3.1 Introduction
All Cold Display Cabinets are synonymous in
construction and therefore you will have the
possibility of an optimum integration in a com-
plete display conception. An adjustable tem-
perature control enables you to set the desired
cooling temperature. We guarantee a constant
temperature even in case of opened doors.
The temperature rises only after some
minutes. The Cold Display Cabinets show a
high cooling performance. Within the Cold
Display Cabinets, the cooling convection pro-
vides a stable temperature. The set tempera-
tures are reached within one hour, the degree
of condensation is low.
The maximum holding time depends on the kind of product and on the products
starting temperature. It might be limited by national or local regulations. Never
equip the cabinet with warm or hot products.
3.2 Special features
• Ergonomic, stylish design
• Maximum product visibility by curved front glass
• Optically doubled foodpresentation by mirrored sliding doors
• All models are available as self-service equipment for impulse buying
