Your customers will taste the quality. Every day.


Superior food quality can only be achieved if there is always sufficient power, especially when it involves the preparation of large quantities. This is what the patented HiDensityControl does.

It distributes the heat, air, and humidity in the cooking cabinet uniformly and intensively, specifically for the quality and quantity of your products.

Benefits for you at a glance:
  • Exceptional uniformity from the first rack to the last
  • Crisp crusts and crunchy breadings
  • No drying out, even of delicate foods
  • Traditional grill marks even with large quantities
  • Short preheating periods, and thus minimum energy consumption

Precision means top quality.
Automatic cooking cabinet climate adjustment.

Every second, highly sensitive thermocouples detect and recognize the current cooking cabinet conditions, so that the required quantity of energy can be optimally adjusted to the food. This takes place precisely and efficiently.

The result: consistent high food quality with minimal use of resources, on every single rack.
