
• Integrated scale prevention within the care system, supporting longer-term reliability
• High-intensity LED chamber lighting for quick visual checks without opening the door

The 20-2/1 is a substantial piece of equipment that warrants careful planning before installation. Gas connection, adequate ventilation, and extraction must be confirmed as suitable for a unit of this output before ordering. It will typically require a professional installation, and the physical footprint and weight mean access routes and floor loading should be assessed in advance. The unit can be configured for either natural gas or LPG supply, which is worth confirming with your gas engineer early in the process.

This model is best suited to high-volume operations — large contract catering sites, central production kitchens, stadium and events catering, and large hotel or restaurant kitchens where multiple full-size GN loads are prepared simultaneously throughout the day. For operations with lower throughput requirements, the iCombi Classic is available in smaller rack configurations that may be a more proportionate investment. Equally, for sites requiring more advanced cooking intelligence or connectivity features, Rational produce models with a broader feature set.

A combination oven at this scale is a significant long-term commitment, and getting the specification right before purchase avoids costly complications later.
