Why a combi oven
More output with fewer staff and lower energy costs
With a combi oven you combine multiple cooking techniques in one unit. You work faster, more consistently and with fewer staff. For many professional kitchens this is the central machine.

Frequently asked questions
Questions about combi ovens
What is a combi oven and how does it work?
A combi oven combines hot air and steam in one unit. You can cook multiple dishes simultaneously without flavour transfer, while preserving moisture, texture and nutritional value. Modern combi ovens automatically regulate temperature, air circulation and humidity.
Which combi oven suits my kitchen?
It depends on your daily production volume, available space and desired level of automation. The iCombi Classic suits kitchens with fixed routines. The iCombi Pro is better for kitchens that want maximum automation. We advise based on your specific situation.
What is the difference between a combi oven and a convection oven?
A convection oven only uses hot air. A combi oven adds steam, allowing far more cooking techniques and keeping products moist. For professional kitchens, a combi oven is almost always the better choice.
What is the difference between the Rational iCombi Pro and iCombi Classic?
The iCombi Pro has a self-learning system that recognises products and adjusts processes automatically. The iCombi Classic uses fixed programmes and manual operation. Both are reliable units; the difference lies in the level of automation.
Does JMGT deliver to the German border region?
Yes. As an authorised Rational dealer, we deliver and install in the Netherlands, Belgium and the German border region with direct manufacturer warranty.
How much capacity do I need (GN 1/1, 2/1 etc.)?
As a guideline: 6 levels for 30–60 covers, 10 levels for 60–120 covers, 20 levels for larger production or catering. When in doubt, we always recommend going one size up. A combi oven that is too small is the most common mistake.
