Rational equipment is the workhorse of professional kitchens — and when one stops working, it stops the entire pass. Our engineers are trained on the full Rational range, from older SelfCookingCenter units through to the latest iCombi Pro and iCombi Classic generations, including the ConnectedCooking platform.

We hold trade accounts with Rational UK for genuine OEM parts — steam generators, doors, sensors, control PCBs, gaskets and the full ClimaPlus consumables range — so the part you need is rarely more than a day away.
