Your customers will taste the quality. Every day.

Unmatched food quality is only possible with high-performance equipment—especially when it comes to preparing large quantities. That’s exactly where our patented HiDensityControl® comes in.

It circulates heat, air and moisture throughout the cooking cabinet uniformly and intensively—in whatever way is best 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.

Highly sensitive sensors detect and identify the current conditions inside the cooking cabinet every second, so that energy levels can be optimised in accordance with the needs of the food. And it all happens precisely and efficiently.

The results: Consistently high food quality and minimal resource consumption, from the first rack to the last.

Cooking cabinet management.
Heat, air, and moisture.

Intelligent climate management.
The humidity sensor also accounts for the food’s natural moisture levels, and allows cooking cabinet climate parameters to be set and adjusted to one percent precision. The results? Browned, juicy roasts and light crumb.

Dynamic air circulation:
The high-performance fan impeller adjusts its speed and direction of rotation depending on product types, quantities and cooking states. This ensures optimum air distribution for uniform results.

Active dehumidification:
Innovative vacuum technology dehumidifies the cooking cabinet quickly and efficiently, providing crisp crusts, crunchy breading and attractive grill marks with delicious roasted flavours.

Fresh steam generator.
Hygienic steam at the push of a button, any time.

Precise steam temperatures and maximum steam saturation—even with full loads, and even at temperatures as low as 30 °C—guarantee top-quality, healthy, nutritious results with no need for an elaborate and expensive water softening system.
