30 % less space requirement*

Together, the iCombi Pro and iVario Pro replace approx. 90% of conventional cooking equipment. So out with the tilting pan, boiling pan and deep-fat fryer – and in with freedom of movement. Or additional shop space.

Up to 25 % less consumption of raw materials*

The iCombi Pro sensitively adjusts its cooking processes which reduces weight and cutting loss. Nothing burns in the iVario Pro, and nothing boils over. This results in almost no loss at all. Together, this makes up to 25 % less consumption of raw materials.

* Compared to conventional cooking technology

It pays off: The bottom line is the extremely quick amortisation, but it's also fun to work with.
