Why Buy the Rational iCombi Classic 20-1/1 Gas Combi Oven?

The multi-talented, manually operated Rational Classic 20-1/1 Gas iCombi Oven (previously the CombiMaster Plus) offers three cooking modes to meet the majority of a professional kitchen's cooking demands. Using hot air convection, steam or a combination of both, you can bake, roast, boil, steam and stew all from one piece of equipment. Packed with intelligent features such as ClimaPlus control to regulate humidity levels and vacuum technology to create the perfect finish, outstanding results can always be achieved. 

Once a cooking process has been perfected it can be stored in the 100 space memory, each able to hold up to 12 steps, ensuring the consistency and repeatability that is vital in a commercial environment. 

Not only is performance exceptional but also the standards of cleaning. Incorporating a cleaning program with menu guided descaling function and an integral hand shower, cleaning internally and externally is taken care of.  

The iCombi Classic gas models are fitted with high performance heat exchangers which have been awarded the Innovation prize from the German gas industry for particularly low emission combustion; the ideal choice for environmentally conscious businesses.

To ensure you are in a position to fully appreciate the advantages that Rational equipment offers, full training is provided along with a support and advice service whenever required.
